In almost every case reported to us, the reason for the app crashing when launched is due to corruption during download or an error during installation. The easiest and quickest way to fix this problem is to:

- Log in to your account at the App Store (Apple) or the Play Store (Android).
- Re-download and reinstall the app (you own the app, there is no additional cost).
