Focus on your workout, not the clock. LuckOut Timer is a simple work and rest interval timer for HIIT, Tabata, circuits, and everyday training. SET YOUR PACE Choose work and rest intervals from 5 seconds to 5 minutes. Start with a 3-2-1 preparation countdown on iPhone, then follow the large countdown and clear WORK and REST screens. TRACK YOUR SESSION See completed rounds and total work time at a glance. Pause when you need a break, resume when you are ready, or reset to begin again. Running and paused sessions restore when you reopen the app. CLEAR CUES Hear spoken cues while LuckOut is open. The iPhone screen stays awake during an active workout. A Live Activity displays the current interval on the Lock Screen and, on supported iPhones, Dynamic Island. APPLE WATCH Use the independent Apple Watch app to set intervals and run a timer from your wrist. Haptic cues play while the Watch app is active. The timer catches up when you return. Phone and Watch sessions do not sync. WHEN YOUR IPHONE IS LOCKED Go and Rest sounds require notification sound permission. LuckOut schedules up to 60 phase changes at a time; reopening the app replenishes them. Silent mode and Focus may suppress sounds. If the Live Activity shows Open Timer, tap it to refresh the current interval. Use Pause or Reset to remove the timer card and stop scheduled sounds. No account required.
