1. It has 2 handy buttons, the left scrolls the keyboard over the whole of the piano's range and the right button zooms in and out of the keyboard making the keys fatter or thinner so the screen can show a bit more than an octave, or a bit more than two octaves.
2. Initially this looked ideal for helping me figure out my notes from choir music - correct pitch, simple to use, and the sliders to allow more of the keyboard to be displayed.
3. The UI is fine but several bits seem poorly thought out - for example zoomimg key width is a good idea, but it zooms from one end so doing so moves all the keys to one side of the screen.
4. However, using the righthand slider to reduce the size of the keys from the default size does make it easier to navigate.Works just great for me.
5. But every few seconds the keyboard shifts so that less and less of it is displayed on screen until after a minute or so the whole keyboard has disappeared from view, so you can't play it anymore.
6. Cool, I can play chords with my podgy fingers!!I tried many different apps but they all had keys slightly sharp - this one is at least bang-on pitch.
7. Also when two keys are pressed at the same time then letting go, it seems sound of the lower one is repeated on release.This piano app is the literally my favorite.
8. But some problems I am now finding: volume too low in lower octaves, but when I connect Bluetooth speaker a latency issue [between pressing a key and getting sound]; becomes apparent.
9. Easy to use, no boring tutorials (it's very intuitive, you can just figure out by yourself the functions), let's you play more than one key at the same time, it's free, it does what it promises.
10. It is somewhat difficult to move to different sections of the keyboard using the lefthand slider.
11. 8 bass notes you can play with 1 finger and 16 treble notes , with practice you can almost resemble the real thing.
