Incredible watch! Does it All! I can't say enough about it!
This is my third Amazfit watch. I started with the Bip 3, moved up to the original GTR (Great looking watch with great features - was my favorite!). I hesitated to go for the GTR 2 or 3 simply because the GTR was such a great watch - super good battery life, accurate readings, etc. But when the GTR 4 came out, I decided it was time for an upgrade. I've been so pleased with this watch. It's such a step up from my other watches. I love how I can customize my swipe left or right (with a continuous loop, no less) to have my favorite functions - Top widgets, steps, heart rate, Blood O2, music, compass (with altimeter and barometer as well), weather, and the shortcut cards that allow me to add even more functionality at my wrist (Calendar, upcoming alarm, countdown, stopwatch, one-tap measuring, sleep, PAI). I don't use Alexa, but I have used the offline voice control, which works pretty well; but with all the apps right there, I prefer to swipe. I love the membership card feature (bar codes from cards for grocery stores, pharmacy, Red Cross, etc.) and I always feel very "techy" when I scan myself in at the platelet center or the self-checkout. The weather app is accurate with a five-day forecast, and I love the sun and moon feature (helpful for hiking to know the sunrise and sunset times, and to know if I'll have any moonlight at night). The phone app is awesome. It's always nice to take phone calls from my bride when I'm at work or hiking without having to take out my phone. The sound on my end is great and she says the microphone sounds better than my phone! I can use the number pad or my contact list to make calls as well. I also love being able to respond to texts (I get the full message, by the way, not just a line or two) with one of 10 pre-set responses, or even emojis. It's more than a novelty and I really enjoy being able to use it. The workouts are more than I will ever use. Mostly I use walking, climbing (hiking), biking, strength training, indoor biking, and a few others. I wish they had some workouts for when I'm out in the yard raking leaves or chopping wood, but I find other exercises that serve as equivalents. I love all the information the app gives me about workout duration, calories burned recovery time, etc., as well as the little "Hoorays!" for achieving goals, and the suggestions, reminders, and coaching it gives as well. As far as the heart rate, blood 02, and steps, I find those to be very accurate (My vitals are checked twice a month when I give platelets.), so it gives me an good overall picture of my health. The sleep tracking is better than before. My other watches would only measure sleep at night, but since I work nights and sleep during the day, it wasn't as helpful. The GTR 4 measures "naps" so I'm getting a more accurate picture of my sleep. And on the weekends when I switch to sleeping at night, the readings give me a very good general sense of my sleep patterns, and I'm happy with that. What more can I say? There's a calculator, flashlight (decent for what it is), stopwatch, alarms, find my phone, camera remote, stress readings, etc. I love the one-tap measuring. I just hit that button and in 45 seconds get a good overall picture of my health. The music player app works well (a remote control for your phone). I haven't used the music download feature, because I would rather save the memory (lots of memory, by the way) for map data, and I always have my phone with me, so having music on the watch would be redundant for me; but it's a great feature nonetheless. I've also downloaded a bunch of apps from their proprietary app store - games, tip calculators, unit converters, and even navigation apps. No, I don't have detailed topo maps for the watch for hiking, but it does give me some basic functionality in that regard. My hiking, biking, and walking workouts are sent to the app and displayed on my phone. There are a ton of great watch faces, many of which can be customized, all ranging from traditional analog to techy digital styles. Battery life is pretty decent. Even with frequent workouts using GPS, I average about two weeks before I have to charge the watch. In fact, I often forget about it until the 10 percent reminder comes on. The watch is stylish and good-looking, but still tough, well-made, and pretty much perfect for my needs. The buttons and touch screen are very responsive (the main button also rotates to move through the app drawer), the vibration is enough to wake me up from sleeping, I don't go crazy with outdoor workouts, so this is right for my needs. I know Amazfit makes more rugged watches for real adventurers, but they don't have all the features the GTR 4 has, so I'm happy I chose this watch. The Zepp app has gotten even better and has so much information and functionality. I found a lot of helpful videos online to help me with navigating the app; but, in general, I picked up on it pretty quickly, and have used it to customize the watch so it works well for me. Overall, I'm so happy I purchased this watch. Normally, I don't gush this much over a product, but I'm just so please with it. Amazfit makes really good watches that work well, last, and provide so much for the price point (way more, in fact). I highly recommend this product and Amazfit in general. I hope this review has been helpful.

