Like a fellow reviewer, since beginning of August (the last software update) I have not been able to pair the polar app with the heart monitor. I've had the polar H7 since nov. 2016, with no issues with pairing and using the app. Around August it stopped working. I've tried new batteries, uninstall and reinstall the app, turning the phone off and all the trouble shooting tips on the polar support site and online tips. I upgraded and got the polar H10, thinking that the monitor H7 was old. But it is doing the same thing with the app. Just red spinning circle, never paring.
Cool app idea (and the only way to use polar heartbeat monitors), but super buggy. Syncing happens sporadically at best. Unclear what is done in this app vs polar flow (I think both are required to sync to most places?). Syncing has to often be undone/redone.
Just changed the battery a week ago, and it's not syncing to the app? What gives? Been working fine for damn near a year and all of a sudden the battery is low. 2 stars until the app is updated. This HRM isn't a year old.
Inaccurate gps and poor customer support. I have the app automatically upload data to strava. I took a 46 mile bike ride. Polar shows it as a 14 mile ride but strava, using the same data properly shows it to be 46 miles. I contacted customer support. They told me strava uses it own calcations and left it at that. That is obvious. Strava uses the correct calculations. But polar didn't seem to be interested in fixing their calculations.
Update (8/30/17): I use this for all my strenuous activities (a couple of hours a day). I finally replaced the battery. It hadn't died, but was "low". Occasionally, it won't pair but a phone reset fixes it. I wish it had a step tracker or integrated with one. I use it with my treadmill because I found the treadmill heart rate monitor unsatisfactory. Update (3/30/17): It's actually quite good for real time heart rate monitoring (I use the H7) and calorie tracking during workouts. For H7 battery life you probably don't want to wear it except for workouts. To connect to MyFitnessPal you need to use Polar Flow. Beat syncs to Flow syncs to MFP. Workout editing could be better; you can edit distance and add a workout note. Once you've closed a session you can't edit the distance any more. You should be able to add/edit a name so you can track workouts of the same basic types but with current focus areas, e.g. Upper body vs Abs and core. Overall, this is a good app. I'm getting a NordicTrack 1750, which, as far as I know, is not compatible with Polar Beat or the H7, so I won't be using it for treadmill. I'll still use it for other workouts and hikes. And, I'll still use my Garmin vivosmarthr+ for all day tracking. It would be nice to have one solution that provided all day tracking plus accurate heart rate for workouts but I haven't found one.
It doesn't allow you to customize heart rate zones. You must buy one of their rate monitoring watches to do this, and even then, you still can't download the custom heart rate zones (available in sports profiles in their watches) to the polar beat app. I'd be willing to pay for the feature, as a pro version or something, if only they offered it... other companies app's let you customize heart rate zones, but then their total calorie count is wrong. Why can't we have both accurate calorie count and customizable heart rate zone (I.e. sport profiles) in an app from polar? Crazy that they haven't met this simple need....
