Love it!

I’m using a very old phone and was so afraid I wouldn’t be able to access pianoforall ebooks but this app has been perfect 🥰 Thank you so much for keeping it free and for such a seamless experience ❤️

Many bugs

I downloaded this app because I purchase an e book to learn the piano. I cannot make an account, only login(but can’t login without making an account first) which means on the phone none of the files or books I add are saved. On my computer it is the exact same issue but my books are saved under the “recently viewed” section. It is unoptimized for iPhones with the island dynamic. I have no choice but to use this app sadly. Definitely needs more optimization

Pretty good ebook reader

I like this app a lot the only thing I can say neg is sometimes it glitches when loading an ebook, not all the times but once it loads the book it works just fine.
