CadenceSync vs RND Shuffle

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. Stay in Control * Smart Shuffle draws from your play history to keep things fresh * View and manage recently played tracks * Export your full library as a CSV

Built by a jazz musician with too much music. The Problem: Standard shuffle lies to you. Ask Siri to "play some music" or hit shuffle in Apple Music, and you'll hear the same familiar tracks over and over. If you've got a big library, that's a waste. The Solution: RND Shuffle uses cryptographic randomization to generate playlists that actually feel random. You'll rediscover albums you forgot you owned. Features • Create custom categories by combining artists and genres — like "Jazz Piano" or "Workout Mix" • Exclude what you don't want — for example, 'no spoken word' or 'meditation' tracks in your music shuffle • CarPlay support for quick access while driving • Works with your existing Apple Music library RND Shuffle is free with no ads, no tracking, and no in-app purchases.  The source code is available on GitHub at https://github.com/benday-inc/AppleMusicPlaylistManager
