iFertracker Smart Fertility Tracker

Does not work as the app will not let u sign in

Would give 0 if i could. App doesn't work, contact them and they ignore you. Do not buy

- read bad reviews still decided to use, alongside CB monitor and cheap OPK better than spending twice the amount on digital temp monitors that only measure oral or vag in morning- after TTC for 9 months I wanted accurate data, was sick of unreliable oral BBT results. The last thing you need to do is be continually putting effort into interpreting questionable results- I sometimes move or cuddle my husband before I wake, and I like to pee or drink when I wake, all ruining oral BBT and with iFertracker I can do all these without it affecting my BBT- $150 even with the $40 for 60 sticky patches is value for me to know my O day exactly and it predicted O day 2 days before- my cheap Easy@Home OPK was positive on ovulation the day before my temp rose, plus I had ovulation pain, the next day iFertracker showed a steep BBT rise confirming ovulation- my ClearBlue monitor predicted first peak day 1 day after cheap OPK and iFertracker making the ClearBlue monitor uselessI have experienced some of the issues bad reviews mention, however I was able to fix them:- battery was fine after 30+ days of use- I had an error one night and was upset I didn’t get a BBT, however I did not know that the iFertracker stores the last 10 nights of BBT, the next night it worked fine and I got previous day BBT- a second time I had an error for 3 nights in a row, worried I was near O day I took out the battery and put in a new one (no notification it was low) and it still had error, and then the app froze while trying to connect to the tracker even after close-reopening the app. - I then disconnect tracker from app, deleted the app, reinstalled the app and it was still frozen, I kid you not. I wore it again that night and it worked the next morning with all the missing nights informationMy experience in depth:Prediction Feature not advertised, but very useful!I’m not sure why this device isn’t advertised differently, it doesn’t aim correctly at women who want this for BBT for fertility. This feature should be advertised! Even if it works better for some than others. I hadn’t even read about it in the book or online.I forget what data is initially entered, I think it's only average cycle length and start day.I started using it on d3 (cycle day 3) last day of my period, my temp dropped significantly and remained low until O day. The 3 very low temps puzzled me, however I check my calendar (I record sleep, drinks etc) and found those 3 days I had unusually late nights (only 3-5 hours sleep), was up hours later than usual, and ate a lot more sugary food and meat (I usually don't eat meat or sugar) which seem to disrupt my sleep. This accounts for the lower temps, in fact in the manual it says you need to wear the device for 4 hours, I cheated and slept for 3 hours then wore it an hour awake so I could get a result. I would say that’s so you know you get into deep sleep, the same kind of sleep you have on other nights so you can actually compare accurately.I could easily see the steady decrease in temp and the device came up with a prediction 2 days before my O day that my O day was in 2 days! I was very surprised that it was accurate, I didn’t know about this feature. Are you using a good algorithm? Any machine learning? That would really be an excellent way forward to increase the uniqueness of this product, help with interpreting and predicting BBT and the relation to phases in a woman’s cycle. There would be a great way to offer something that us currently not being offered in any other fertility product.One other note about the sticky patches:I tried what I thought was a good double sided tape to reduce the cost of matching patches, it left so much sticky residue on it. The patches used to come off cleanly and easily.Before thinking about the type of plastic this product is made from I used a little natural nah polish remover to get sticky residue off and although it worked I ruined the glossy finish of the product, not that I care about the looks but then it made the double sided tape stick even more. I ordered the matching patches and now they stick, instead of coming off super easy. I would suggest just stick to the expensive patches!Improvements for Developer- BBT Chart has date but not the cycle day- problem freezing- no combined shipping for patches is annoying fro those who have long cycles, 1 pack does not do 2 cycles for most women, especially if we put some on wrongSalesYou could really do a lot more to sell this tracker in a more personal, informative way. It sells as cold, distant, medicalised - when my own use of it has been good, though only because I am excellent at interpreting the features for myself. For the average woman I can see how they are not using this well, or getting the help and support they need.Please hire a woman who has been through infertility, and has personal experience in knowing how the average woman needs help to use the device, app, and interpret.Average people do not have the best analytical skills and with some help I could see many women getting help with their cycles for fertility making a huge difference. Now that’s a market for more profit and the better product.

