Stemora
Read full descriptionHide full description
Stemora splits any song into 6 separate instrument tracks -- drums, bass, vocals, guitar, piano, and other -- right on your device. No internet required, no files ever leave your phone. AUTO METRONOME THAT FOLLOWS THE DRUMS Stemora listens to the separated drum track and places every click right on the hi-hat and snare -- no tapping, no guessing the BPM. It follows live recordings whose tempo drifts, counts 6/8 songs the way musicians do, and stays in time when you slow the song down. Prefer to set it yourself? Switch to Manual and enter your own BPM and start point. HOW IT WORKS Import any mp3, m4a, or wav file from your library. On-device AI (no server, no upload) separates it into 6 clean stems in minutes. PRACTICE & MIX - Mute or solo any instrument to isolate what you want to hear or practice along with - Adjust playback speed using the automatically detected tempo, without changing pitch - Shift pitch up or down by semitones - Set A-B loop points to repeat a tricky section - Built-in metronome locks to the song's actual beat, not just a fixed click - Download your custom mix (e.g. the song minus guitar) as a single audio file to practice with anywhere PRIVACY FIRST Separation runs entirely on your device using Core ML. Your music is never uploaded anywhere. FREE TO USE Separate your first 2 songs for free. Need more? Watch a short ad to earn additional separation credits -- no subscription, no in-app purchase required. Perfect for musicians learning a song part by part, singers wanting an instant karaoke track, producers studying a mix, or anyone curious what a song sounds like without the vocals. Note: Please only use Stemora with audio you own or have rights to use. Separated stems are intended for personal practice, learning, and rehearsal.

Verdict
The clearest difference is in-app purchases: Stemora at none against Chord Studio's 2. Stemora also leads on iOS requirement (16.2 vs 26.0). Chord Studio's advantage is ads (none vs shown) and device support (3 vs 1). On price and update cadence there is nothing between them.
