I have been able to keep my aquarium running for over 3 years because of this app. If you experience crashes its an easy fix. If you are using iCloud you wont loose any data. First thing to try is to delete the app then reinstall. If that does not work go to Settings App -> iCloud -> Storage and Backup -> Manage Storage -> aquaplanner and delete all files that are photo.data, photo.metadata, or start with numbers. Then relaunch the app
