Read full description

Cadence Sync is a precision interval metronome designed to guide your training sessions, track your BPM, and maintain an exact cadence through crystal-clear audio and visual cues, synchronized in real time with your Apple Watch. Whether you need to structure high-intensity interval blocks or hold a steady rhythm, Cadence Sync projects clean audio tones and dynamic visual indicators without interrupting your background music or podcasts. Key features: • Precision interval metronome: Custom interval blocks with target cadence (SPM/BPM) and duration, featuring smooth 10-second transition ramps. • Real-time heart rate tracking: Stream sub-second heart rate (BPM) measurements directly from Apple Watch sensors via HealthKit. • Dynamic visual flasher: Electric cyan and emerald green glowing ring guiding your movement timing and recovery phases at a glance. • Pure synthetic audio engine: High-definition dual-frequency tones (440Hz, 880Hz, 800Hz, and 350Hz) engineered to cut through background music without spoken voice overlays. • Seamless background audio mixing: Play your favorite playlists on Spotify, Apple Music, or Podcasts in the background while Cadence Sync overlays metronome tones. • Test mode & HealthKit sync: Easily toggle between saving completed sessions directly to Apple Fitness & Health or discarding them in test mode. • Privacy first: Your health metrics stay 100% on your personal devices. We never store, transmit, or share your data with third parties. Master your rhythm with Cadence Sync.
