When it comes to photo-centric social networks, some may shy away from the Facebook-owned Instagram if they prefer a quieter environment for sharing images. But what if you could dial out the noise and actually tame the Instagram experience instead? That’s the premise behind Gramatica for Instagram, a $0.99 app that serves up a handful of features currently overlooked by the photo sharing service. Want to quickly switch between multiple accounts? Prefer to filter out certain tags, photos, or even entire users? Gramatica has your back.

With an iPhone in my pocket, a trip to the grocery store isn't nearly as unpleasant as it used to be. Thanks to a slew of advanced features that have made my lists smarter and more powerful, I've learned how to save money at checkout and dramatically cut down on the return trips I used to make after forgetting to pick something up. Shopster wants to make the experience even easier. By eschewing common features like iCloud syncing, virtual aisles, and barcode scanning, Shopster focuses on what's most important: What you need to buy and where you need to buy it.

Yoga apps dominate the health and fitness scene in the App Store, but gaming giant Electronic Arts – best known for action-packed titles like Battlefield and Madden NFL – is something of an unexpected contender in this space.

Like Captain Ahab from Moby Dick, we relentlessly seek our own white whale: A way to curate digital photos on the Mac, sync them to the cloud, and make the whole collection accessible from iOS. All of the services we’ve caught in our net thus far have been tossed overboard, but another has now surfaced on the horizon. Picturelife may not completely live up to “white whale” status, but it’s definitely worth harpooning. With the right subscription plan, we can upload even a massive library to the cloud (with a few caveats), complete with automatic organization and duplicate detection while backing up images stored across multiple social networks.
