One piece of advice

This app is amazing, and is the best on the app store for music notation apps. Its amount of content, ease of access, and scope all outshadow its competitors. My only suggestion is an addition to your premium plan which I believe should have microtonal accidentals. This is because currently there is no real motive to get the plan, so an extra small incentive might help. Obviously these are not especially important to a normal person, but these would help certain composers and teach others a new way if writing music while providing a reason to actually get your plan. Of course, it might take a while to notate every instrument, so I advise only adding it for piano and strings, and maybe woodwinds and/or brass. These should encompass the plus and minus marks which are part of the Pythagorean tuning system, and also one-fourth and three-fourth flats and sharps. Thank you for your time.

Good for most people

This app is great for if you just want to write something out quick. Obviously the phone isn't going to be most ideal method of composing music, but I feel like there are a few things here and there that could use some tweaking. Particularly with the guitar interface. I know I'm probably a minority when it comes to this, but I would like to use this so I can transcribe songs accurately, most of them being rock/metal songs, which are sometimes in different guitar/bass tunings like D standard, Eb standard or drop C, and while you can write in lower notes than what's accessible with standard E, it won't show up on the tablature, which, if you're someone who uses tablature primarily, can be a little inconvenient. So lower tunings for guitars/basses I think would be a welcome addition. Also, many of the guitar techniques that you can write out on the app won't happen during playback. For example, palm muting doesn't change the guitar sound, it just says that the notes are palm muted, bends and pre bends sometimes won't even appear in the music even after repeated attempts to add them in, and even when they do get added in, the notes will not bend during playback. Letting notes ring also doesn't do anything during playback, it just says to let the notes ring. Otherwise I'd say this is going to be fine for everyone else, which is why I gave it a 4 star rating even if I personally had some problems with it.

Very hard to use !

This is the third time I’ve tried to leave a review and they keep disappearing before I get a chance to push send ! there is no tutorial to teach you how to use this app. there are lots of help cards to teach you how to use advanced functions of the app but nothing how to teach you how to use it in a basic way. first I couldn’t figure out how to put two notes in the same place I found that by mistake. but there is no tutorial on how to do it. there is no help in the community because there seems to be no way to talk to anyone in the community just a way to post music. Every time I get to the end of a bar that I’ve written it adds a new bar with a couple of symbols I don’t recognize and a bunch of rest that I don’t want in the music. I cannot figure out how to get rid of them when you try to delete them it simply deletes everything you wrote and leaves the things that it added without your permission. as a result I cannot make this app write out a simple drumming exercise so that I can repeat it. I also could not find a way to get it to repeat the notation as most songs repeat the same pattern many times. Attention developers if you want good reviews for your apps you need to show people how to use them !

Developer Response ,

Thanks for your feedback. We do have a quick getting started steps, and then some short help videos regarding most of the features available. We cannot obviously show everything when you start using the app, as not all the features apply to everyone. The feature you are looking for is "Voices", and there is a help page and video in-app about using this one.
Regarding the "unwanted measures", Flat always inserts new measures when you write your music, it saves time and avoids manually adding those. When you are done with the score, just remove the last measure from the measure toolbar to remove a potential last empty measure. The measures by default contain quarter rests (or similar depending on the key signature and nothing else). If you need any help, please contact our support at ios@flat.io.
