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)
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!
Works great

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

Pretty good, does what it says.
Working like a charm

It does a fantastic job in two-way syncing. A potential improvement I’d hope: Remove the need for Google Drive permissions if i choose to backup on icloud. I’m definitely less comfortable sharing access to my drive than tasksFeature request: supporting syncing with multiple google accounts.
Developer Response
Thank you for your feedback. We completely understand the concern around Google Drive permissions and privacy.To clarify, the app only requests the App Data permission. This means it cannot see, access, or read any of your existing files or other data stored in Google Drive. The app can only access files that it creates within its own dedicated app data folder.Google also explains exactly what this permission allows during the OAuth authorization process. You can view these details by tapping the small information icon next to the requested permission.Protecting users’ data and privacy is very important to us, which is why we deliberately use this limited permission rather than requesting access to your Google Drive files.
Bug fixes:
• Clearing a due date in Reminders now clears it in Google Tasks and prevents it from reappearing after sync.
• Clearing notes in Reminders now clears them in Google Tasks.
