Houseparty is an app to make group videoconference calls with all your friends. With just a tap you can start a call to any of your contacts, but the cool thing is you can add lots more people easily and turn what was a normal video call into a proper group call.
Before you start using Houseparty you'll need a user account. To get one, just provide an email address and pick a username. Also, once you've finished the process you can automatically add all your contacts from your smartphone (although you don't have to).
Do keep in mind that to use Houseparty the people you're calling also have to have the app installed. Both the download and the registration process, as well as the calls themselves, are completely free.
Houseparty is a fun and direct mode of communication thanks to which you can communicate with lots of faraway friends.
