App stores are crowded places these days, and because storage space on your phone is often at a premium, you’ll want to find and fill it with not only the best, but also the most helpful apps out there. Because they come and go quicker than the latest fashion trends, and digging through Google Play, the iTunes App Store, or any of the others is such a mission; a little nudge in the right direction is often very welcome. Here are the apps we think you need to check out this week.

With the wealth of apps and tools dedicated to connecting us with others, meeting new people has never been easier. We’re still precious about our personal information though, and it’s wise to not immediately add people to Facebook, or hand out your phone number to others without giving it a little time first. For the middle ground between chatting up potential friends without surrendering account names to strangers, try Knock Knock.

Created by the app developers behind Humin, a contacts manager app, KnockKnock is the solution to the above problem. Knock twice on your device and you’ll see other people in your area who have also knocked because they’re looking to connect. Deal out your information as you wish as you get to know new people in your vicinity by chatting them up in the app. You never know who might answer when you knock.

iTunes, Google Play
