Best New Apps: IFTTT

Since it launched in 2010, IFTTT (if this, then that”) has been building a Lego set made out of web companies. The free service, which until now has existed only on the web, automates tasks using public APIs from companies including Facebook, Dropbox, Evernote, and Foursquare. I use IFTTT to save all my Instagram photos to Dropbox, and to note every time I check in at the gym, among other things. Now a new iOS app is making it easy to browse and enable the most popular “recipes” on the service — while also introducing recipes exclusive to the device that’s always at your side.