An Amazing watch. Would buy again. Battery lasts forever (It seems)
I was looking to replace my Garmin VivoActive 3. It was a good watch, but a bit sluggish and the battery life had begun to fade, so time to move on. Looked at the current Garmin options and they either seemed like there wasn't much change or were super expensive. Friend told me to consider Amazfit. Wasn't quite sure what to expect, but decided to get this as I wanted to find a watch with smartwatch functions and decent battery life. BETTER THAN EXPECTED!! I got the gray band with black case was surprised how useful the band was. I wanted a black case, so this was my only option. I was able to link the Zepp app with Strava and Google Fit. With everything, there are always pros and cons. So to start with the bad: CONS: Zepp app isn't' bad, but it's a bit confusing. See below for some tips. Setup: Be prepared to spend a bit of time setting up the watch to your liking. Custom charging station. But you charge so infrequently, its not a big deal but it's the same with Garmin, Fitbit, and Apple. PROS: The battery life is insane. It's a bigger watch so I'm sure the battery is bigger, but I've worn it for 4 days now and am at 72%. And that's even after I've gone on two 6mi runs with GPS which is a battery hog. GPS: Picks up within seconds and kept the signal without interruption. Display: Big and good resolution. If running in sunlight, may need to turn up brightness though. The touch screen is very responsive and no lag. Puts my Vivoactive 3 to shame. Wrist tilt: My Garmin Vivoactive was hit or miss if the screen would turn on with my wrist tilt. The GTS nails it. Zepp App This app is necessary to communicate with your phone and maximize its smart watch functionality. It is also a pretty robust fitness app. The app is pretty thorough, but the layout isn't the most intuitive so expect to spend a little bit of time, especially in the beginning going through all the menus. It's similar to the Garmin app, but again, a bit less intuitive. If you want to link Strava, Google fit, etc, tap on "PROFILE" right lower corner, then ADD ACCOUNTS. A few tips: In the upper left is the watch icon. Tap on this to access the watch specific menu. Tap on NOTIFICATIONS AND REMINDERS to customize what you want to be alerted about. I turned off the standing and goal notifications and activated the app alerts for my important apps as well as incoming SMS WATCH FACES is self explanatory. You can buy new ones, but I found the preinstalled ones to be just fine. The APP STORE is meh. No apps such as Spotify, banking, etc. But I don't use my watch to buy things anyway. WATCH SETTINGS: I customized my LONG PRESS UPPER BUTTON to do the remote camera shutter, but you can pick what you want from a long list. I made my PRESS LOWER BUTTON access workout. I turned off MORNING UPDATES as I didn't find this useful. You can also change order or add/remove options on your watch using the EDIT QUICK ACCESS APPS and the EDIT CONTROL CENTER options. I got rid of a lot of stuff and moved up things like music control, and compass. You can also adjust your voice control options to suit your liking. I don't personally use this so I turned it off. APP LIST MANAGEMENT - adjust as you like. Can change order or remove items by sliding them. SHORTCUT CARDS - similar. APP SETTINGS - self explanatory. Under the PHONE option, you can MANAGE SMS REPLIES and can customize them. Useful if driving for example and you need to send off a quick prewritten reply. MUSIC you can actually store some music on the watch. I access it on my phone, but if you are someone who wants to have music and leave your phone behind, this can be useful to bring some tunes with you. ALEXA. It has Alexa. Pretty nice. Then the usual 'FIND WATCH" options. I turned off discoverable and heart rate sharing. Not sure why you'd want someone else to access this, but perhaps if you have a personal trainer? Under LAB, you can set up your remote camera shutter options. Unfortunately, you can't see what your viewfinder is seeing through your watch. You can only fire the shutter.

Very nice smart watch but why have one?
