Digg, Milk, and Revision3 founder Kevin Rose recently left Google Ventures to start a new mobile development house called North, and now we have some details on the firm’s first app, Tiiny, which will launch soon. The basic idea is that Tiiny lets you share thumbnail-sized photos and animated GIFs to a grid of pics on your friends’ phones, and they disappear 24 hours later. Rather than making you scroll through full-width photos like Instagram, Tiiny lets you get a constantly-updated look at what lots of your friends are up to in a single glance.

Rose told TechCrunch founder Michael Arrington that the app is currently going through the iOS App Store approval process and should launch very soon. Rose’s team said he’s not ready to talk more about the app just yet, but we’ll have more details on TechCrunch when it’s time.

I did get a quick look at the app yesterday, though, and it’s slick. As you can sort of make out from the photo below, the top of the screen features a 3-wide by 4-tall grid of photos and animated GIFS, with a button to capture and share more at the bottom. Seeing all the moving images on the same screen made the app feel vibrant and alive, which could make it addictive to check compared to more static apps like Instagram or even Vine, which only shows one video at a time. Rather than a replacement or direct competitor to other more public broadcast and direct messaging photo apps, Tiiny seems like it could fit in as a complement.

There’s also supposedly some more functionality but we’ll have to wait until it’s out for that.

North, which we profiled last month, has a peculiar strategy. Rather than languish on building one app, North is trying to use a small team of about 3 people to launch a new mobile app every three months. This scheme lets North quickly throw apps against the wall and see what’s sticky for users. With building social apps being likened to capturing “lightning in a bottle”, this diversified approach means North won’t spend a year building something no one wants. If Tiiny is a flop, the team will just move on to the next app.
