Piano HD 4+

I can make up my own songs and it is enjoyable but there is this bug where if I tap a key it stays grey but it does not really matter Overall, the game is fantastic!😃

First, the app is amazing. You can learn how to play cool songs and even create your own. You can also make recordings and show your friends. But here's a bug, when you press a note it turns grey, which it is supposed to, but certain notes stay grey and you then have to press that note again to get rid of it. Apart from that, the game is alright. But it isn't 5 star without the bug. If you cannot already play the piano, don't bother downloading it.

It seemed to be a fine app, great sound and keyboard. But unfortunately the "record" function does not work. It records, but there is no sound. I sent the recording to my email, and that mail facility works fine, but the ".caf" file which was attached still doesn't play.
I tried to get support/feedback from the makers but their website is completely Chinese with no English translation.
So this is useless and it has cost me £2.29
