User reviews

Overall pretty good

Provides what I need but it does not let you change your age if you make a mistake when setting it up. Which is annoying given that age is used as the basis for pretty much all of this. They also don’t respond if you contact them.

User Beware - Security and Privacy Issues

I have had several concerns and issues with this app over the week of my trial.

Most concerning is that after deciding to end my trial because of all the technical issues, I found that it does not have a log out option, a user account option, or a clear my data option.

The app pulls in fitness data from “integrations” but it doesn’t push.

The watch integration is non-existent. It only pulls data from an activity you run with the native watch app. So, if you are working out at the gym and don’t have your phone on you, but want to check your zones and points on your watch, you can’t.

After ending a workout and closing the apps the workouts continue to run on the background.

If you use any other fitness app or workout system, this app doesn’t sync any of that data. (Ex: strava, or f45, etc.)

Finally, I signed up for the trial, never selected to to be billed for the yearly subscription, and yet I was billed for the yearly subscription instead of monthly. No response from their support team.

Based on this, my guess is it was pushed live as a “get-rich-quick” tactic by the developers and then sells the data harvested. The developers are likely counting on you not noticing the $4 a month charge.

Garbage

For $6 a month this app stinks. Keeps freezing up while in use. No metrics for the fat burn percentage of calories. Click on the support link from the app details takes you to a broken link file not found.
