Very playable, needs update – Futulele - Digital Ukulele with FX and chords Review

I have played the viola, acoustic guitar, electric guitar and ukulele (electric bass is next). This is very playable for when I am away from my instruments. A way to back up your chord sets, assign auto playing styles and speed per chord set would be nice. In latest version for iOS 9, automatic locks up.
