Forgot Passcode on iPhone / iPad:

  • The easiest solution is to try and remember, maybe spend a while guessing possibly combinations.
  • The next easiest solution only works if you are certain that your data has been synced to Dropbox, iCloud, or Day One Sync. If that’s the case, you can delete the app from the device and re-install it. Then re-sync your data from the previous sync method.
