A wonderful composition app! It allows for smooth music writing, and provides a plethora of easy to use tools! I use the free version, and it is a tad annoying with my restricted instruments (absolutely no pitched percussion...), but it is absolutely still usable. The only real issue I have is with the balancing of some instruments, though this app is mainly for composing so it's not so much an issue. A very notable one is the marching bass drum. I had to layer 4 of them on fortissimo to hear.

I love flat so much ever since my friend showed it to me, flat has genuinely been the best tool for writing my music online, flat makes writing music effortless, the system is easy to navigate, and very quick to use. although I do wish it had slightly less lag with playback that may just be an issue on my end. overall 10/10. I highly recommend flat to anyone wishing to write music.

I used to really love this app. It was a really smooth experience with very little bugs. It was easy to make music on, and overall a blast to mess around with. But over time, the quality of the app has gotten worse with every update. First off, I can't use a Gmail account to log in normally without the Sign In With Google menu popping up automatically, which is a problem, because most of the time, it just crashes the app. The music editor is buggy. The menus are the only thing good here.

Hello Ricky Corder!Thank you for your feedback on the login issues and music editor bugs. You are right, when using a Gmail account you must use the "Login with Google" button to login, but it shouldn't crash the app, could you please reach out to our support team at hello@flat.io so we can investigate on your case and fix this crash issue.
