Working offline
Create a manual list and add its first item without waiting for a connection. Accepted list and item changes remain available after an app restart. Reconnect and check pending changes before relying on another device having the latest copy.
ListAIse keeps locally available shopping data in its on-device store. Supported list-item mutations also enter a crash-durable queue before the app attempts to replay them against the cloud, so a brief connection loss or app restart does not discard those queued operations.
What This Means for You
- Locally Available: Open lists already stored on the device during a connection interruption
- Immediate Feedback: Supported item changes update the local list before cloud replay
- Ordered Replay: A new list synchronizes before its queued item changes
- Visible Status: A badge exposes pending in-app sync operations and opens a manual retry action
Technical Note
How Offline Mode Works
Understanding how ListAIse manages data offline helps you use the app confidently, even in challenging connectivity situations.
The Offline-Sync Cycle
Initial Data Download
Supported Item Operations
Change Queue
Connectivity Detection
Automatic Sync
Queue Clears
Sync Timing
ListAIse triggers the durable list-write drainer when connectivity returns and during app startup. When the app-bar pending badge is visible, tap it and choose Sync nowto retry the in-app pending operations immediately.
What You Can Do Offline
Offline support is strongest for lists already present on the device and for the item mutations covered by the durable pending-write queue.
Locally Available Lists
- ✓ Open lists already stored on the device
- ✓ Review cached items and completion state
- ✓ Search, filter, and sort local list content
- ✓ Continue a shopping session through a connection interruption
Durable Item Operations
- ✓ Add items to lists
- ✓ Check off items
- ✓ Edit item names and quantities
- ✓ Delete items
- ✓ Reorder or clear list items
- ✓ Update item prices
Prepare Before a Shopping Trip
Offline Limitations
Cloud-only work still needs a connection. Availability also depends on whether the required list data or on-device AI model was prepared before the device went offline.
Network-Dependent Content
- ✗ Recipe import from URLs
- ✗ Cloud AI requests, including the Assistant and ingredient substitutions
- ✗ Remote images and downloads
- ✗ Installing a missing on-device model
Installed on-device AI can have different offline capabilities from cloud AI.
Collaboration
- ✗ Real-time updates from others
- ✗ Inviting collaborators
- ✗ Receiving remote changes while disconnected
- ✗ Presence information from other shoppers
Supported queued item changes are reconciled after connectivity returns.
Account Operations
- ✗ Sign up / Sign in
- ✗ Password reset
- ✗ Email verification
- ✗ Account deletion
- ✗ Subscription changes
Authentication requires an internet connection
Queue Scope
Automatic Synchronization
When the device reconnects, ListAIse starts its sync orchestrators and drains supported durable list-item operations. Firestore also resumes its own pending work.
Sync Triggers
Synchronization automatically starts when:
- Network connectivity is restored after being offline
- The app starts and performs its cold-start drain
- You tap the visible app-bar pending badge and choose Sync now
What Gets Synced
Upload to Cloud
Supported queued item mutations, including add, update, check, delete, reorder, price, and clear operations
Download from Cloud
Firestore-backed list updates resume through the app's normal listeners once the device can reach the service again
Sync Status Indicators
Changes are currently uploading or downloading
A cloud-upload badge shows the in-app pending count
A cloud-off icon exposes an error and any pending count
Conflict Resolution
Shared lists can change on another device while your operations are waiting. ListAIse handles this reconciliation automatically; there is no manual "Ask Me" conflict dialog.
Changes to different items are synchronized individually, so renaming a list or editing one item does not replace another person's unrelated changes. Simultaneous edits to the same item can still conflict; check the result after reconnecting.
Recover pending changes
- Open the pending-changes badge and use Sync now or Retry when offered. Accepted changes remain saved across app restarts while waiting for recovery.
- If you lose edit access, the original shared list cannot accept your changes. Choose Save personal copy to keep the recoverable contents in a list only you own.
- Choose Discard pending changes only when you no longer need those unsynchronized edits.
- If local storage cannot accept another change, resolve the displayed error before continuing; an unsuccessful action is not a saved change.
Minimizing Conflicts
Sync Status Indicator
The indicator in a list's app bar reports sync activity, pending operations, or a sync error. It is not a general online/offline status bar.
App-Bar States
The shipped component has four visible behaviors:
Pending Changes Badge
When the in-app sync provider has pending work, the badge shows the operation count. Tap it to open the Pending Changes sheet and its Sync now button.
Scope
The current UI does not place per-item offline dots on modified rows and does not show a persistent "Online" or "Offline" label.
Offline Mode Best Practices
Follow these tips to get the most out of ListAIse's offline capabilities:
Pre-Download for Known Offline Periods
Before going somewhere with poor connectivity (flights, rural areas, basements), open ListAIse while online to ensure all recent data is downloaded and cached.
Regularly Sync on Good Connections
When you have WiFi, let the app sync fully before going offline again. This minimizes conflict potential and ensures you have the latest shared list updates.
Communicate with Collaborators
If you're about to make significant changes to a shared list while offline, let your collaborators know to avoid simultaneous conflicting edits.
Monitor Sync Status
If a pending badge remains visible after reconnecting, open it to review the count and use the shipped Sync now action.
Be Cautious with Deletions
Item deletions use the durable queue, but whole-list and other cloud operations do not share that same guarantee. Reconnect before destructive list-level work.
Troubleshooting Sync Issues
Occasionally, sync issues may arise. Here's how to resolve common problems:
Sync Stuck or Failing
If sync appears stuck or repeatedly fails:
- Check your internet connection (try loading a website)
- Open a list and tap its pending or error icon
- Choose Sync now in the sheet
- If that fails, restart the app completely
Missing Recent Changes
If changes from other devices aren't appearing:
- Verify you're connected to the internet
- Check that the other device has finished its own sync
- Reopen the affected list after connectivity returns
- If your pending badge is visible, open it and choose Sync now
