Manton Reece’s new iPhone app, Sunlit, is out today and available for free on the App Store (with an In-App Purchase to unlock the full version). I think it’s a nice idea: Sunlit is Manton’s take on iPhoto web journals, but built for App.net file storage and sharing.

You choose some photos that “tell a story” – could be a trip, a family gathering, anything you want to remember – and the app pulls in their metadata for date and location. You can add text comments to jot down memories, import photos from Dropbox if you don’t keep them in the Camera Roll, and even add check-ins manually, from Foursquare, or from Steve Streza’s Ohai app. When you’re done, you end up with a story that has full-res photos, text, GPS and time metadata, check-ins, and possibility to invite other App.net users to collaborate (here’s my sample story).

I don’t think that I’ll use Sunlit regularly because I’m not sure I could get my parents (essentially, the only people I share personal photos with) to sign up and use App.net. But I think that Sunlit is a good idea that shows how the App.net API can be used for more than social updates (Broadcasts being another good example). Manton knows the importance of preserving digital memories and I’m looking forward to future updates to Sunlit (there’s no iPad version or video support for now). Sunlit is available on the App Store.
