On-Device Stem Separation
OffgridStem
Separate vocals, drums, and instruments from any track — entirely on your iPhone. No uploads, no server queue, no subscription.
Download on the App StoreWhat it does
OffgridStem uses on-device machine learning to split a track into individual stems — vocals, drums, bass, and other instruments. Whether you're pulling an acapella for a remix, making an instrumental for practice, or isolating a stem for mixing, the separation happens right on your iPhone.
Why on-device
- No upload time — processing starts immediately, nothing leaves your device
- Works fully offline, including in Airplane Mode
- Unreleased or client work never sits on someone else's server
- One-time purchase — no monthly subscription for occasional use
Pricing
Free to try with limited separations per month. Pro unlocks unlimited separations and higher-quality exports for a one-time purchase of £24.99 — no subscription.
Frequently asked questions
Does this work without an internet connection?

Is my audio uploaded anywhere?
No. Nothing is sent to a server as part of processing. See our Privacy Policy for details.
Do I need a subscription?
No — OffgridStem Pro is a one-time purchase.

If you handle recordings that need to stay confidential, OffgridScribe transcribes and summarizes audio the same way — nothing ever uploaded.
