Thank you for sharing your feedback. We regret that our Android app did not meet your expectations. Please note that performance can vary significantly based on a device’s specifications and screen size. Although the Samsung Galaxy S10 (released in 2019) remains a capable smartphone, more complex sheet music editing—beyond quick on-the-go adjustments—may be less convenient and potentially less performant on smaller screens. Devices with larger displays, such as tablets or laptops, often provide a smoother and more intuitive editing experience.
We noted your reference to MuseScore; however, on Android, it only offers score viewing and does not allow editing or creating sheet music, making it fundamentally different from our app. If you had also tried Flat on a desktop, you would have had a more robust experience akin to MuseScore’s desktop version.
We are pleased that hundreds of thousands of users across various platforms have a positive experience with our app, but we recognize that individual outcomes can differ. If you ever decide to give our app another try—perhaps on a laptop—our support team would be more than happy to help you optimize your setup and enhance performance.
Thank you once again for your review and for helping us continue to refine our product.
