How offline mode works
Capture data without signal, sync when you're back.
Updated 22 Apr 2026
Offline mode
CanvassIQ is offline-first. The mobile app stores everything locally first, then syncs to the server when a connection is available.
What's stored offline
- Your assigned area and all addresses within it
- The active survey definition
- All responses you capture during your shift
When sync happens
The app attempts a sync:
- Every 60 seconds when online
- When you tap Sync now in the app menu
- Whenever the app comes back to the foreground
What if I lose my phone?
All in-progress data is uploaded as soon as the app reconnects, so a lost or broken device only loses the responses captured since the last successful sync — usually under a minute.
