Portable Ketone Breath Analyser | Track Metabolism, Ketosis, Low Carb Diets, Fitness | Electronic Acetone Test Stick, Bluetooth Connection to iPhone or Android App

After using the device, 9 out of 10 times the app does not complete the test procedure - the device or the app (I'm not sure which) simply "hangs". I wll be returning the device for a refund as it is not fit for purpose.

I’m really happy with my purchase, i’ve found it very accurate. You can get fluctuating readings based on how much oxygen you have left when the unit finishes the measurement. Once you get consistent I usually get within a few digits if I take multiple readings. I really like the app as well. So very happy with this purchase.

Meh after two or three uses shows the same

It helped me understand when I was in ketosis, on a daily basis and what foods helped.

This portable ketone breath analysers is very easy to use, it’s good quality and works well. No issues after couple of weeks using it daily

This portable ketone breath analyser by Acetrack is good, when it works, annoyingly the app keeps on disconnecting from Bluetooth meaning you have to start the process again. Its also rather pricey at £219.00 (price correct at the time of writing this review)I'm watching what I eat and cutting back on carbs, so I was intrigued to see how this machine would measure my ketone levels. To use it you will need to download their app and register, you'll also need to put in your height in centimetres (I had to Google mine as I'm feet and inches lol). You can register other users on the app, or they can download it to their phone and register, using the spare mouthpiece to measure their breathThe machine is really easy to use, with step by step instructions on the app, but it does take a while to load up, and then more often than not it disconnects from the Bluetooth and you have to start the process all over again which is really annoying but when it works, it's great, if they could fix the app then it would be so much betterMy ketone levels seem to change all the time, but at least monitoring them using this machine I can keep track and make sure I'm eating properly and you can record your levels on the app each time you use it, so this will helpThe machine has a USB charging wire and will need to be charged before useWith this machine being small and lightweight you can take it around with you to keep a check on your ketone levels throughout the dayWhen this machine (and app) works its great but a pain when it glitches. It's quite pricey and I'm sure there are similar devices available that are much cheaper too

Can't trust a device that produces wildly varying results in consecutive measurements as seems to be the case with this one. First time I tried it I got a reading of 23ppm, followed by 14 and 7. Just now I got 108, 86 and 121. That is a massive discrepancy and leads me to believe the measurements are completely inaccurate. I did the measurements one after the other, sitting at my desk to eliminate as many variables as possible.To use the device you need to install an app. Downloaded the app on my android phone and while it works, it is a bit buggy. I won't go into details here as not sure there is a point. Looks like it needs a bit more work.In short, this device does not seem to be giving consistent measurements and as such is pretty useless.

This monitor is lightweight and easy to take with you, I use the app and follows step by step, but sometimes you have to start the process over and over again, it just too much, not good enough for the price.
