System Overview

What Refrain does

Refrain turns any track into a practice tool. Drop start (A) and end (B) markers anywhere on the waveform, loop the tricky bar until it's yours, then save it as a named segment to return to instantly. A count-in lead-in eases you in; bookmarks and per-track markers remember where you left off. It runs fully offline: your audio and settings never leave your device.

  • A/B Loop Markers, Saved Segments & Bookmarks
  • Interactive Waveform Navigation & Snippet Preview
  • Precise Skip, Count-In Timer & Background Playback
  • Offline & Private: Zero Data Collection
