You can view events from Apple Calendar next to your to-dos. If you are experiencing trouble with this feature, the following tips might help resolve them.

Things never imports data from Apple Calendar. It simply displays the data that Apple Calendar shares with it.

If what you see in Things is not correct, it means that Calendar sent faulty data to Things. We have no means of correcting this ourselves – the issue has to be fixed in Apple’s Calendar app.

Some events or calendars do not appear

Things depends on Apple Calendar to provide it with correct information about your events. If what you see in Things does not match what you see in Apple Calendar, Apple Calendar has sent faulty data to Things. Here are a few steps you can try to correct this:

  • Reboot your Mac.
  • Turn off calendar integration via ThingsPreferencesCalendar Events, then re-launch Things and turn calendar integration back on.
  • If you use Things Cloud (check if ThingsPreferencesThings Cloud is enabled) to backup your to-dos, remove Things entirely from your device, reboot, and then reinstall Things. Re-enable the calendar integration and check if the data comes through now.
  • Last but not least, you might want to try to remove your calendar accounts (especially with Google or Exchange accounts*) through System PreferencesInternet Accounts, reboot your Mac, and then add those accounts back.

* If your Exchange or Google account is being managed by your IT department, they might have set certain restrictions that prevent Apple Calendar from sending information to other apps. That’s a limitation we cannot circumvent.

iPad & iPhone

Basic troubleshooting

Only follow the steps below if you are using Things Cloud to backup your to-dos! Check that ThingsPreferencesThings Cloud is enabled.

  1. Tap and hold the Things icon on your iPad or iPhone.
  2. Tap Remove App -
  3. Reboot your iPad or iPhone (Don’t skip this step!).
  4. Install Things again.
  5. Go to ThingsPreferencesCalendar Events and enable the integration again.
  6. Connect to Things Cloud via ThingsPreferencesThings Cloud to download your data.

Depending on the size of your database, the download might take a little time. Please don’t close the app while this happening and make sure your iPad or iPhone is charged and has a stable WiFi access.

Advanced troubleshooting

If none of the above steps helped to fix the problem*, you might want to try to remove the problematic calendar accounts from your device and then add them back.

  1. Go to Settings app → CalendarAccounts and delete the accounts that cause trouble. Keep in mind that this will remove all the data for this account from your iPad or iPhone.
  2. Reboot your iPad or iPhone.
  3. Add the accounts back, check that the calendar data appears in Apple Calendar, and then enable the calendars again in Things.

* If your Exchange or Google account is being managed by your IT department, they might have set certain restrictions that prevent Apple Calendar from sending information to other apps. That’s a limitation we cannot circumvent.

Some Google calendars do not appear

Even though you can see all your Google calendars in Apple Calendar, you can’t select some of them in ThingsSettingsCalendar Events. As a result, some events aren’t shown in Things. This might happen specifically with subscribed or delegated calendars, and is a result of faulty calendar settings outside of Things.

  • Log into your Google account via a web browser and visit this page: Make sure your delegated calendars are checked.
  • Check out the troubleshooting steps above to see if they might help.
  • If your calendars are managed by an IT department, consult with them to determine which restrictions are in place.

Managed calendars are missing

If your device is managed within a corporate environment, and some calendar data is missing, it’s possible this is due to mobile device management (MDM) profiles. Please speak to your IT department so they add Things as a managed app to the MDM profile. This will grant Things access to managed calendars.

Changes to events don’t appear immediately

Normally, when you make a change to an event in Apple Calendar on the same device where you’re using Things, this change should be reflected in Things very quickly.

If you use 3rd-party apps like Google Calendar, Outlook, Exchange, etc., and possibly make changes on a different device, these changes might not appear in Things right away – even Apple’s own calendar app doesn’t get the information immediately. Instead, the changes are pushed to the origin app’s own servers, then to Apple, then to Apple Calendar, and only then will Things get notified that there’s new content.

Therefore, if you are using 3rd-party apps or services to manage your calendar events, certain delays are to be expected.

Strange events appear in Things

If you’re seeing strange events appear in the calendar section in Things, which are not present in your calendars, it is due to an Apple Siri feature.

Siri can look through your apps, like iMessage and Mail, and create events for you. For example if Siri reads in an email or message that you were talking about having dinner with someone at a certain time, it can create such an event automatically. This happens mostly on macOS.

This it not something that Things is doing as Things can’t create calendar entries – they are provided to Things exclusively by macOS or iOS.

Please consult Apple’s own support pages on how to disable this feature. As this is happening outside of Things, we have no way of addressing this ourselves.

Problems with permissions to access Calendar


After clicking an event in the calendar section, you see the following prompt:

Things needs permission to open the Calendar app. Grant permission in System Preferences, then restart Things and try again.

  1. Go to System PreferencesSecurity & Privacy.
  2. Click on the Privacy tab.
  3. Click Calendars on the left and check if Things is checked in the list on the right.
  4. If it is not checked, check the box, then reboot your Mac to see if that helps.
  5. Scroll down to Automation in the left list if Things is already enabled, or checking this option has not helped.
  6. Make sure that Things is present in this list, and that all checkboxes are ticked.
  7. You might get prompted to enter your Mac user account password as you're editing security preferences that need authentication.
iPad & iPhone

After trying to enable calendar integration in Things’ Settings, you are taken to SettingsPrivacyCalendars and Things is not showing up and you can’t enable it.

This happens rarely, but if you don’t see Things there, here’s something to check:

  1. On your iOS device, go to Settings.
  2. Tap Screen TimeContent & Privacy Restrictions.

If this feature is enabled, make sure that in the Calendars section Things isn’t being blocked.

Open 3rd-party calendar app after clicking event


At this time we can’t influence which app is loaded when you click an event – it’s something that is controlled by the Operating System, not us. We might be able to work around that in the future, but we can’t give you an ETA for such a feature. For now, macOS will always open Apple Calendar for you.

iPad & iPhone

At this time, it’s not possible to tap a calendar event in Things and be taken to Apple Calendar. This is due to the events being displayed in a small section, and it's not possible to determine which specific event you tapped because these “tap targets” are simply too small. Maybe this will be possible in the future, but we can’t say if or when this will happen.

Dates in the Calendar Are Wrong

If you try to pick a start date or deadline, and notice that the days of the week don’t align with the correct date, you are using an unsupported calendar format. This issue is not related to Apple Calendar, though. Learn more here.
