Which platform to use
We cannot officially recommend any platform for video calls, but here is a list of some popular services that have worked well for participants in the past:
Google Hangouts
Available for mobile devices (Apple/Android), desktop computers.
Works in the browser on desktops, no app needed.
If you both have Google or Gmail accounts already, then Hangouts might be the right choice. Simply head over to the Hangouts website
on your laptop or download the Hangouts app on your smartphone. Log in
with your Google account and add the other person as a contact using
their email address to start a new conversation. You will see a a small
video camera icon within the chat interface, which starts the call when
clicked. Google also has a help page with instructions.
Zoom
Available for mobile devices (Apple/Android), desktop computers (Win/Mac).
Needs the Zoom app installed.
Zoom is the most popular video call service on the internet. The platform offers a wide range of functions and a stable connection. To use Zoom, you must register and install the Zoom software the instructions from the provider can help you get set up. In recent months, there has been repeated criticism of the platform's data protection. Zoom has responded by repeatedly improving the software. You can learn more in this analysis from ZEIT ONLINE.
Jitsi
Available on mobile devices (Apple/Android), desktop computers.
Works in the browser on desktops, no app needed.
Jitsi is an open-source alternative to the services of commercial providers. At https://meet.jit.si/ you can start a meeting and send the link to your conversation partners. Registration is not necessary. Under certain circumstances, Jitsi may have problems with the stability and quality of your video call.
appear.in
Available on mobile devices (Apple/Android), desktop computers.
Works in the browser on desktops, no app needed.
On appear.in only one person needs to sign up for an account. They
can then create a room and share the room address with their discussion
partner. If you want to create a room for your discussion, go to the appear.in website,
create an account (you can use an existing Google account), then create
a room and copy the address. When communicating with your discussion
partner via email, you can simply share your room address and agree to
meet there at a specific point in time. When that time comes, open the
address in your browser and you will be able to see the other person.
You can also enter rooms from your mobile device via the appear.in app. Appear.in also has a good guide on how to get started.
Apple FaceTime
Available only on Apple devices, mobile and desktop.
The FaceTime app comes with the system.
If you both use Apple devices (e.g. iPhones or Macbooks), then you
don’t need to install any extra software – FaceTime is already installed
on your system. Simply add the other person to your contacts, either
via their phone number or iCloud email address. You will then see
buttons for calling them on FaceTime in your address book. Apple has more information on their website.
Skype
Available for mobile devices (Apple/Android), desktop computers (Win/Mac).
Needs the Skype app installed.
Skype has a suite of desktop and mobile apps for all platforms, which
are all compatible with each other. Share your Skype account name with
your discussion partner and/or search for them within the Skype app’s
contacts. Add them to your contacts and start a chat. Within the chat
interface, you will see a camera icon. Click it to start a video call at
the time you agreed upon. Skype also has a help section on their website with further information.
WhatsApp
Available only on mobile devices (Apple/Android).
Needs the WhatsApp app installed.
Video calls on WhatsApp are only available in their mobile apps, so
you need to have your discussion on your smartphone if you choose
WhatsApp. Exchange your phone numbers and add your discussion partner as
a contact, then tap the little camera icon at the top right to start
the call. You can watch a short tutorial on YouTube.
