Your offline practice room. Any song β†’ your speed, your key, no lead vocals β€” everything runs on your iPhone, nothing is uploaded, and it's completely free. REMOVE VOCALS β€” OR KEEP ONLY THEM On-device AI splits any song into vocals and backing. Practice with a clean instrumental, or solo the vocal to study the phrasing. Works with audio files and videos. SLOW DOWN WITHOUT CHANGING PITCH 50–150% speed with clean time-stretching. Step-Up Tempo raises the speed a little every loop β€” the classic way to master a hard passage. CHANGE THE KEY Β±12 semitones in real time. Session detects the song's key and shows you where your transposition lands. LOOP EXACTLY THE RIGHT BARS Drag precise A-B handles on the waveform, snap them to the detected beat, and save named sections (verse, chorus…) to jump between. EXPORT YOUR PRACTICE MIX Export audio β€” or the original video with your slowed, re-keyed, vocal-free mix, picture retimed to stay in sync. Save straight to Photos. PRIVATE BY DESIGN No account. No cloud. No upload. Your music never leaves your phone β€” and there's no monthly fee, no usage quota, no catch. Made by the developer of TakeCover Studio.
