Easiest way to do Face-to-Face video calls

Let us talk about quick Video Call apps, like the one you would use when you’ve got an idea and want to get instant feed back from team members, without extra back-and-forth. Or you want to check the progress, find out how the project is coming along. You need is a quick and easy way to make a video call, with no sweat! There're quite a few apps for that, these are the ones we turn to:

Appear.in (iOS, Android, Web)
https://appear.in/
appear
Recommended for small team chats using browser.

In your browser (works with Chrome, Firefox, and Opera), go to appear.in, and click Start. After share the link with your colleagues.

On the upside

There are lots of useful features like a chat, text and links sharing, stickers/masks to cover your face, and if you install a browser plugin an option to share your screen. For Slack Users you get an ability to start a new call right from Slack with the “/appear” command. It's press of the button kind of way to have a video conference.

On the downside

Only up to 8 people can participate in the call for FREE, and it doesn’t support Safari browser.

It’s Free for unlimited calls with up to 8 people. Premium edition for 12 users per call will set you back $12/month per room, screen sharing alongside video, and custom branding (currently in beta).

Slack (MacOS, Windows, Web)

Slack
Best for call making directly from the chat app.

On the upside

Slack added one-on-one voice calls in June 2016, six months later they added a video to those calls. If you are a Slack User, to call a colleague, just open direct message or a channel and click the phone icon. The app will start the call in a new window and add a notification to the chat. Calls feel “normal” a bit like a regular phone call with video added on.

On the downside

It’s limited to up to 15 people per single call, and video calls only available for desktop/laptop version. It’s not free, the Standard plan starts from $8/month for video calls, however, you will get unlimited chat archive and priority support along with it.

FaceTime (iOS, MacOS)

FaceTime
Best for Mac & iOS users one-to-one video calls.

On the upside

Must be one of the simplest way to make a video call. Its built into your iPhone and Macintosh. The main advantage is that you can make a quick video call over your data connection, it'll sound great, even over congested airport Wi-Fi.

On the downside

The drawback is that you will you'll need to use a different app for messages since the Face Time doesn’t support messaging.

Skype (MacOS, Windows, Linux, iOS, Android)

Skype
First Free online calls app most of us have used.

On the upside

It’s good for a one-on-one call and it now offers team calls with up to 25 team members for free, and with plugin previously installed will even let you join the call from the web.

On the downside

Unfortunately, it's not as reliable comparing to other apps. When we used it in Pacto we could never get it to reliably work for more than 2 people in the call. Even with just voice-only we had issues like lagged or dropped calls.
