Ohms Rehearse.
Slow, transpose, analyze, and loop the hard bars without uploading your song or opening a microphone.
Coming in version 1.2.0From one hard bar to target tempo
Set a real A–B loop, choose starting and target tempo, step size, repetitions, and count-in, then pause or resume at any point. Completed playback loops advance the ladder and factual history records only what actually played.
Available todayIt tells you when it isn't sure
Every detected chord carries a visible confidence, and low-confidence chords are hedged, never faked. Activate any chord by pointer or keyboard, choose its root and quality, and the source-visible correction stays in your local library.
Available todayNo microphone, no network, no account
Your song files and your practice sessions never touch a server, which is exactly why the app can be bought once instead of rented.
Drag any song down to a quarter speed to learn a fast line, or nudge it up to push yourself, and the pitch stays put. Transpose ±12 semitones independently to play in your key or simulate a capo.
On-device analysis lays the song's chords along the timeline and estimates its key. Low-confidence chords are visibly hedged; pointer or keyboard activation opens a root/quality picker and saves your correction locally.
Name a loop, set start and target tempo, step size, repetitions, and count-in, then pause, resume, or stop. Playback-loop completions advance the ladder; the app never claims to hear a clean pass or a mistake.
Export your on-device chord timeline as readable text or standards-compatible ChordPro with timestamps, confidence notes, and your corrections. No lyrics, tabs, or copyrighted song catalog are bundled.
The original CC0 Practice Ladder sample follows the same copy, decode, chord-analysis, library, and playback path as a file you import.
Bundled two-stem separation splits vocals from accompaniment on-device so you can mute a part and play along. It is not used to estimate the chord timeline.