**UPDATE: All of my review still stands, but I found some ways to make use easier by buying the batteries and adhesive elsewhere. I think this unit comes with the cheapest battery in existence (quality) because I have bought other brands on Amazon and they last months. I bought the type of adhesive tape that is used to stick to clothing and to your skin to hold clothes in place. They are very cheap (priced) and work a lot better than the ones they recommend you use on the product. Since I have found batteries that last and adhesive that works and doesn't cost an arm and a leg, I am much happier with the product.Pros: small, lightweight, sticks well without falling off, app helps you pinpoint your cycle with amazing precision.Cons: I've used it for about two weeks and the battery is already too weak to sync to the app. The adhesive leaves a very mild, but annoying rash(that goes away quickly. I alternate which side I wear it on and that helps). I'm afraid that if it's linked to my phone overnight while attached to me I'll be getting radiation, which is a very scary place to get it (armpit/breast area) However, I don't know that it's the case; it just worries me. There is a way around it: turn off Bluetooth on your phone while it's on you, but that gets annoying to do all the time (constantly turning it off and on each day) The replacement adhesives are beyond ridiculously priced on here so I'm going to try to use double stick tape.Overall, I think it's too overpriced for what it delivers.

UPDATE: My initial tracker was replaced because it would have a dead battery daily. Great.But now, after 3-ish weeks, the new tracker will not connect. I have done all the obvious steps to try and remedy this such as changing the battery, deleting and reinstalling the app, verifying my bluetooth is operational, restarting the phone, restarting the app.... nothing is working and I haven't been able to connect for 3 days. This device is extremely frustrating to say the least. When it does work it is great. But for having only owned the item a little over a month and have already had it replaced and now the new one isn't working... it just seems like a lot of hassle. It is not reliable.The monitor is easy to use and so far seems to be working great! Was easy to sync up and the app seems to be okay. Very simple, but easy to use.Two stars for the abysmal battery life. I've had the monitor not even a week and am already on my 3rd battery, That is ridiculous. Would be a far superior product if it was one that had to be recharged.

I wasn't sure what kind of performance I would get with this, but I have been pleasantly surprised.I have never been a morning person, so temping first thing never really worked out for me. This has worked out great. I peel the thermometer off when I wake up and sync it while getting ready.Other reviews touch on this as well, but the native app is basically only good for getting the temperature off of the thermometer. It looks simple enough, but I can't figure out what half of the buttons are for... I would definitely use a separate app for charting - Kindara is a great free one for both Android and Apple.Battery life was a big concern from the other reviews. The battery life on my thermometer has been great - I keep my cell phone's bluetooth off during the night and only sync the two in the morning, so I think I'm getting extra long battery life... I actually managed over two weeks on the battery that came in the package. Even then, it still worked, I was just nervous that it would run out during the night. When putting it on for the night, you do need to wake it up, so to speak. I just squish the sensor against my arm to wake it. I did notice that as the battery got older, it took a little longer to start. Before I changed the battery at two weeks, it would take around 30 seconds of pressing the sensor to my skin before it would light up. Changing the battery, or using my husband's (hotter) arm seemed to help. I guess it shuts down until it reaches a certain temperature.The stickers that hold the thermometer are kind of awful. I've run into a couple in the package that didn't hold their stickiness and had to immediately replace them. They leave a sticky residue on your skin when you pull them off, and if you wear it in the same spot repeatedly it will irritate your skin. I need to pick up a replacement pack, and they are kind of expensive for what you are getting. I may give double-sided tape a try instead...I have pcos and really wanted to understand what was going on with my cycles. Just charting for one month has already shown me a great deal of information. This was a fairly expensive device, and it's not perfect, but all in all I'm pretty happy with my purchase.