I've had this for several weeks now and this is my first smart watch experience. This one works and looks great and has great battery life if you set it up right. The heart rate is accurate, the steps are fairly accurate. The sleep info is nice.( I wish it had an ekg and blood pressure function. That would be info I'd like to have) The notifications work well. I don't like that can't really answer messages from fb or texts. They have a few pre made canned answers you can send back but you have to use your phone to answer properly. The other functions like music etc. Work fine also. All in all its a very nice watch. The faces variety seem limited. I don't use all of the excerise functions so I can't speak on those. I've resisted getting one for a long time because I really didn't see the point of having one if you have your phone nearby anyway. I stand by that even more now after getting one. Although it's handy to let you know about messages and you can answer a call if you're in another room than your phone, if you keep your phone on your person all the time like I do, it's really unnecessary. I have my phone in my pocket all the time pretty much. I don't do athlete training or heavy exercise which these things seem to be heavily aimed at. It does have it's good qualities and everything it does, it does well but the question is why do you need it? My phone does all of this stuff and does it better. So I guess if you leave your phone in another room a lot, this could be useful or if you train or excerise a lot. Or if you're not in a hurry to answer a message with other than a canned message like yes, no, OK etc. And like I said, you can answer a call with it as long as you are close enough to your phone. I think the range is around 30-40 ft. So, all in all, it does work well within it's limits. But smart watches in general seem more like a fashion accessory than a super useful tool in my opinion. At least for someone like myself who keeps their phone on them all the time like i do. But if you are an athlete or a person who exercises or trains a lot, I can see that this could be very useful to you. Or if you leave your phone in another room a lot, this might be useful for you also. As a watch it works fine too but you can get a much less expensive watch or use the time function on the phone. So for me, it was a totally unnecessary purchase other than just curiosity about what they actually do and how useful it really was (which in my case really was not very much) but I can see how it could be for certain people.

A competent, attractive fitness watch.
Update: I’ve now owned this watch for 3 months. Still doing great. Not a scratch on the face, and I’m pretty rough on my watches. Battery holding strong. I’ve become more attached to this watch than I ever was ti my Apple Watch. Very happy with my purchase. Original review: Let me preface my review with the fact that I’m a iPhone user. I’ve had most revisions of the Apple Watch and I’m not a fan. I think they’re blocky, poorly designed and not masculine. So I’ve tried many different watches over the years with varying success. I loved the Samsung watches until they became incompatible with IOS but their battery life was terrible. So I decided to give this watch a try. I was considering buying their more expensive military fitness watch for $400, but after comparing features and aesthetics, it was hard to justify the extra expense. So let’s talk about this watch. First, it’s shockingly light and has a really big, bright watch face. It’s also very thin. It fits very comfortably on my wrist. I wear my watch upside down so the fact is on the underside of my wrist. As such, the face is much more prone to scratches. I’m happy to report that after more than a month of use, not a single scratch is visible. The watch has a protruding dial button as well as a recessed button, in addition to the touchscreen. I rarely use the recessed button but the crown button is handy, but I wish it didn’t protrude as much. Sometimes when I curl my wrist, it powered off the watch. I’ve made small adjustments when I wear it, and it seeks to have resolved that issue. The watch face is very bright and incredibly responsive. The battery is astonishing. Ilas you set up the watch, it lets you know if you’re selecting an option that drains the battery faster. I’m a power user, so I pretty much have everything maxed out and I still get about 6 days battery life. I was also concerned, as per reviews, that the readings are inaccurate, especially the sleep readings. I’ve found them to be quite accurate. I spent two days with my Apple Watch on one wrist and this watch on the other. The readings were within 1% consistently. I’m pretty sure they’ve resolved many of the issues via upgrades to the watch. I feel this watch gives me much more usable information than does the Apple Watch and I really like the companion app. It is very intuitive and works well with my phone. Overall I’m very happy with this watch. Not only is it a steal for the price, I would choose this over the Apple Watch. Be aware That you cannot receive iMessages on this device. It’s a restriction from Apple and not the fault of this watch. As long as you connect this via Bluetooth, you can carry out most functions between your phone and watch that you would normally expect. My only complaint is I purchased the version with brown Watch band. The band is terrible and cheap. A poor choice considering how nice the watch is. Fortunately there are several cheap alternatives in Amazon so I won’t complain too much. Just be aware you’ll want a different band. You really won’t go wrong buying this watch for features, quality, functionality, aesthetics and price.

