We have had several iPhone users reporting crashes on the Calm app after updating to version 3.11 of the app. This should be fixed by updating the app to version 3.11.2. We have confirmed that deleting and reinstalling the app will resolve the issue and prevent any more crashes if you do not see an update on your device.
Please note, as long as you are logged in to a Calm account, all of your stats and profile information will be saved when you delete the app. Simply log back in to your Calm account when reinstalling to access your session history and stats.
If you are experiencing crashes in the Calm app on an iOS device, please try deleting and reinstalling, and let us know if you're still experiencing the issue.
