Where will my purchase work?

Buy from this website : Use on all your PC, Mac, and Android devices.

: Use on all your PC, Mac, and Android devices. Buy inside the iPad app : Use on all iPads connected to the same iTunes account.

: Use on all iPads connected to the same iTunes account. Buy inside the Android app : Use on all Android devices logged into the same Google Play account.

We wish the website unlock worked on the iPad too, but Apple has a rule that forces it to be a separate purchase.

Unfortunately, neither Apple's "Family Sharing" nor Google's "Family Library" features work with in-app purchases. For the iPad, you can temporarily sign into your family member's tablet and "Restore Purchase". For Android, an unlock key purchased from this website will work on all your family member's devices.

Because of all the limitations on in-app purchases, their purchase price is a little lower than an unlock key from this website.

Synthesia in the Classroom

Get group keys with volume discounts.

Synthesia is licensed on a per-seat basis to educational organizations like classrooms and private studios. Be sure to pick "Educational Organization" on the ordering page. Any volume discount you're eligible for is applied automatically.

Classroom keys start at the same price as personal home-use keys, and eventually become even cheaper with the volume discount.

If you'll be using Synthesia in your classroom, we have a Classroom Guide to help you get things up and running in a networked environment.
