EquatIO is a freemium/premium product, which means that there is a free version and a paid version. The free version gives you access to all key features that enable you to make math digital, while the premium version offers additional features that take digital math to the next level.
To see what's included, please see What's free vs what's premium? (scroll down to See what's included on that page)
In order for you to test out the premium version before purchasing, we offer a 30-day free trial of all premium features when you first install EquatIO.
Within the extension, you will see a countdown in the bottom left-hand corner, which starts midway through your 30-day trial. Please refer to this countdown to keep track of how much time you have left within your premium trial.
Once the 30 days are up, you will still have unlimited access to all of the free features listed above. If you would like to upgrade your subscription to continue using the premium features, you can do so in the Texthelp Store. A premium subscription gives you access to all premium features for one calendar year.
