The iPad is great for lots of things that usually require lugging a MacBook (or real books) around, and reading how-to guides is one of my favorites. But what if you want to create your own guides that others tablet owners can use? iOS app Snapguide has been making that possible using an iPhone for a while, but now it's available as a universal version with an iPad-tailored interface.
The app serves as a companion to Snapguide's website, letting users discovery guides created by others in addition to building their own. It allows favoriting, commenting and sharing via various social networks and sports a browsing interface that looks quite similar to Pinterest (which is itself a how-to guide aggregation site of sorts).
You can download Snapguide from the App Store for free. Let us know in the comments if you end up making some handy guides with it!
