This app is an indispensable part of every practice session. The portable, easy access to 1000+ jazz standards alone is worth the price. But these guys also included a little fake band to back you while you practice the songs. 🤘 You can edit the band by choosing instruments, turning them off and on, and mixing their volumes. You clean easily change the tempo of each song, the key of each song, and the basic groove of each song. Night mode is perfect. Highly recommended.

This is app really helps in reducing the amount of paper music I need to take on a gig sometimes. BUT, take the time to plan a set and make sure the changes to the tunes are correct. lt has its limitations of course, not being able to mark rhythmic accents being one of them. But I find it extremely useful in displaying charts on my 12" tablet when the bass player and I have to read the same chords in an unfamiliar key for a singer. Manage expectations, learn the tool, and it will be v helpful. Edited

Took a while for me to fully appreciate this app, but this a great tool for a student of jazz. You can get an accurate chart of any jazz standard, transpose to any key, export a pdf of your chart--you get a back track, change the tempo. I think I have access to 1200 songs. Try that with a fake book! And good customer service as well. Must have for any jazz student.

GREAT to have access to such a huge library of user-created arrangements! Searching for songs can be hit-or-miss, and I find it too complex to input my own songs, but I don't read music and don't know how to chart, so maybe that's normal. One-time price reasonable. There's no way to input melody, but that's due to copyright infringement laws. WONDERFUL for new musicians learning uke, guitar or piano because you can view chord diagrams and see where your fingers go!

I use this app all the time, I bought both Android & iOS versions. It's great for practice & education (I create charts for my students so they're playing along with a rhythm section as opposed to a clicking metronome); I use it to add drums to home recordings; I use it to provide structure to jams; I use it to help transcribe songs I'm learning. I recommend it to anybody that's interested in an aid to practice, education, and just plain playing for fun. Edited
