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:

• 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.
