Ratings and reviews

My phone's whole system got painfully laggy for no apparent reason, but it was since I enabled this app. Uninstalled it a minute ago, and so far the problem has vanished. Not quite conclusive evidence, but it does seem likely that this app caused the lagging. and I don't see why a colour filter would need to use resources constantly. Nor, for that matter, why it would need permissions for full network access / view network connections / receive data from Internet... 🤔

The permission for this app stops frequently and it requires me to turn off the permission, then back on. This turns the filter off at inopportune times. Occasionally the permission will fix itself, thus turning the filter on randomly when I want it off. Using Android 12. No updates since 2023, is the app development dead? Otherwise, it works as needed.

App now broken - when watching ad to get 10 days free, there is no way to continue and claim the "reward" anymore; if I go back instead there is no reward claimed.
