## Description

Tempo SlowMo is a versatile practice companion that slows or speeds BPM without changing pitch. Designed for musicians, dancers, and language learners, it helps you work at your own pace. Import audio from iPod/Apple Music, Dropbox, or over WiFi, then play, pause, and adjust tempo from 20% to 250% with marker-based looping and easy export to MP4.

Apple Music tracks load for practice, though some controls aren’t available for those files. Core features include background playback, AirPlay, start/end markers, and looping; plus in‑app purchases for playlists with BPM lock, Pitch Changer, BPM Tapper, 10‑band EQ, Balance controls, and ad removal. DRM protected tracks are not supported.
