There are a lot of Android users out there, and many of them probably use the same apps you do. AppChat is a clever app that lets you talk to them in a series of live chat rooms. This app was just released as an alpha on XDA, but it has tons of potential.
Google's long awaited carrier play was announced recently as Project Fi, an MVNO running on Sprint and T-Mobile that will begin as a Nexus 6 exclusive. The official Project Fi app is now live in the Play Store—not that it will do you a lot of good without an invite, which no one seems to have yet.
In their infinite wisdom, most US carriers opted to remove the Galaxy S6 settings to change the backlight timeout for the capacitive back and overview buttons (AT&T didn't for some reason). This may seem like a minor point, but it's actually rather annoying. Now there's an app that can fix that, and it's free.
After popping up in a leak several weeks back, Facebook's Android dialer app has been released in the Play Store. Rather than going with the generic and confusing "Phone," the app is called Hello. You can place calls, see who's calling, and block incoming callers.

Do you have a bunch of stuff that you don't need? You could try to sell it, but it might not be worth the piddly sum you'd get. Yerdle aims to help you get something out of such items by letting you give them away. In return, you can get other things from Yerdle users for free (sort of).

Once upon a time, Kodi was known as XBMC, and it was developed for hacked Xboxes. This open source media hub went on to run on PCs and mobile devices, but it hasn't been deployed in the Play Store until now. There are some not-so-secret Google+ communities for beta and alpha versions of Kodi, and you can join them right now.
Office Lens is an app that lets you capture notes, business cards, reciepts, and any other scrap of paper as a digital file. Microsoft released a version of Office Lens for Windows Phone last year, and now it's coming to Android as a beta. It's free, but you need to do the usual beta program song and dance.
