 `ios/` is a SwiftUI port of the Android app with the same features, plus CarPlay (browse tabs, Now Playing with Vocals and Mix buttons) and Siri ("play X in Stemify"). iOS 17 or newer.
 
+On top of the Android features: the Save chip in the mixer remembers a mix for that song and puts it back every time it plays, and the mic button turns on karaoke mode (vocals muted on every song, synced lyrics from [LRCLIB](https://lrclib.net) on Now Playing; tap a line to jump to it).
+
 Build an unsigned IPA on a Mac with Xcode and xcodegen (`brew install xcodegen`):
 
 ```
 cd ios
-scripts/build-ipa.sh      # writes build/Stemify.ipa
+scripts/build-ipa.sh      # writes build/stemify-<version>.ipa
 ```
 
-Sideload `build/Stemify.ipa` with Sideloadly or AltStore, which sign it with your Apple ID. To work in Xcode instead, run `xcodegen generate` and open `Stemify.xcodeproj`.
+Sideload the IPA with Sideloadly or AltStore, which sign it with your Apple ID.
+
+To get updates in AltStore, SideStore or Feather, add this source:
+
+```
+https://git.iamchrisama.com/cdnutter/stemify/raw/branch/main/ios/source.json
+```
+
+After uploading a new release (tag `ios-v<version>`, asset `stemify-<version>.ipa`), run `ios/scripts/make-source.py` to regenerate `ios/source.json` and commit it. To work in Xcode instead, run `xcodegen generate` and open `Stemify.xcodeproj`.
 
 CarPlay and Siri need the `carplay-audio` and `siri` entitlements. A free Apple ID can't sign those, so on a free sideload the app works on the phone but won't show up in CarPlay or Siri. A paid developer account covers Siri; CarPlay audio also needs Apple to approve the entitlement for your team.
