That’s probably the best thing about Skype – the fact that so many people already have it.
Since nearly everyone has Google these days, it shouldn’t be difficult to find another person with Hangouts.
The app does a great job with quick back-and-forth conversations, without any awkward silences because you can respond only when you have something to say.
You can also use the app like video voicemail, leaving messages for someone to watch when they can.
What's great: Of all the apps on this list, Imo is the easiest to use for video chatting.
What's not: There's no way to delete or hide contacts, so you'll see everyone in your address book who uses Imo, whether you want to or not.
More personal than a phone call, but just as easy, video calling is often free and the feature is popping up in more apps, including Whats App earlier this year.
You can also have group chats in Glide, where you send a video to more than one person, and everyone else can respond.
What's great: You don't need to carve out time for a video chat because you can send and reply to messages at your convenience.
Skype is one of the oldest, and probably the most well-known, video chat apps out there.
Skype allows its 299 million users to video chat, voice chat, and instant messaging each other.
