Great Music Creating software

This is an amazing app. It’s free for one thing, which is amazing unlike other software/apps and please do not change that. They have a cheap premium plan that gives you some extra but definitely not necessary features and helps support the devs. I use the app on the go and the website at home and both are amazing. You have access to all the features no pay walls, it’s laid out logically and easy to find things. If you don’t understand something there is a great help page with simple explanations. I only have two problems. One: The violin synthesizer isn’t the greatest. And 2: The app gets weird when you have >8 instruments or get too long of a composition. Also some features from the website need to move to the app (harmonics, line customization, written - in things like corde, and LH pizz for strings). Other then that, this is the best music notation app on the App Store.

Thanks a lot for your review! Regarding these features that are only available in our website right now, they will be added in an upcoming release in our iOS app as well.

Good for pop songs, not for symphonies

Let me preface this by saying that this is my favorite music software. It is easy to use and if you know your way around, it will give you what you want.
That said, if you write a piece that is too big(more than about 3 minutes or two instruments), you start experiencing problems.
Let’s talk about my 200 measure Acapella medley. For starters, it takes an average of three tries and 90 seconds to get all of my instruments on screen. It regularly refuses to scroll and leaps back to the beginning of the piece for no reason whatsoever. Playback is consistently scratchy past measure 180 and it is getting hard to put in new notes because the app apparently does not want to click where I want it to click. Copying and pasting is also becoming an issue, as it sometimes refuses to highlight and sometimes inserts measures smack in the middle of the phrase I was trying to paste.
Long story short, this is a great website and I recommend this to anyone writing music. But emphasis on WEBSITE. The online website only has one of the aforementioned problems (jumping to the beginning).
Please make this app more phone-friendly. Hugs and kisses.

I absolutely like be this program! I have been using it for the past 4 years and it’s amazing that with a free account you can make 15 songs! Don’t get me wrong, I have had to delete a few to make space, but I think that’s a good amount! I would buy the full version online but I don’t have money of my own XD. I totally recommend this program! It’s so easy to use and has most everything you would need to write music! The only flaws I have ever seen are just the audio. Usually use pano for everything so it’s not a big issue for me, but some of the instruments sound very unreal. Recently. Have been making percussion pieces and the instruments don’t have the same feel. What I think would be awesome is if there was a way to put in your own sounds from garage band or something and Ben upload your own recorded sounds! Other than the sound quality, this has been the only program I have ever used! As a matter of fact, even though the sounds could be improved, they are at least better than every other pr gram for have used!
