LOVE this app I am a Cantor and guitar player at church, and did masses solo for years. Now I have a young I piano player and a few singers to join in. I use some contemporary Christian songs and I only have the words and the guitar chords. I use this app to transpose to piano when I have a song that requires a capo. It works superbly!! I’ve used this app for about 7 years+. I don’t like or use any other app.
