It needs MIDI support; until then, it's not the best for beginners. Edit (Response to 'The OP Team'): It's cool that you're adding MIDI and mic support, but, that's only for iOS... Those features (when they come out) will have no standing on my rating for the Android version; at most, it may cost this version to lose a star as it would become inferior.

I've been using this app for a while and it's by far my favorite one amongst the rest. I've downloaded others but always end up uninstalling them right away. This is the only one I keep and have on all my devices. Even their support team is great. I had a bug that caused me to not have any access to the songs in my book even though I have a subscription. Yoav Tenenbaum was incredible and fast to find and resolve the issue I had. Great songs and great service!

This app should be rated easily over 4.6. I believe that if the users that gave 1 star rating took a second to really read what the yearly subscription is, which is 7 days free period and then 5 euros per month (total of €60 for the whole year) this mess of a rating would never happen. The app in itself is the optimal tool to learn how to play piano, which by tweaking the settings can be custom tailored exactly to your current learning stage, and then readjusted as you progress instantly. You can learn left or right hand keys individually by muting the other hand keys or taking them off the screen altogether. Each song is divided into segments so you can set a goal and focus on learning your segment of choice and with the loop feature (AB) automatically the app will play only that specific segment on loop without having to manually set it back. The finger numbering, the speed setting, the metronome, pro/beginner version of the song, all of these features will no doubt help you get the maximum out of the time you spend playing. I am truly amazed by the level of well thought out feature structure of this app. Which I am certain took endless hours of work putting it together and readjusting to get it right. And you don't have to purchase anything from the get go. These folks are giving away free songs. I have downloaded 10 and 5 of those, I really like. Start with the free stuff and when your playing ability increases and you can learn at a good pace, buy a subscription to unlock the entire song library. Personally, that's what I will do. I apologise for the lengthy review, but I felt I owed it to the developers and to you guys to know how things really are. Hat's off to you people of the online pianist team. Brilliant job. 😀
