Sometimes you want to connect with people who use the same apps and devices you do, but are you supposed to hunt them down on forums or shout in vain on social media? Heck no, you can just use AppChat. This app is so simple and useful I’m surprised no one thought of it before. Basically, AppChat creates a chatroom for all the apps on your phone or tablet. You can log in, talk to other users, and even share files. In addition to the app listings, you’ll also see device and manufacturer chatrooms specific to your device. It’s a great way to research bugs, ask for tips, and find new apps. Not bad for a completely free app.
