The 800-pound gorilla in web-based communications, Skype recently made group video calls free for everyone (with up to 10 participants allowed). This well-worn app has a huge installed base, which means you’ll likely have little trouble getting people to join a video chat on the platform. It helps that it’s dead-simple to use, though business features are limited to a rudimentary screen-sharing feature.
The ability to call regular telephones just about anywhere in the world for low per-minute rates is perhaps its most appreciated bonus feature.
Platforms: Windows, Mac, Linux, iOS, Android, Windows Phone, Xbox One, and more
