Why bit by bit?
It actually adapts to you
Most apps give you the same program everyone else gets. bit by bit builds your plan around your goals, your fitness level, and your equipment. Performed well? The next session gets harder. Had a tough day? It dials back. Your plan evolves with every workout.
Built for calisthenics progression
Can't do a pull-up yet? The app starts you with dead hangs and scapular pulls, then builds through rows and negatives until you get there. Every skill has a progression chain — the app knows exactly what comes next, but you're always free to swap in something you enjoy more.
Adapts to your equipment
No bands? No problem — the app swaps in alternatives you can do. Only have a pull-up bar? It builds around that. Tell it what you've got and every workout fits your setup. No gear required to start, but a bar goes a long way if pull-ups are the goal.

The story
Built by someone who needed it
I started calisthenics with no idea how to progress beyond basic push-ups. Every app I tried either gave me the same generic program or wanted $30/month for a coach. So I built the training app I wished existed — one that actually understands bodyweight progressions, adapts to how you perform, and doesn't charge a premium for personalization.
