Pricing

Our annual subscription is just $10 USD per year. There is no automatic renewal, but we will send you a reminder before your subscription expires.

I want to help students — that’s why it’s so affordable. Your payment helps me maintain the servers and infrastructure, and continue building new features to support your learning.

If you are a teacher and interested in a group package, I would love to hear from you. Please get in touch so we can discuss options.

There are no refunds, since the only way to know if the system is truly useful for you is to use it over several weeks.

If you have any questions, please contact us.
