Composing, transposing, arranging - it’s all here with iWriteMusic
Super easy with great functionality! Incredibly affordable. The developers are very responsive to requests for additional functionality. Great online tutorials to get started, and to discover deeper functions. Really truly, iWriteMusic is competitive with Sibelius and Finale in what you can do; it’s far more intuitive and accessible to the beginner; and it’s a fraction of the cost. Teachers, use this to help students hear their compositions and their harmonies. Orchestra/band leaders, enter the part, and easily transpose for instruments. I’ve been using this for years and I love it!

Practical clever cheap
I’ve used iWriteMusic app for about 7 years. I own a very expensive comprehensive program, Sibelius but rarely use it now because iWriteMusic is so easy, intuitive if you use it for an hour or two at the beginning it gets really so straightforward. One weakness is it doesn’t import files. The export function is great and I’ve used it for not only myself but also my semi-professional choir colleagues to learn difficult passages we stumble over. I also use it to compose in 4 parts, for my granddaughters nursery rhymes and have even used it to compose orchestral suites. I instrumental sounds section could do with upgrading but for an app this price, it’s amazing.
