About this app

Band together to improve your fitness by competing in a group challenge. Enlist friends, family, teammates, colleagues, or whoever, to become gym rats. More effective than a simple step challenge, the goal is to workout more often; any activity counts.

-How it works-

* Create or join a group challenge
* Invite as many people as you'd like
* Post workouts to the group
* Keep doing that, a lot
* See leader board and have fun competing

-Flexibility-

The app is free form and allows for creating your own rules of competition. Score by total number of workouts, miles, minutes, calories, steps, or come up with your own point system. All that's required for a workout is a photo and a title. The photo can be of the gym equipment, a sweaty selfie, a screenshot of another app, or whatever your group deems acceptable.

-Accountability-

Don't care about score? No problem, the app can be used as a general group activity log. Keep each other accountable by having a shared space for tracking workouts.

Looks okay so far. A little basic, but that's really all we need. My only complaint is that when I link urls to workouts on youtube or tiktok, it doesn't show up as a link, and there doesn't seem to be any way to copypaste from what other users have typed. That really defeats a lot of the purpose for us.

Very nice app! just missed a feature to start a session and then closing in the app, using it as a check-in and check-out from workout, also as a stopwatch instead of having to track the duration of your training by yourself and then adding all at once

i cannot even set up my account. I can upload my picture but cannot type my name in as the keyboard is not popping up. Tried restarting my phone, the app, uninstalling the app and reinstalling...
