## What is CubTutor?

The fight over screen time doesn't have to be a fight.

CubTutor doesn't take the phone away. It puts a few questions in front of it. Your child opens the app they were going to open anyway — it pauses, asks a couple of questions, and play continues once they answer. The practice happens because the phone asked, not because you did.

Nothing to negotiate. Nobody to nag. The rule is simply there, every day, and it does not need you standing over it.

WHAT CHANGES AT HOME

- You stop being the one who says no
- Practice still happens on the days you are busy, tired, or not there
- Screen time still happens too — your child earns it a few minutes at a time
- No confiscated phones, no timers for you to police, no bargaining at bedtime

YOU SET THE TERMS

- Which apps pause, and which are left alone
- How many questions unlock play, and how long the reward lasts
- A day off whenever you want one — it switches back on by itself
- Pause everything, or lift it, from your own phone, wherever you are

WHAT YOU SEE

- What your child has been practising, by subject and topic
- Which questions they got wrong, so you know what is actually hard
- How the week has gone

SUBJECTS

Math from kindergarten through grade 12, including Pre-Algebra, Algebra 1, Geometry, Algebra 2, Pre-Calculus, Calculus and SAT Math Prep. English, science and social studies for grades K-8. Questions match your child's grade, and you can change it any time.

IF YOUR CHILD HAS A TUTOR

Optional, and most families do not. If they do, and their tutor uses CubTutor, the questions become the ones that tutor set — the exact things they worked on this week — and the tutor sees which ones were missed. Everything above works the same either way.

WHAT IS FREE, AND WHAT IS NOT

Grade-level math is free for every child, for as long as you like. A Practice subscription unlocks English, science and social studies, the advanced math tracks, and shorter gaps between quiz breaks — for one child, two kids, or three or more, billed yearly through your Apple ID.

Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in your Apple ID settings.
