Christian Hymn Book is a free English hymn lyrics application developed for Christians, especially for those who believe in One Living God. The app offers over 300 songs that you can easily search for and view lyrics. You can also play MIDI music of some songs and share the MIDI audio with your friends. The app has a black theme layout with white text for easy reading and battery saving, and it also allows you to switch between dark and light themes. Additionally, you can keep the screen awake while reading lyrics and hide or show song numbers.

The app has basic features such as the ability to zoom in and out of the text with pinch zoom or using buttons, add lyrics to your favorites list, and share lyrics via email or social media apps. Moreover, the app is used offline, so no data connection is needed to run the app, and you can install/move the app to an SD card.
