About gtsync: Sync Tasks & Reminders

Two-way sync between Google Tasks (including tasks in Google Calendar) and the native Reminders app.

Finally, a seamless way to keep everything you need to do in one place. gtsync securely connects Google Tasks directly to the native Reminders app. Add a reminder using Siri on your commute, and it's waiting for you alongside your tasks in Google Calendar on your laptop. Check an item off in your browser, and it clears from your iPhone. One unified workflow, zero friction.

Core Sync
• Bi-directional sync between Apple Reminders and Google Calendar (including Google Tasks)
• Auto-discovery of your Reminders lists and matching Google lists
• Automatic list creation on the other side when missing
• Per-list enable/disable toggle
• Auto-enable new lists setting

Conflict Resolution
• Automatic detection when an item changes on both sides since last sync
• Manual resolution: side-by-side comparison with field-level diff highlighting
• Automatic resolution: keeps the more recently modified version

Activity Log
• Full audit trail of every sync action with timestamps
• Field-level change tracking (title, notes, status, due date)
• Auto-cleanup after 60 days (configurable)

Sync Triggers
• Background sync (Background App Refresh)
• Siri Shortcuts: "Sync Tasks" intent for automations

Safety
• Configurable threshold (10–1000): pauses background sync when pending changes exceed limit
• Warning banner in Changes and Settings screens when threshold exceeded
• Notification alert when threshold is exceeded

Privacy
• 100% On-Device Syncing: All data processing happens locally on your device. Your reminders never leave your phone.
• Zero Creepy Tracking: No third-party analytics, no ad trackers, and no data harvesting.

Limitations
• gtsync syncs titles, notes, completion state, and due dates between the native Reminders app and Google Calendar / Google Tasks. The following fields do not sync due to platform differences and limitations:
• Attachments
• Alerts / reminders
• Priority
• Recurrence (repeating tasks)
• Time-specific due dates (reduced to date-only values)

What's New in the Latest Version 1.1

Last updated on May 8, 2026

Old Versions

New features:
• Pick which Apple Reminders account new lists are created in, both during onboarding and later in Settings.
• New Siri Shortcuts setup guide with step-by-step screenshots, reachable from Settings under Background Sync.
• Cancel a backup restore while it's still in the safe phase.
• New app icon.

Improvements:
• Sync-lock retry button renamed to "Retry Without Taking Over" when a takeover is possible, making the choice explicit.
• Daily backups fall back to alternate destinations when the preferred destination is unavailable, instead of silently failing.
• Activity-log retention now defaults to on for new users, so the activity log self-prunes by default.
• Backups settings warn clearly when daily backups are off, when storage is set to Local only, and when reminders sync via iCloud (where backups can duplicate items on a fresh device).
• The Activity log view loads quickly even with very long histories.
• Backup imports accept both compressed and plain JSON files.
• The backup-action spinner now appears on the button you actually tapped.
• Restore overlay shows the current step (Preparing, Safety backup, Restoring, Finalizing), with the Cancel button emphasized and reliably tappable.
• The tab bar is hidden while a backup restore is in progress, so the restore can't be interrupted by switching tabs.
• Apple Reminders authorization refreshes when returning to onboarding or Settings from System Settings.
• The Apple Reminders source picker is hidden when only one source is available, and the wording around the "Automatic" option is clearer.
• Google sign-in stays valid longer near token expiry edges.
• Google Tasks list collection caches across launches, so list changes are detected faster on the next sync.
• Backup creation cleans up its temporary files even when it fails partway.
• Apple Reminders source picker stays visible when the previously selected account is temporarily missing, so it can be reselected.
• Google sign-in screen now explains why signing in with Google is necessary.

Bug fixes:
• Restoring a Google Drive backup during onboarding now creates the pre-restore safety backup it was supposed to create.
• Background sync no longer reads from the keychain when background sync is disabled.
• The activity log retention cutoff no longer drifts away from the user's chosen retention window.
• Backup app-version field shows "unknown" instead of a misleading "1.0" when it can't be read from the backup.
