I am constantly looking to improve and update this app and welcome suggestions, requests, etc.

OpenSongApp is designed to compliment the Open Source application for Linux/Windows/Mac called OpenSong that allows churches to project song lyrics, Bible verses, etc. You can check them out (and support them) at: http://www.opensong.org

If you're looking for an alternative to the other expensive apps out there that doesn't see you as a customer, someone to make money from, or someone to bombard with ads, you've come to the right place.

OpenSongApp for Android started out free of charge, is currently free of charge and will stay free of charge for the lifetime of the app. All of my features are available. No additional in app purchases, unlocks, adverts, enhancements, etc. You get it all, all the time!
If you don't like it, no worries, move on, life is too short!