Very full-featured, works amazingly well, stunning battery life
I have been exceptionally impressed with this watch. All the advertised features work as promised (rare!) and the app is easy to use with almost all the data collected, processed, and displayed in very thoughtful and intuitive ways. And it collects so much useful data - far more than most fitness trackers. Battery life is unreal - I collect every available metric every 5 minutes 24 hours a day, consult it dozens a times each day, have the screen on full-time during all workouts, and it still lasts a week+ between charges. I scanned all my grocery-store, gym, etc. membership cards into the app and now I don't have to carry any of them with me - they are all on my wrist. It has made a huge difference in my fitness efforts due to the motivation that comes from being able to precisely track what you accomplish. There are some small issues that I would like to see improved: The app features annoying adds for add-on services (like more detailed sleep analysis) that require subscriptions. You can't turn them off either - they just come right back. It also includes an app store where you can buy watch faces and apps for a few dollars each. This is frustrating because almost all of them are available to download free from miwatchfaces(dot)com - they are reselling other people's free work and charging for it. My only other gripe is that the only Heart Rate Variability measurement function is a metric called "stress" with an arbitrary number that is provided after every measurement. This makes it difficult to interpret for one of the most useful ways of using HRV which is identifying when you are coming down sick a few days before you actually get symptoms. Also, why does that app consume so much background data??? But don't get me wrong, there are very few purchases I have made this year that have been as positively impactful and valuable. This is a great watch.

Extremely capable watch for the price
This is my second Amazfit watch, having previously owned the Bip U Pro model. This is a significant upgrade over that model and I am extremely happy with the purchase. Battery Life - 5/5: I have had this for about 10 days now, and a single charge has gotten me through. I am using this thing fairly often throughout the day and interacting with it quite a lot as I get to know its bells and whistles. The battery is very strong! Screen - 5/5: The screen is also quite bright on this watch. I have had no problems getting a clear read from it, even in bright and direct sunlight. It also gets quite dark at night, and the adaptive brightness is fairly responsive. Tracking - 4/5: So far, it seems to track activity, heart rate, and sleep reasonably well, but its not without hiccups. For example, it gave me a sleep score of 94/100 last night, and I can say I did not sleep very well in reality. I can't say that others are inherently better, but it is a drawback. The heart rate tracking can be sporadic, but I also tend not to wear it super tightly so that is naturally going to reduce the accuracy. Workouts do track fairly well when I use it, and the GPS works nicely for tracking runs. Comfort - 4/5: So far, the comfort has been reasonably good. Again, I can't say I have owned an apple watch or other competitor to use as a reference point, but the band has been pretty comfortable and I have not gotten any rash or anything that can be common with these sport bands. I will say wearing it a bit looser does prevent moisture from becoming trapped, so that likely has helped. Aesthetics - 4/5: Overall its a nice looking watch. I don't love the red dial, but otherwise it looks nice! As a 6'4 male, the size is an advantage, but for smaller frames I could see it being too large. Customizability and App Companion - 4/5: The Zepp app largely works quite well, but it can be a bit confusing to navigate. I have not had a great chance to use the coaching, so cannot comment on that just yet. The watch faces available aren't bad, but I will say they aren't all the prettiest. Some are quite a lot nicer, but others look like a 12 year old could have designed it. But that said, there are plenty of options that run the spectrum, so you shouldn't ever feel limited by that. Overall - 5/5: The price is great, the functionality is really good, battery life is impressive. There may be some marginal drawbacks, but this is a GREAT smartwatch at a great price.

