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).
