Band together to improve your fitness by competing in a group fitness 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 the leader board and have fun competing


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.


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.

-Integrates with the Apple Health App-

GymRats has the ability to import workouts from the Apple Health app. This not only includes activities recorded on the Apple Watch, but any activity saved to your device.

What’s New

Version 34

* Fix automatically posting to multiple hustle points challenges, allow selection
* Allow decimals in points when editing an activity

Easy, simple, and fun

This is perfect!! I love how customizable this is. My friend and I are working out together but hated apps that made you weigh yourself and count calories. We just want to focus on moving and enjoying fitness, not worrying so much about obsessing over macros. We’ve been using this 3 weeks so far and it’s super motivating! I wish you could edit the photo after the workout is posted, though. It would also be nice to see the progress total—such as total number of minutes or distance or whatever goal it is. I’d love an option with a progress bar or percentage showing how far into the challenge you are too.

Either way—it’s nice there’s different options like hustle points, which we’re going to try next. PS for those who do want to track calories burned, you can have that option. It also has distance, time, and some other options, too! This is a great app.

Great app, perfect for our needs.

My friends and I have been looking for an easy way to do fitness challenges, but since we all have different phones/fitness trackers/preferred methods of exercise, this was proving hard to do. This app solves that problem nicely, and we rank by calories burned. My only gripe, and this is a personal one, is that I wish it linked to my Fitbit. Since it does not, I have to manually enter data, which is only mildly inconvenient. My other wish is that I would like the option to add photos or videos to all workouts, not just the manual entry ones. Otherwise, a perfect app for our purposes.

The perfect social fitness challenge app

I never leave reviews but I just love this app and I appreciate the responsiveness of the developer. My friend and I wanted to do a fitness challenge for fun and I researched every social fitness challenge app in the App Store, and after trying a bunch I picked this one because it has all the features I was looking for and nothing more. It's super simple and easy to use. Also, the developer Mack is super responsive, and I was pleasantly surprised that he immediately responded to some suggestions I gave. Thanks for taking the time to build, maintain, and improve this app!
