Snapguide, a free iOS app with a sister site, is like a cross between Instructables and Pinterest: a well-organized, easy to browse app with a clean design that allows you to effortlessly put together a how-to guide on any subject of your choosing with photos and video taken with your iPhone.
Your guide can then be published and viewed on the web, tablets or phones. In fact, Snapguide is optimized for viewing on smaller screens; the app makes it easy to browse guides, jump to specific steps, and share guides, making it ideal for having in hand while attempting to follow the instructions. It's also exceptionally easy to create the guides, which can be edited, rearranged or deleted as necessary before being published.
Guides range in category from automotive to arts & crafts to cooking to photography, fitness, technology, and pets, and can be easily shared via email or a variety of social media sites including Facebook, Pinterest and Twitter. The guides will show you what supplies you will need as well as the number of steps, and can also be viewed on the Snapguide website. Users can like and comment on guides, as well as send text and audio messages among each other (audio messages can also be added to guides themselves — Nuance technology is used to transcribe it).
Because Snapguide has only been live for a few short weeks, there are not as many guides as you might expect to see yet; however, the Snapguide community is sure to grow, as the service nicely bridges the gap between YouTube and eHow and provides an a way to easily capture steps in real-time. Although it's only available as an iOS app, the company is working on expanding to Android and other versions.
