Daily Growth Challenge

Build strength one day at a time. Daily Challenge keeps you consistent with two complementary kinds of routines.

Daily rep challenges — push-ups, squats, pull-ups, anything you can count. Set a daily target that climbs each day (e.g., +1 rep/day), or stays constant. The app calculates today's number, breaks it into smart sets with rest periods, and tracks your growth on a progress graph.

Fall behind? It rolls into a deficit with a one-tap catch-up button. Finish early? You'll see the satisfying green "Done" badge.

Timed exercises — structured sets like physical therapy or mobility work. Configure something like 6 sets of 10 reps with a 10-second hold and 5-second rest. Hit Start Set and the app walks you through each rep with distinct haptic cues for "hold", "rest", and "done". Eyes on form, not the screen.

Apple Watch native — both kinds run right on your wrist. Tap reps for challenges, run guided timed sets with the screen kept on, swipe between exercises. Everything syncs automatically.
