The app was locked to portrait in app.config.js and the hand-kept AndroidManifest.xml. Android 16 ignores that lock on screens 600 dp and wider, so tablets and foldables rotated into layouts that were never tested. This removes the lock in both places, keeps React state across rotation and split-screen resizes (`smallestScreenSize` joins `configChanges`), and fixes what broke in landscape: - the thread pager sizes its pages from its own width and snaps back to the open message after a rotation instead of showing half a neighbour - compose and the thread view share one keyboard tracker; a rotation with the keyboard open closes it, since Android sends no new keyboard frame and the old portrait one blanked the whole landscape composer - in a short window with the keyboard up the composer hides the format bar and tightens its header so a few lines of text stay visible - inputs with suggestions or context around them opt out of Android's full-screen landscape keyboard - month views fit whole rows to the real height, keep the month across a remount, and the month dropdown re-measures and caps its height - the week grid's header follows the remounted list after a rotation - the event sheet's actions stay on screen in landscape - every RN Modal allows all orientations, or iOS forces portrait
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.
Try it
- iPhone and iPad: join the beta on TestFlight: https://testflight.apple.com/join/rumcjNSp. A new release shows up there once Apple has reviewed it, usually within a day.
- Android: download the APK from the latest release.
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 or App Store listing yet: Android is a sideloaded APK, iOS a TestFlight beta (see Try it)
Run locally
