DJFuturo Review:

One of Flat’s biggest strengths is how quickly you can start using it without installing anything, perfect for capturing ideas fast. It’s also intuitive and easy to use, which isn’t always the case with sheet music editors. That said, it doesn’t include as many advanced features as some alternatives, especially in the free version.
It’s also highly recommended for students.
