As of v7.0.0, AppWererabbit is fully free.
If you like any of my apps, and wish to make a donation, just download this app, and keep it install for at least one hour, so as not to trigger an auto refund. Thanks.

Important: On Android 8.0 (API level 26) or above, the app may not works due to "Background execution limits" introduced in Oreo to improve battery life.
To overcome this, follow below steps:
(1) goto the "App info" screen
(2) then select "Battery > Battery optimization"
(3) set filter "All apps"
(4) locate and select AppWererabbit (PRO) Key
(5) select "Don't optimize", then "DONE"
(6) restart app to confirm is working

This is not a standalone app, but a license key for AppWererabbit (v6.6.0 or below).

Install AppWererabbit from https://play.google.com/store/apps/details?id=com.aw.AppWererabbit