Update: It croaked. This worked for the one cycle it worked for and I got pregnant and put it away. We started to TTC again so I got it out again and it is worthless. It has been eating through batteries and it will not connect. The little blue light hardly lights up. The app can’t find the iFertracker anymore. It’s worn out and it was not hardly used but for half a cycle until I realized I was pregnant. I mean honestly it was totally worth the $100 I paid to get my son here four years ago. But it’s pretty lousy that it only worked for that one time. I really want another baby so I’m debating ordering another one. Update 8/6/15: I got my BFP (positive pregnancy) test the first month of using this. Some tips: The rash eventually goes away..it's as if your skin gets adjusted to it. Keep fresh batteries and switch them out every 10-15 days. They're actually EXTREMELY inexpensive here on Amazon. Also, use another app to input the info that ifertracker reads. Ifertracker still needs some work on their app. I suggest one of the ones listed below. I will definitely be using this again when it's ttc again. My OB was really impressed with my bbt chart. Update: The adhesive will leave a rashy mark on your skin. Each battery lasts about 5 days not 30-60 as the manufacturer states. And if your battery is fine when you go to sleep, it could very well be dead when you wake up thus making the recorded BBT impossible to retrieve. This is ridiculous.Packaging: the iFertracker bbt thermometer came packaged in the same packaging shown in the picture. Inside the package were very basic introductions, a battery, a battery compartment opener and 30 stickers to affix the thermometer to your body.Merchant: I originally purchased this from Raiing in the Amazon marketplace and was charged $10 shipping in addition to the $149.99 for the thermometer. I knew this before I ordered it but the thermometer sold from Amazon with free shipping was sold out. The shipping charges were refunded, however, even before the charge for the iFertracker was withdrawn.Product: the ifertracker is approximately 2" long and 1" wide. It is very small, very light and could probably be lost extremely easily. I would recommend putting it back in the packaging after each use to prevent this or possibly using a small drawstring bag or something similar. The battery compartment was easy to open with the included tool and the battery was simple to load. I did this and then downloaded the app which I will discuss in a moment. When it was time for me to sleep and use the iFertracker, applying the adhesive patch was simple. It is a double sided sticker with a hole cut out for the iFertracker's temperature sensor. I affixed the patch and then applied it under my arm. I did not apply it directly in my armpit but shortly below it. I think that if you apply it directly to your armpit, the patch adhesive may not stay stuck throughout the night due to maybe deodorant residue, etc. I was worried and checked often when I would wake throughout the night but I had no problems with the iFertracker staying attached. It was still there when I woke up. It was also very easy and painless to remove, which I did upon waking before syncing with the app.Phone/tablet app: I have an iPhone 6 and I downloaded the app ahead of using the iFertracker so I wouldn't have a delay in syncing. The app feels very archaic and clumsy. There are many spelling errors and the prompts include very 'jerky' or broken English. This product was made in Japan so I can somewhat understand. There is no way that I am able to find to change between US and metric measurements for weight and height so I would have to google that info first and THEN enter it. I was concerned at first due to this, that there was no way to switch from Celsius to Fahrenheit for bbt tracking but thankfully I did find this and was able to switch easily. You are able to record intercourse, alcohol intake, ovulation pain, disrupted sleep, only 3 types of cervical mucous when there are regularly about 5, emotions (16 to choose from), ovulation testing, pregnancy testing and symptoms (16 to choose from)..none of these are quantifiable or user editable. I would like to see updates that would allow these to be editable or maybe a sliding scale from mild to severe, similar to Fertility Friend, Glow or iPeriod and many other apps. Also there are places to record your daily weight (again, only in metric units) and medicine taken or any illness for that day. When you remove the iFertracker to sync, all you need to do is open the app and place the iFertrackeron top of your screen. When it is complete, a bubble will pop up with the recorded bbt. It's extremely simple.Currently, I am only using this device to record my bbts because due to sleep schedule, I have a hard time getting a consistent result. I've only used the iFertracker one night and I think it works well, so far. But I have just been inputting the temp result into one of the apps I mentioned above which are much more comprehensive across the board at tracking all fertility factors and anything that may have an affect on your menstrual cycles. I hope that Raiing reads these reviews and follows up with updates to their app at minimum. I really do appreciate the product because I haven't seen anything else like it so far as this is the first all night wearable bbt thermometer. I would like to update my review as changes/improvements are made.
