Screen-sharing tools are a good way to make presentations to colleagues and clients, especially with so many people working remotely right now. 

There are dedicated screen-sharing apps which are really designed for troubleshooting, but there are also video-calling apps such as Zoom that offer the option to share your screen.

The benefits of screen-sharing are many, and almost all of them can be used for free - with a few limitations here and there.

Facebook recently launched screen sharing in its Messenger app, available on iOS and Android. It's an addition to video calls and messenger rooms but requires each participant to have an account and - more importantly - be 'friends' with each other. So this is a great option for families and friends, but less suited to business use.

These are the best free screen-sharing apps for small businesses:

Zoom

Zoom

Zoom offers a free video-conferencing app with a wide range of features that can be used over an unlimited number of meetings. It is available for anyone to access, as longs as the link and meeting password is shared with all attendees.

The basic plan, which is the free option, limits the time of meetings to 40 minutes but from £11.99 a month you can spend however long you like on meetings.

Its screen-sharing feature allows users to either share their entire desktop or phone screen, a specific app, Zoom’s whiteboard, or a portion of the screen.

The easy to use app also allows users to record the calls, which means that hosts can share the meeting with team members that were unable to join.

Skype

Skype

Skype is another free video-conferencing tool, which offers screen-sharing with no need to sign-up or download the app.

Owned by Microsoft, the tool can be used via the web and includes call recording and live subtitles as part of its audio and video calling feature.

The app provides its screen-sharing feature and it is also available online, which enables users to share their full screen, presentation and pictures.

Skype is free to use for video calls and sharing screens, although there are charges for calls to landline numbers, SMS texts and voicemail.

Google Meet

Google Meet

If you are a Google account holder or have a Gmail account then Google Meet is a great video-conferencing option that is also available for free.

The audio and video calling feature hosts up to 100 people. All you need to do is share a link, which you can easily add to the Google Calendar for all attendees.

Its screen-sharing feature gives you the choice of how you want to present your screen, such as the entire screen, specific tab, application or document. 

Google Meet also includes noise-canceling and real-time captioning features. The only thing to remember is that all meeting attendees also have to be Google account holders to access.

Webex Meetings

Cisco WebEx Meetings

Cisco Webex Meetings is a free video-conferencing solution, which allows you to host meetings of up to 100 participants. 

The video and audio calling also includes the option to share your screen, whilst also hosting a personal conference room for one-to-one and small group meetings.

It also includes the flexibility to host meetings without a time limit. There's a desktop app but the service is also accessible via a web browser. Users are not required to have an account but can host and access meeting using a provided link.

TeamViewer

TeamViewer

TeamViewer is a remote access tool that can be used for troubleshooting and remote access, but you can also use it to share your screen with other people.

You can share your entire desktop or only part of your screen. TeamViewer also has file sharing, chat and whiteboard features.

It is available on Windows and macOS, as well as Android and iOS for phones and tablets.
