I used to use a sound-recorder app (that will remain nameless) to record my song ideas on the go. It wasnt perfect, though. I wanted to be able to jot down lyrics and chords (sometimes the iPhone mic doesnt record an electric guitar and vocals with the utmost clarity and I couldnt make out what exactly the words were). When the app had a disastrous update that wiped the titles off all of the files, I decided I needed to do better. Songwriter really delivers. It really formats the data entry in a way that makes sense from a songwriting perspective (you can break each song down by section, can add lyrics AND chords, and record an audio file for each section). Mix in a handful of export options and you have a safe little corner of your phone to get creative in. (I wouldnt say no to an iOS7 update, but hey, were just splitting hairs at this point.)
