Does anyone else here think songsterr sucks?

I mean, i was recommended the app and it was decent for a few days. But i cant get past them blocking the tabs 10 seconds in to get you to pay, on some songs the line doesnt match what notes are being played, and some songs it just straight up skips entire bars because it didnt feel like it. And if you pause the song, when i play again it plays the song then 3 seconds later the line suddenly snaps back to position after not moving. Please tell me some other sheet apps before i just use youtube🙏
