Sync with Dropbox

Use Dropbox to sync your own 2Do devices with the same Dropbox account. It carries task details and saved organization and works with older versions of 2Do that cannot use the recommended iCloud sync.

Dropbox sync works during Android's full-featured trial and requires 2Do Pro after the trial ends.

What Dropbox Sync Supports​

  • Task titles, notes, dates, alarms, repeats, priorities, stars, actions, tags, and location assignments.
  • Projects, checklists, and subtasks.
  • List groups, tag groups, Smart Lists, saved search rules, and sections.
  • A task's picture and audio attachment.

Dropbox uses one picture slot and one audio slot per task. Additional attachments and link-only attachments do not travel through this method. Manual order inside regular lists syncs, but the separate manual order inside Focus Lists requires iCloud.

Monthly Repeats​

Use the latest 2Do versions on all your devices for month-end, weekday, and weekend-day repeats. See Repeating Tasks for requirements and available rules.

What 2Do Stores in Dropbox​

2Do uses its dedicated app folder under Apps/2Do. The files are for 2Do to exchange sync data; they are not a task viewer you can use in Dropbox. Your connection to Dropbox is encrypted in transit.

Setup​

  1. Open Settings > Sync setup > Sync Method and choose Dropbox.
  2. Back in Sync setup, tap Link with existing account.
  3. Sign in to Dropbox and authorize 2Do.
  4. Return to 2Do, close Settings, and pull down on the task list to sync.
  5. If asked how to start, choose which side contains the tasks you want to keep. See replacement choices.
  6. Set up Dropbox on your other 2Do devices with the same Dropbox account.

For an additional device, choose Replace data on this device when Dropbox already holds your complete copy. Use Replace server data only when you deliberately want this device's copy to replace Dropbox's data.

Check the account before replacing data

Different Dropbox accounts keep separate data, even when both belong to you. Confirm the account used on each device. Make a backup from Settings > Manage Backups and share it off the device before replacing work that exists only there.

Daily Sync​

Choose an interval under Sync automatically. Android can delay background work; pull down on the task list to request a sync while 2Do is open. See Background Sync on Android.

Backups are separate from sync. Keep backups if you need a copy you can return to after an unwanted change has synced.

Common Issues​

Old or missing tasks​

Check the account first. Another Dropbox account may hold an older copy. Compare it with the device containing your current tasks before replacing anything. See Old or missing tasks with Dropbox.

"Dropbox Not Linked"​

Open Settings > Sync setup and use Link with existing account to authorize the correct Dropbox account again.

Dropbox v1_retired error​

Update 2Do from Google Play or our website. An old app version may be using a retired Dropbox API.

504 timeout / 509 bandwidth errors​

Check your connection for a timeout. For an error that asks you to wait or reports an account limit, let that restriction clear before syncing again. Repeatedly pulling to sync will not remove a provider limit.

Dropbox metadata reset​

If 2Do asks you to choose a starting copy again, confirm which side has the complete tasks. Make a backup before choosing a replacement; a reset is not a reason to assume either copy is current.

Different task counts on different devices​

Let sync finish on each device, then compare the same lists and view filters. If tasks are still missing, check the account and troubleshooting guide.

Setting Up Another Device & Troubleshooting​

Use the same Dropbox account and receive its copy on the additional device when it is complete. See Setting up a new device.

For a deliberate replacement later, use Settings > Sync setup > Next sync action. Choose Sync normally, Replace data on this device, or Replace server data, return and confirm, then pull down on the task list. The choice returns to normal syncing after a successful sync.

Privacy​

2Do uses Dropbox's app-folder access for its sync files. Do not edit, rename, move, or delete those files by hand. Changing them outside 2Do can break sync or lose data. Use Settings > Sync setup to change accounts or methods, and use Manage Backups to keep recovery copies.

To invite another person to one list, use iCloud list sharing. Sharing a Dropbox login or its 2Do folder is not that invitation process.
