Crashes 4x upon startup – Boost Cleaner: Clean Storage + Review

This app crashes 4x upon startup. (Tap, goes to white screen, white screen for 5-10 seconds, and crashes). Maybe it needs to be updated for iOS 12.1.2. Last update was 8 months ago, before iOS 12 released. Glad it works for most of the users who reviewed it.
