The Backpocket mobile app is built with Expo 54 and React Native, designed from the ground up with an offline-first architecture. It provides nearly full feature parity with the web app, plus mobile-specific capabilities like share sheet integration, haptic feedback, and swipe gestures.

Tab navigation

The app is organized into four tabs:
TabDescription
HomeDashboard with recent saves and quick stats
SavesFull save list with search and filters
CollectionsBrowse and manage collections
SettingsProfile, appearance, offline, public space

​
Share sheet integration

The fastest way to save on mobile — share from any app:
1

Find content in any app

Safari, Chrome, Twitter, Reddit, YouTube, Instagram — any app with a share button.
2

Tap share, select Backpocket

The system share sheet shows Backpocket as an option. Tap it.
3

Instant save

The URL is saved with auto-extracted metadata. Haptic feedback confirms the save.
The share sheet works even when offline. Saves are queued locally and sync when you reconnect.

​
Swipe actions

Swipe on any save for quick actions:
DirectionAction
Swipe rightToggle favorite (star/unstar)
Swipe leftArchive or delete

​
Haptic feedback

The app uses subtle haptic feedback for key interactions:
  • Saving a link
  • Favoriting/unfavoriting
  • Archiving
  • Pull-to-refresh completion
  • Swipe action triggers
This gives the app a tactile, native feel that enhances the user experience.

​
Pull to refresh

Pull down on any list to sync and refresh your data. The app shows a native pull-to-refresh indicator and syncs with the server.

​
Deep linking

Backpocket supports the backpocket:// URL scheme:
  • Links shared from the app open directly in Backpocket when installed
  • Deep links can navigate to specific saves, collections, or settings
