PAID ยท $4.99

Bout

A pay-once interval timer for HIIT, Tabata, boxing rounds, EMOM, and fully custom work/rest patterns

Fitness interval timers are one of the worst offenders in the subscription economy โ€” a screen with a number counting down, gated behind a monthly fee. Bout does exactly what you need mid-workout and nothing else: build any work/rest pattern, run it on a full-screen color-coded display readable from across the gym, and never see a paywall again.

$4.99, once, on iOS and Android. That's the whole pitch.
