Tempo

Tempo is an iPhone app that lets you lock selected apps—such as TikTok, Instagram, or games—and requires physical activity to reopen them. It reads workouts from Apple Health, Apple Watch, Strava, and other fitness sources. The app uses a single balance of earned minutes. While the balance is positive, all blocked apps stay unlocked; the balance ticks down as you use them, and iOS automatically re‑locks everything when it reaches zero. There are no per‑app timers to manage. Tempo keeps all data on the device—no account, no server, no ads. The free version includes the core loop, one blocked app, and 60 minutes per day. Tempo Pro adds unlimited apps, custom caps, widgets, and full history, with a 7‑day trial available.
