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.

A couple problems

This tool is really good for most things, but there are a couple problems with it I noticed pretty quickly. 1 - The free version of the alto sax sound is PAINFULLY out of tune. I tried arranging a marching band show, that includes sax features, and had to cut out the part just because of how horrible it sounds. I am not exaggerating at all, if it has a unison with any other part, it will completely ruin it. 2 - copy/pasting is weird. If I want a trumpet/trombone unison part, chances are they will not be playing the same octave. If I copy a part from the trumpet line and paste it to the trombone line, it would be a lot simpler if it just transposed an octave down to the trombone’s practical range instead of being 30 ledger lines above the staff. Either that, or allow moving more than one note at once, like if I select a measure and move it down, it would be simpler than having to select each note and pulling it down. These problems are definitely not deal-breakers, there is a lot of really good stuff with this app and these problems are kind of niche(I don’t think a lot of people use this for marching band and jazz band pieces). All in all, it’s a good app, it just has a few tiny problems that would make some people’s lives a little easier if they were fixed.
