Support
Changes is in active development ahead of its beta. If something isn't working, you have a question, or you've got an idea, reach out. A real person reads every message.
Get in touch
Email jamey@warrenlabs.com and we'll get back to you. For bug reports, the details below help a lot.
Requirements
- Device
- iPhone (iPad supported; a Mac version is in progress)
- OS
- iOS 27 or later
- Cost
- Free during the beta. At launch, a one-time Pro unlock ($19.99; $14.99 for beta-list members) adds MIDI/Logic export, PDF sharing, and unlimited saved projects. No subscription, never per song.
- Network
- None required. Changes works fully offline
Joining the beta
The beta is distributed through Apple TestFlight and is gated on the public release of iOS 27. To get in line, join the beta list with your email. When the beta opens, we'll send a TestFlight invitation.
How to accept a TestFlight invite
- Install Apple's free TestFlight app from the App Store.
- Open the invitation link we email you, on the iPhone you'll use.
- Tap Accept, then Install, and Changes appears like any other app.
Reporting a bug
When something goes wrong, email us with as much of this as you can, since it speeds up a fix:
- What you did, what you expected, and what happened instead.
- Your device and iOS version (Settings → General → About).
- Whether it happens every time or just sometimes.
- If it's about a specific chart, a short description of the recording (instrument, rough key/tempo), no need to send the audio, since it never leaves your phone anyway.
During the beta you can also send feedback straight from TestFlight (take a screenshot, then tap Share → TestFlight).
Common questions
Does it need an internet connection?
No. Changes listens and writes the chart entirely on your phone. Nothing is uploaded.
Covers or original songs?
It's built for your own songs. A hum or rough take gets harmonized into a chart. It isn't a cover-detector.
Is my audio uploaded anywhere?
Never. No upload, no account. Your recordings stay on your device. See the Privacy Policy for the full picture.
How do I get my chart into Logic Pro?
Export a MIDI from Changes and open it in Logic. Run Analyze to get a Chord Track, then add Session Players that follow your changes.
How do I leave the beta list?
Email jamey@warrenlabs.com and we'll remove your address.
Privacy
Your music and the charts you make in Changes stay on your device. Read the full Privacy Policy.
