This year Amazon has been flooded with fitness trackers offering wrist-based heart rate monitoring. While I like the Fitbit ecosystem they are a lot of money for what they are, and it is a high price to pay if you are just getting into fitness.
I bought this particular tracker is the design is nice and it is considerably cheaper than the Fitbit HR2 at a bargain price of just £33.99. It also has some additional functions such as blood pressure (which I was sceptical of).
On my wrist it is quite a nice size, I have slim wrists, and it isn’t too large on it. The overall build quality feels pretty good, but the way it is made means you won’t able to change the strap is that breaks, at this price I don’t suppose that is a major concern. It charges via a proprietary cable which fixes itself to the watch with magnets, and I found the magnets quite weak so that a slight knock will disconnect the cable.
It was a little confusing setting up, there are no buttons on it at all, and it seemed unresponsive even after charging a bit. After a full charge, it seemed to wake up, and I was able to set it up. In order to wake the screen, you can move your wrist or tap the very lower portion of the screen. It took me quite a while to realise this.
The app for the tracker is not hosted on Google Play, and you must download the APK and then install it after enabling unauthorised apps. The app requires a disturbing number of permissions including being able to record audio and view all your messages. This is presumably for the notifications, but I found that I didn't receive any notifications during my use. The number of permissions required and the fact it is an unverified Android app is a big issue for me.
The blood pressure readings are very inaccurate. It would generally say my pressure was 110/70 which is very healthy, in fact, it is 129/72 when tested properly. Not a huge difference but one reading is on the high end of normal while the other the low end.
The actual heart rate and step counting seem about as accurate as most other trackers.
Overall, my main issue is with having to download an APK to install the App then accept a large number of permissions. If this were hosting on Google Play, I would be far less sceptical. Due to this issue, it is not something I would personally recommend using. If you are not overly concerned with privacy issues, and just want a cheap fitness tracker, then this would work perfectly fine.
