Songineer is actually a lot of fun to play around on. The result isn’t a high score or an adrenaline rush, it’s a piece of music you have composed and can listen to, save and share with a friend. I like music, so this is inherently cool as a plaything and totally cool in that it’s really a tool in toy’s clothing. Even if all you want to do is bang around with something that has enough settings and controls to make the boys at NASA go “oooooh, that looks neat!” there are hours of entertainment to be had with this app.

Guitarist is an app developed by Moo Cow Music that attempts to be your on-the-go guitar. It’s not going to replace your real guitar, but it might help you seize the moment when creativity strikes.

Since the iPhone has multitouch, using it as a guitar simulator makes sense. There is one striking negative about this app, and I want to get it out right at the start. Since you’re only working with a piece of glass, there is no tactile feedback. It should be noted that this is not a problem with the app, but a limitation of the device itself. If you can get over this one point, then you’ll love this app.
