## What is gtsync?

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

A seamless way to keep everything you need to do synchronized across both platforms. gtsync securely connects Google Tasks to the 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.

Sync and organization
• Bi-directional sync between the Reminders and Google Tasks apps
• Sync reminders in the native Calendar app and tasks in the Google Calendar app
• Sync titles, notes, completion status, and due dates
• Discover and match task lists and reminder lists
• Choose which lists are included
• Automatically include new lists if you want
• Create a missing list automatically when needed

Review and resolve changes
• See pending creates, updates, and deletions before applying them
• Review the direction, list, timestamp, and changed fields for each item
• Compare both versions when an item changed in both services
• Choose whether to keep the Google Tasks or Reminders version
• Optionally resolve conflicts automatically using the most recently modified version

Automatic and on-demand sync
• Optional background sync takes care of staying in sync
• Use the Siri Shortcuts action to sync on demand, in an automation, or when you open a task app
• Get notified about conflicts and other issues that need your attention

Safety and visibility
• Configurable safety threshold for large batches of automatic changes
• Automatic sync pauses when the threshold is exceeded so you can review first
• Activity history with sync actions, errors, and timestamps
• Progress indicators and the ability to stop an in-progress sync

Statistics
• Day, week, and month views of your sync activity, with quick navigation between periods
• At-a-glance totals for items synced, completed, conflicts, and errors
• Activity chart showing creates, edits, completions, uncompletions, and deletions over time
• Breakdowns by direction, action, and list
• Tap any breakdown to see the matching entries in your activity history

Privacy
• Sync processing and sync history stay on your device
• Connects directly to Reminders and your Google account

Limitations
gtsync syncs titles, notes, completion state, and due dates between Reminders and 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)

### 5/5 — 👍

*2026-08-27*

Pretty good, does what it says.

### 5/5 — What I was looking for

*2026-08-22*

This is exactly what I was looking for—a way to sync my Apple Reminders and Google Tasks. This automated sync makes keeping it all together easy. I wanted to leave a review because I hope the developers will keep providing services. I paid and downloaded it because I saw that the most recent update was only a few days ago. Thank you devs!

### 5/5 — Works great

*2026-07-18*

This does exactly what I want it to do with minimal fuss. I use an iPhone so Siri uses Apple Reminders, but I also use a Chromebook and want to sync my tasks to Google Tasks. This allows the best of both worlds. I can manage tasks in either application and they are synced across platforms. I originally attempted to automate via IFTTT but this is so much cleaner and simple. Well worth the very reasonable price

## Version history (last 5 releases)

### 1.10 — 2026-08-25

Improvements:
• Minor improvements to the Settings screen.

### 1.9 — 2026-08-17

New features:
• The Activity log gained a search field — search titles, notes, and previous values, with matches highlighted and a preview snippet showing where a hit came from.
• The Activity log gained Action, Direction, and List filters, shown as dropdown menus that indicate how many options are selected.
• Text in the Activity log, change detail, and task detail screens can now be selected and copied — including selecting part of a value's text, not just the whole thing — and links inside task titles and notes are tappable there.
• Tasks assigned to you via Google Chat or from a Google Doc now sync into Reminders — previously they were skipped entirely. Docs-assigned tasks include a short note explaining that gtsync manages their description (Google Tasks doesn't support notes for these tasks) and a link back to the source, both kept in sync automatically; the link is also saved to the reminder's URL field on iCloud and on-device lists, so other apps can read it. When gtsync restores a note that was edited elsewhere, that shows up in the Activity log as its own "Restore" entry. Updating triggers a one-time catch-up sync, so tasks that were already assigned to you before the update aren't missed.

Improvements:
• The Activity log tells you when it's showing fewer entries than actually exist, instead of silently hiding older ones.
• Backup and restore screens show "Unknown size" instead of a misleading "0 KB" when a backup's size can't be determined.
• The "Detecting Changes" overlay text no longer repeats itself.

### 1.8 — 2026-08-03

New features:
• Moving a task between lists in Google Tasks, or a reminder between lists in Reminders, now syncs as a move to the matching list on the other side — with the previous and new list shown side by side on the Changes and Activity screens — instead of being deleted and re-created.

Improvements:
• Redesigned the Changes and Activity detail screens: each changed field now has its own row, with word-level highlighting showing exactly what changed in a title or notes edit, and a summary sentence alongside the relevant timestamps under "Details".
• List and conflict rows on the Changes and Activity screens now read as a short description of what happened (for example, "Edit notes for Buy milk"), with the sync direction shown as a caption.
• Completing or uncompleting an item is now described as "Completed" or "Uncompleted" instead of the generic "Status changed", combined with any other field that changed at the same time.
• Timestamps on the detail screens are now grouped under a single "Last Changed" label, one line per service, with a tap-to-explain info button describing what "Last Changed" and "Last Synced" mean.
• Enlarged the Apply button on the Changes screen and gave it an "Apply" label for VoiceOver (it previously announced as "Play").
• Changed the "No actions matching filter" message on the Changes screen to "No changes matching the filter".

Bug fixes:
• Moving a task in Google Tasks into a list you haven't turned on syncing for is now treated the same as deleting it — the matching reminder in Reminders is removed, and moving the task back re-creates it — instead of leaving a stale reminder behind forever. The same now applies to a reminder moved into an unsynced list in Reminders.
• Completing or uncompleting an item that also had a content edit, such as its notes, now shows that edit as a full before/after comparison on the Changes screen instead of only the new value.
• Notes containing only whitespace no longer show up as a false change on the Changes screen.

### 1.7 — 2026-07-22

New features:
• New Statistics tab shows your sync activity by Day, Week, or Month, with summary tiles, an activity chart, and breakdowns by direction, action type, list, and issues — swipe or jump to a date to browse other periods, and tap a breakdown to see the matching entries in the Activity log.

Improvements:
• Sync action colors (create, update, complete, uncomplete, and delete/error) are now distinct and consistent across Changes, Activity, and Statistics.

### 1.6 — 2026-07-18

New features:
• Added a Notifications section to Settings showing whether notifications are enabled, with a button to turn them on or a link to System Settings if they're off.

Improvements:
• Daily backups now also run after a manual sync or after a Sync Tasks shortcut run that gets paused rather than skipped, so backups stay current even if you rely on manual or Shortcuts-triggered syncs.
• "Sync Failed" and "Sign-In Required" notifications from background sync now appear at most once a day instead of repeating on every failed attempt.
• When another device is already syncing, background and Shortcuts-triggered sync attempts now show a "Sync Active on Another Device" notification naming that device, instead of a generic "Sync Failed" message.

Bug fixes:
• Fixed "Sync All" on the Changes screen silently doing nothing when syncing is blocked — it now shows an inline error like other sync failures.
• The Sync Tasks shortcut now reports a clear error (or fails quietly, depending on "Send Errors as Notifications") if its local data can't be opened, instead of failing unpredictably.
