Built for Strength athletes and CrossFit users who need to flip between multiple lifts/sets while timing rest periods and logging performance data mid-workout..
“Why can’t you use the timer while flipping back and forth between lifts/sets? It also doesn’t save the reps/notes if you flip back to the main screen…”

Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
Strength athletes and CrossFit users managing multiple lifts with rest timers and performance logging. No search volume data; competition 5/10 suggests some players exist but room remains.
Competition & the opening
Strong, JEFIT, Fitbod exist but lose timer state or data when users flip between exercises. The gap: persistent background timer that survives navigation and auto-saves reps/notes without manual sync.
What's hard to build
Keeping a timer alive in the background while the app navigates between screens requires Android/iOS background task management, database sync resilience, and avoiding OS kill-offs due to memory pressure. Feasibility 7/10 suggests solid engineering but not trivial.
Why now
Fitness app UX is fragmented; persistent overlay timers + state persistence are technically trivial but widely missing despite high user demand.
