Grid: Created by Josh Leong, Grid allows you to put any type of multimedia into tiles of a grid that are whatever size you want. You can make grids that mix photos, text, Google Maps data, symbols, whatever. And they're sharable so you can collaborate with other users. If you've ever used a GoogleDoc to organize a group of people, this is the beautiful version of that. Grid is only for iOS right now, but at least it's free. All you visual thinkers get crackin'.

Snap Save: Snap Save is a new iOS app that lets you save all of your Snapchats for future fun. Being able to save Snapcats isn't new in and of itself—there are other ways to do that—but unlike other methods, this app prevents the sender from knowing you've saved it. (If you take a screenshot of the image, for example, Snapchat notifies the sender.) Just open Snap Save to view your Snapchats, and the app saves a version. That's it. You can pay $2.99 for an ad-free version that lets you save the Snapchats to your Camera Roll. [Free]

MixBit: The new app lets you record and upload up to 16 seconds of video, which you can edit in-app. But then comes the cool bit: you can string together up to 256 clips—both yours and video belonging to others—into an hour-long video. Cleverly, the video isn't all lumped together, but streamed seamlessly as separate chunks from the be MixBit servers. Your finished product can then be shared on Twitter, Facebook, or wherever. But while the content sits on the MixBit servers it's anonymous: each submission is unnamed, and there's no commenting system either. Which might be a good thing, depending on what you're filming.
