Ratings and Reviews

Gives Finale a run for its money

Almost as good as finale

This app is an amazing tool for any songwriter. With the ability to create an orchestral movement on the go, this app is a must have. I play the piano, and this app has helped me compose music while balancing my busy school schedule. The app has almost all the tools one might need. The program alerts you when you have made a mistake, it allows you to copy and paste entire sections, saving you a ton of work. It also plays back anything you write so that you can check yourself for errors. With numerous built in presets for timings, keys, and and octaves, this app is easy to use, and at it's low price, is a great deal. I have only had two problems with this app so far. First off, if a song is becoming lengthy, the app has a tendency to crash, causing me to save my work frequently, or risk losing what I've been working on. The only other problem is that the program seems to be missing a grace note feature which I'm sure they will add in a later update (hint).

Superb, but frustrating


I've had iwritemusic for years, and upgraded to the full version not too long ago. The app's mechanics and features are excellent thanks to a straightforward system and a wide array of options. Sadly, there are some issues that have been around since the app's debut. The most troublesome problem is the fact that the app crashes... A lot. The device I am using is a bit old, but is updated and more than capable of running the software, but crashes happen at an alarming rate and it has been this way for years. The other main issue is with the playback feature. Options are very limited in this regard. Dynamics are not represented. Instrument keys don't seem to carry into the audio playback. Other than these problems (crashes being the biggest issue), iWriteMusic is quite a good option for anyone trying to compose or arrange music on a mobile device.

Great application


Simply put, this is a great application for composing music on the go. I am by no means a professional composer, with that said, this application has everything I need to compose music. It also includes an option to export as MIDI, which very helpful for transferring songs to other applications.

Now on to some of the downsides to this application. One downside is that sometimes while trying to scroll across the screen, it reads my gesture as an attempt to place a note. I am using an iPhone, so I don't know if that issue is as relevant on an iPad. Another downside is that there is no "select note" mode, for easily deleting or moving multiple notes.

Overall this is a great application that I highly recommend!
