iOS: It's admittedly a little silly to need an app to remind you to grab your key or wallet before leaving the house, or your lunch bag before leaving work for the day, but we all forget those things from time to time, especially those of us coping with mental illness. Don't Leave It! helps you remember.
Web/Android/iOS: Human trafficking is a massive, global problem -- one that an app alone won't solve, but one that this app may be able to help with, just a little bit. TraffickCam asks you to snap pictures of your hotel room, creating a database that can be matched to rooms in photos with trafficking victims.
Google's new "Trusted Contacts" app and service makes sure your loved ones always know where you are or can find out where you are if there's an emergency. It's opt-in from both sides, only shares in real-time when you want it to and can put an end to "where are you, are you OK?" texts when someone's late home or to a meeting.
Android/iOS: Hound is fast -- really fast -- and while your phone probably already comes with its own virtual assistant, Hound integrates with services like Uber and Yelp. The team behind it hopes more will follow, for a truly cross-platform assistant that does the same work for you on any device.
