Synthesia is awful and inefficient for learning piano. If you REALLY want to learn piano, try Piano Tiles 2.
According to the Google Play app store (not including all the iPhone users), over 900 million players use it, and there are 7.6 million reviews with an average of 4.5/5 stars. It's definitely the right way to learn piano.
If you are talking about this app then Uninstall it. It's from Chinese company "Cheetah mobile". Company that made Quickpic a zombie app.

Just take a look at this basic chart. It's about how these Chinese companies are related. (I noted important points from Wikipedia & other articles. It might not be 100% accurate. But It will give you some basic idea.)
My must have games are: Piano Tiles 2, Skiing Yeti Mountain, and Schrodinger's miniature garden.
