About this app
Rebase is a fitness challenge app where you compete with friends on workout goals. Create challenges, invite friends, set your personal goals, and track your progress together. Stay motivated by seeing your group's activity and cheering each other on. CONSISTENCY IS THE KEY Real results don't come from perfect workouts - they come from showing up, week after week. The hardest part of any fitness goal isn't the effort, it's the consistency. And the most reliable way to be consistent? Accountability with the people you care about. When your friends can see whether you showed up today, you show up. That's what Rebase is built for. WHY REBASE Most fitness apps are solo. Rebase is different - it's built around your friends. No anonymous leaderboards, no isolated tracking. Just you, your friends, and the goals you've set together. HOW IT WORKS 1. Create a challenge - pick a duration and invite your friends 2.

What’s New
One workout, every challenge. Log a session once and it counts everywhere you're competing — switch between challenges on any activity to see each crew's cheers and comments. Fix your logs. Edit the notes, date or photo on any workout you've already posted. Like comments. Cheer what someone said, not just what they did. Hosts get control. Change a challenge's dates before it starts, or call it off entirely. Rebuilt screens. A live countdown before kickoff, a redesigned end-of-challenge recap, and workout photos now in your notifications.
