Autograph Maths is now part of the Complete Maths family and version 5 is available to download for free for Windows computers, laptops and tablets. There is no Mac version of Autograph Maths.
Go to https://autograph.completemaths.com/#download – if you haven’t got a Complete Maths account you’ll need to create one, so choose “I am a student” on the right hand side.
Fill in the form and click “Submit”. A verification code will be sent to the email address you supplied, enter this and you will then be able to download the software.
Although the software asks you to log in to your Complete Maths account when you first run it, this does not appear to be a requirement – you can simply create a new page and carry on using the software.
