Genius Plus vs CadenceSync

Genius Plus brings smart music discovery to your local library. It analyzes tempo (BPM), key & chroma, spectral centroid, and energy to create a compact feature vector for each track. Using a high‑performance approximate nearest neighbor index (HNSW), it finds sonically similar songs and builds seamless playlists and radio stations; on your device, privately. Tune the “feel” of your playlists in Settings. Emphasize chroma/key, tempo, or energy; enable dimensionality reduction (PCA) and optional quantization to reduce storage. Batch‑process your library, browse song details, and start a radio stream from any seed track.

Your music. Your pace. CadenceSync detects your live running cadence and automatically adjusts your music's tempo to match — step for step, pitch-perfect. No chipmunk voices, no warbling. Just your music, timed to your stride. Prefer a fixed target? Lock in a specific SPM and CadenceSync holds it there, mile after mile. Rhythm Intelligence Rather than blindly speeding up or slowing down, CadenceSync finds musically natural tempo variations — half-time, double-time — that meet your cadence goals while keeping the music feeling right. Built for the Road Runs entirely on your local music library. No internet, no cell signal required. Trail, track, or treadmill — it works wherever you do.
