Tried several apps to digitise music for church - with no joy. This works fine on my old Samsung Note 10 - the customisation and autoscroll are great, and it responds well to the odd swipe mid playing if you get out of sync. Had dropbox problems until I deleted the free version - all OK now. There's a bit of a learning curve and the documentation is a bit on the light side - like how to copy and select text in the editor. I bought it so it must be OK.
