Linus Rath 23af324d79 fix: verify app updates without a second slow progress bar
Since releases ship an `.apk.sha256` file, every in-app update checks
the downloaded APK against it. The check read the 40 MB file in base64
chunks and hashed it in JS, which took longer than the download, and it
reset the progress bar to 0 under the "Downloading" label, so the update
looked like it downloaded twice, the second time slowly.

The file is now read and hashed natively through expo-crypto (the JS
hasher remains as a fallback), and the bar stays full under a
"Verifying…" label while the check runs.

Bulwark Webmail

Bulwark Mobile

Beta - work in progress. Many features are unfinished or rough. Expect bugs, missing functionality, and breaking changes between releases. Do not rely on this for primary email yet.

React Native (Expo SDK 54) client for Bulwark Webmail - a JMAP-based mail, calendar, and contacts app.

What works today

  • Sign in to any JMAP server (e.g. Stalwart)
  • Multiple accounts
  • Email list, threads, compose
  • Calendar (basic)
  • Contacts (basic)
  • Push notifications via the Bulwark relay - FCM by default, or UnifiedPush (e.g. ntfy) for devices without Google Play services
  • Android: contacts and calendars sync both ways with the phone's Contacts and Calendar apps (Settings → Contacts / Calendar → Sync to this device)
  • In-app sideload updates from GitHub Releases

What's missing or rough

  • iOS builds, but push notifications, client certificates and syncing with the phone's contacts and calendars are Android-only so far
  • S/MIME, plugins, themes - UI stubs only (filters & rules, the vacation responder and file storage are real implementations)
  • Calendar editing is partial; contacts editing is basic
  • No Play Store distribution yet (sideload APK from Releases); iOS ships via TestFlight

Run locally

npm install
npx expo start

Then press a for Android, i for iOS, or scan the QR with Expo Go.

For release APK builds and signing see docs/android-release.md. For iOS builds and TestFlight distribution see docs/ios-release.md.
