The Week in iOS Apps: Boomerang is Instagram’s latest offering

This week’s roundup includes Boomerang, a new way to make videos fun, from the folks at Instagram.

Boomerang is the latest offering from the folks at Instagram—it lets you take a few seconds of video that you can then loop back-and-forth, turning a simple action into a cha-cha dance. The resulting creations can, of course, be shared on Facebook or Instagram.

Crumbles turns your texts into videos: Just type in your message, and a mashup of movie clips will appear that deliver the exact message. If you include a word not in the app’s video library, no fear: Just make a video of yourself using the word, and include it in the final edit.

Earbits Music Discovery Radio offers 400 commercial-free radio stations—akin, developers say, to the mood and activity playlists at Songza and 8Tracks. You can even receive targeted recommendations based on the music in your phone—assuming, of course, you even bother to store music on your phone anymore in this streaming era.

I Am A Witness Keyboard offers more than 20 emojis, stickers, and GIFs that allow you to take a stand against bullying. “81 percent of bullying stops when someone steps in,” the makers say. “So use our keyboard to help end the bullying.” For use in group texts and social media, especially.

MacID “intelligently notifies you when one of your connected Macs is woken up, which you can authorise and unlock directly from your iOS lock screen using either your fingerprint or passcode.” That’s the old news. The new news? Now you can unlock your Mac using your Apple Watch. MacID requires a Mac with Bluetooth LE running OS X Yosemite or later, and an iOS device with Bluetooth LE running iOS 8 or later.

Miner lets you shop and get great deals from Forever 21, H&M, Banana Republic, Nasty Gal, Bloomingdales, 7 For All Mankind, Free People, Saks, Alice and Olivia, Tory Burch, and J Brand, among other stores. It is, the makers say, like having more than 20 clothing apps all in one.

It’s easy enough in iOS to share interesting information and quotes to Facebook, Twitter and other social networks. Quotle lets you do the same using actual paper books, newspapers, and magazines. (Some of us still use them.) Just snap a pic, create a text card that includes info about the author and the book, then share to your heart’s content. This week’s update makes it easier to search the Goodreads’ database to add the book and author information to your quote.

Vizable is an iPad app that takes data stored in CSV and Excel files and turns it into interactive graphics, letting you analyze trends and share information with partners and colleagues.
