I have tried many Qiblah apps and none of them worked for me. There is another kind of Qiblah app, and that one is different than the usual ones. I highly recommend it: https://play.google.com/store/apps/details?id=com.geospatialtechnology.visualqiblah
Don't use compass apps. They usually don't work well.
The best app is Visual Qiblah by Samer Joudi. Both internet (e.g. WiFi) and GPS is needed for it to work.
