Contact Zones Support

I had high hopes for this app for delivering cues when training within customizable heart rate zones. Sadly, the Settings | Sync Now function does not work (always times out), so the Watch version of the app is stuck in its belief that my maximum heart rate is 185. Because of this error, the best this app can do is tap my wrist when I change between preset zones based on a max heart rate of 185. Not the customizable zones I was hoping for. The Watch version of the app does correctly send workout data to both the iPhone Health app, and the iPhone version of this app (so the sync error is not an issue with the Watch app talking to the phone)... There is apparently no option on the website (or in the app) to report bugs. Maybe the developers read one-star reviews and will provide support for the broken Settings | Sync Now feature...

It contradicts itself and doesn't agree with the health app. For example last week I went for a 40 minute run, a 3 mile hike, and a gym session. In the stats screen it records all of these activities, and if I look at the workout specifically I can see that my heart rate was indeed in zone 1 or higher for all of these, yet in the "time spent in zones" chart, it only shows 69 minutes in zone 1 and 0 in all others, even though when I add the workouts up manually, I have well over 150. And last week it showed about 25 minutes in zone 2 as well. I've also had it show 200+ minutes for the week on Friday afternoon, then when I go back and look at it the next day it drops to 60-80 something minutes. Basically this app is useless for me since I wanted to use it to track time in HR zones for training. Waste of money.

I am a user of this app who had upgraded to Pro. I do HIIT training about 4-5 times a week, and often have to restart in the middle of the my workout for freezing up and not registering my heart rate correctly. Then recently, it stopped transferring data from my watch to the phone. After restarting both iWatch and iPhone, I tried to delete the app and re-install. It lost all of my data. I contacted customer service and they referred me to an online faqs page of what’s supposed to happen when one tries to delete the app (2 prompts are supposed to show up, the second allowing you to keep your health data). However the second prompt never showed up for me and the app deleted after the first prompt. I tried deleting again as a sanity check since I absolutely do not remember that second prompt, and again it deleted the app after the first prompt. Now my last 6 months of workout data is gone. I guess not the end of the world in the greater scheme of things, but still frustrating that the glitches in the app keeps it from working as it’s supposed to. Will be utilizing a different app, as this one is obviously not trustworthy. 2 stars because it’s great when it actually works.
