Hum is songwriting for iPhone. Hum combines note-taking and audio recording into a single app for capturing and organizing all your songwriting ideas. We sell the app for $1.99 with the option for in-app upgrades. Our plan includes 2 phases. 1) Get every musician writing songs in Hum. 2) Get every fan listening to those works in progress in a show and tell for songwriters. Follow artists and listen to 12 seconds for free. $30/yr for full songs.
