Join Me is a great application which allows you to share your computer screen with someone remotely. The free version allows you to safely show someone else, in fact up to 250 other people, your screen by downloading a code which you then give to the people you want to share with. You don’t even need to sign up or register. This is great if you want to work collaboratively with people and if you upgrade to the pro version (for a fee) you can also allow someone to remotely take control of your computer.
It even has an app which allows you to view the someone’s screen via your iPad.
The best thing about this is it’s simplicity. It’s easy to start sharing and just as easy to stop. So if your working on a project but can’t all be in the same room this might just be the solution for you.
