Apple released GarageBand for iPad back in March, coinciding with the launch of the iPad 2. GarageBand for iOS 1.1 [iTunes link] adds support for smaller devices as well as a few new features and tweaks.
If you already own GarageBand for iPad, you can download the iPhone or iPod touch version for free. The interface is now optimized to use the smaller screen of the iPhone or iPod touch, but the app is largely the same from a functionality standpoint.
This is a good thing. GarageBand for iOS is a tremendous accomplishment. Apple has managed to take many of the best parts of the GarageBand for Mac app and bring them to touch screen devices. Plus, using the headphone jack on your iPhone or iPad, you can plug in an electric guitar into a device and use the app as an amp.
You can mix up to eight tracks together and as we've seen in the past, the results are quite stunning.
In addition to iPhone and iPod touch support, GarageBand 1.1 also includes:
Support for 3/4 and 6/8 time signatures
Ability to set export settings at AAC or export uncompressed as AIFF files
Adjustable velocity settings for touch instruments
Custom chords for Smart Instruments
