Hey Zak, the easiest way to get your staff using the app is to get them to click the 'get the app' link that will be at the top of their roster email.

This will then prompt them to create a password and download the app.

The video here also explains this process in more detail: http://help.tanda.co/get-started-with-tanda/introducing-the-new-tanda-app

Alternatively you can simply send them the link below. Once they have downloaded the app they will just need to click the 'I don't have a password' button to create one before they can login.