Fix sleep tracking
Updated 1/21/2023 I have reduced 4 stars to 3 stars, just to motivate the company to look into my review and take an action. But in all honestly, this is a 5 star watch. I have seen and used lots of smart watches including big brands, this one from Amazfit is better than all. I have not seen a better looking and sleek smart watch. Some highlights. (1) I wear it 24/7, it's just that good that I don't want to take it off my wrist. I have Apple watch as well , that I bought a few years ago, but only used it a few times. Mainly because it's not good looking and not fun to wear, and the battery is almost a day or less. Now back to Amazfit. All the features work well. The auto sports modes (there are several workouts that automatically start when you start that workout. For instance, outdoor walking or running , cycling, swimming etc. If it' s not starting for you automatically, just change the sensitivity from 'standard' to 'high' under "Watch settings -> Workout --> Workout Detection --> Sensitivity --> 'high' ". This is through the Zepp App. Talking about Zepp App, good, precise, to the point, and very well designed, intuitive. There are several watch faces available for Free in the App Store. I have downloaded about 3 dozen faces, and all of them are designed by "Zepp Health". So all of those are official. And all are free. Just keep searching for faces and there are hundreds of faces that are free. I just stick to the "Zepp Health" faces. Beautiful faces, for every design/occasion. Just love it. I keep my watch in Always On Display to ON (in smart mode). This means that when I got to sleep, the watch automatically turns on the sleep mode and goes to silent/sleep setting and display turns off. I also track sleep breathing quality and blood oxygen. Works good. With all this activity, the battery lasts for me about 10 to 12 days. My guess is that if I stop sleep tracking, the battery would last a little longer. Overall, best looking smart watch, intuitive menu on the Watch, and well designed Zepp App. Sleep tracking is little off in Zepp 2.0 OS, I ask Zepp to fix it please. If I have to advise Zepp for future enhancement, I would say design 'body energy' meter. Something that can track body energy and recommends/predicts the level of energy in the body, based on last a few days of sleep, activity, etc. I know this is a lot to ask, but there are some that are doing it. for instance, Garmin high end watch has a feature like that, and Citizen CZ Gen 2 watch, about to be released Mar 1, 2023, would have a feature like that, which used NASA and IBM labs technology to monitor body energy levels and recommends on hour much it think you can go more before taking a break or rest or nap. May be this sounds too fancy, but as the time progresses, people are trying to be more aware of their body/surroundings/health, and this may be a thing of necessity and usage in near future. Zepp; you are doing an amazing job. Keep it up. Looks like some level headed and smart/people with common sense are running this company. After I see an update to the Zepp 3.18.1.1 software version on my GTR4 watch, I shall change my review to a 5 star review :) By the way, there are other Zepp watches that are so elegant and well designed. I bought a few of those as well for family. One is Zepp E Circle (Moon Grey) and (Ice Blue) . I would have bought Zepp Z Smart watch, as it's so traditional and elegant looking, but since it does not have Bluetooth call function, therefore, I didn't buy it. I bought t-rex 2 as well for outdoors. it was so well designed and reminded me of Casio G Shock, but I returned it as it did not have the bluetooth call function as well :( and was running older Zepp OS 1.0 Original review: Good watch. May be best looking smart watch in market. Zepp app is good. Battery life is about 10 days for me with moderate usage, and that includes always on screen all the time and sleep tracking every night. It runs latest Zepp OS 2.0. This OS is better than Zepp OS 1.0, but with one major issue. Sleep tracking is hit and miss and not accurate. With any Amazfit Watch running Zepp OS 1.0, sleep tracking is very accurate , as compared to an Apple Watch. But with Zepp OS 2.0, they software team has broken the algorithms. May be they tried to make it fancier by providing sleep schedule etc, but the underline functionally does not work properly. Please fix it

Great inexpensive smartwatch
The Racetrack Gray band is simple and is the most comfortable watch band I've owned. It's not bulky like some bands. Battery life has been fantastic for me. I only charge every 7 or 8 days. Maybe a bit more frequently when running with GPS tracking. The Zepp app works fine. No credit card is mentioned or required for installation. Not sure what a previous reviewer is talking about, no credit card is requested. Workout transfer to Strava works and is seamless. The only software problem I encountered was that Bluetooth pairing was a bit trial and error with my Samsung S22+. For proper phone control of texting, notifications and call answering the paired device must be of the form "Amazfit GTR 4-4D90". Without the last four alphanumeric digits the watch will not have proper phone connection for all functionality. It took me quite a bit of trial and error with disable/reenable of bluetooth and forget of "Amazfit-4" connection before the proper "Amazfit 4-XXXX" connection appeared. After this difficulty I've had no problems with connections at all. Hopefully this will be fixed in a future software update or better instructions. There are over 200 free watch faces selectable in the Zepp app. In the "Watch Faces" screen select the right clover leaf like symbol and all the free faces appear first. I do wish the default always on faces included a simple digital face but the analog ones are fine. The watch seems pretty sturdy but I do use one of the snap-on conformal covers (Wugonguan brand 3 pack) when working on my car or doing dirty yard work. Without expensive sapphire glass I'm pretty sure the screen will scratch if scraped on a rock. Maybe someday I'll splurge on an $800 Apple Watch Ultra but the Amazfit GTR-4 is the perfect first smart watch for me.
