Tab Toolkit from Agile is one of the most feature-rich guitar utilities on the App Store. It’s an app that helps you learn new songs and practice techniques, chords and other guitar exercises. With the most beautiful guitar tab interface available on the App Store, if you play guitar and like tab, you need to take a look at this app. It formats tabs beautifully, plays all instrument parts so you can hear what you’re trying to play, and makes it easy to find new tabs. Seriously, what else could you ask for?

Covering songs is one of the more fun things you can do with your guitar outside of writing your own material. It’s fun to play songs people can already recognize, and possibly even more fun to modify them, or cover them in a different style. Capo 2 is very likely the best tool available for helping you do just that. It’s a tool that analyzes music to help you create guitar tablature, but it is a bit pricey.

You have to love a company who’s name is SuperMegaUltraGroovy. And it’ll be even easier to love them after seeing that their newly announced app, Capo 2, looks to do a pretty amazing job of identifying notes and chords in songs just by analyzing an MP3. They call it “a highly detailed spectrogram visualization,” but what that means to you is that you may no longer have to have years of practice and a great ear to figure out how to play a song with your guitar.

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.
