Questions & Answers
Practice, the 10-level Challenge and mistake review are free — no account, no ads, no tracking. Live Race multiplayer and custom printable worksheets are part of Supporter. Every new family gets 3 months of Supporter free at sign-up.
One membership covers up to 2 parents and 2 children: Live Race multiplayer, the custom worksheet generator (4 difficulty ranges, 5–100 questions, US Letter/A4, optional answer page), and every future Supporter feature. All plans unlock the same features.
$4.99 per month, $49 per year (about $4.08 per month — $10.88 less than twelve monthly payments), or $149 once for lifetime access.
Create a free parent account and your family automatically receives 3 months of Supporter — Live Race and custom worksheets included, no card required. It is one trial per family, starts at registration and ends automatically. Nothing is charged when it ends.
Live Race and custom worksheets lock. Practice, Challenge, mistake review, your child profiles and all learning data stay. You can subscribe at any time to unlock the paid features again.
Yes — they renew automatically until you cancel. You can cancel from your Parent Center at any time, and your access continues until the end of the period you have paid for. The Lifetime plan is a single payment and never renews.
You do not need an account to play Practice or Challenge. The membership and child logins live on a parent account. In the Parent Center, a parent creates up to 2 child accounts with a username and password (no email). Children choose Student sign-in, then play on their own device.
The family owner can invite one more parent by email from the Parent Center. They sign in with that email or Google and join the same family, sharing the same membership. Each family has 2 parent seats and 2 child seats.
Choose a plan above; checkout opens on Waffo Pancake's secure hosted page. Waffo acts as our merchant of record, so card details and sales tax are handled there — we only receive the order result and never see or store your card number. Monthly and yearly renewals can be cancelled anytime in the Parent Center; the one-time Lifetime purchase never renews.
Write to [email protected] and we'll fix it or refund you.
To keep generation fast for everyone, each family is limited to 20 worksheet downloads per 10 minutes — far more than a family needs in a day.
A subscription or lifetime purchase is not a promise that the service runs forever. If we ever have to stop it, we'll announce it ahead of time and treat paid supporters fairly.
