Cadence Sync

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 Wear OS
smartwatch.

Whether you need to structure high-intensity interval blocks or hold a steady rhythm in rowing, running, cycling, golf, or functional fitness, Cadence Sync projects clean audio tones and dynamic visual indicators without
interrupting your background music or podcasts.

Key features:

• Real-time heart rate tracking: Stream sub-second heart rate (BPM) measurements directly from Wear OS smartwatch sensors.
• 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 or YouTube Music in the background while Cadence Sync overlays metronome tones.
• Test mode & local privacy: Easily toggle between testing workouts on-screen or saving your session history.
