節拍倒數 : 懸浮計時器 & 節奏提示

Beat Timer keeps a countdown floating on top of any app — no more switching screens when timing matters. FLOATING WINDOW (PiP) Set your target, tap Start, swipe away. The floating window stays visible above any browser or app. TARGET COUNTDOWN Pick any date and time. When the moment arrives, it flips to a count-up so you always know how far past the mark you are. BEAT INTERVAL Choose a rhythm from 0.33 s (182 BPM) up to 15 s. A haptic and sound fire on every beat — perfect for walking cadence, slow jogging, strength sets, interval training, or plank holds. PAUSE & RESUME Tap the floating window to show playback controls. Pause freezes the beat interval; resume picks up exactly where it left off. SIRI SUPPORT Say "Start Beat Timer" to launch the floating window hands-free. BUILT FOR FOCUS No clutter. Set your target, choose your rhythm, and get back to what you're doing. Beat Timer stays out of your way and shows up when you need it.
