On-Device 6-Stem Separation
OffgridStem
Separate vocals, drums, bass, piano, guitar, and more into 6 stems from any track — entirely on your iPhone. No uploads, no server queue, no subscription.
What it does
OffgridStem separates a track into 6 stems — vocals, drums, bass, piano, guitar, and other instruments — entirely on your iPhone. No data is ever uploaded to a server.
OffgridStem uses on-device machine learning to split a track into individual stems. Whether you're pulling an acapella for a remix, making an instrumental for practice, isolating a specific instrument to learn a part, or prepping 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
How many stems can OffgridStem separate?
Six: vocals, drums, bass, piano, guitar, and other instruments, all separated in a single pass.
Does OffgridStem work without an internet connection?
Yes — all separation happens on-device, so it works fully offline, including in Airplane Mode.
Is my audio uploaded anywhere?
No. Nothing is sent to a server as part of processing. See our Privacy Policy for details.
Does OffgridStem require a subscription?
No — OffgridStem Pro is a one-time purchase of £24.99, not a recurring subscription.
Does OffgridStem collect any user data?
No. The app is built without the networking code needed to send recordings or usage data anywhere. A self-conducted network audit (August 2026) found no outbound connections from the app during a full workflow test — full results on our Privacy Policy page.
How much does OffgridStem cost?
Free to try with limited separations per month. Pro unlocks unlimited separations and higher-quality exports for a one-time purchase of £24.99.

If you handle recordings that need to stay confidential, OffgridScribe transcribes and summarizes audio the same way — nothing ever uploaded. And OffgridCam (currently in TestFlight) brings the same principle to home and baby monitoring.
