My device won't sync. How do I fix it?

Modified on Tue, 02 Aug 2022 at 08:17 AM

When Todo displays sync errors, it may be caused by a database update from a recent version of Todo Cloud 10, Todo 8, Todo 6, or Todo for Mac. You may notice sync problems in the following ways:


Tasks created on one device do not show up on other devices. For example, a task created on an iPhone may not appear in Todo for Mac. Marking a task complete does not show up on other devices.


Sync errors are displayed on the bottom status bar of Todo.

Note: If you are still using Todo 6, we recommend updating to use Todo 8, or Todo Cloud.


To get sync working again, you should take the following steps:

  1. Make sure you are using the very latest version of Todo or Todo Cloud.
  2. Choose the device with the current set of tasks. For example, if your iPhone has a complete, current set of tasks, but the Todo Cloud app on for Mac or iPad is missing some tasks, do a sync from the iPhone.
  3. Go to the other devices and do a sync reset. This will use the latest set of tasks.
  • Using Todo or Todo Cloud, tap Settings > Account > Reset Synchronization Data.
  • In Todo Cloud 10 for Mac/Windows, click on your name in the top left > click Sign Out > re-sign into your account.
  • On the older Todo for Mac app, go to Preferences > Synchronization > Reset.
