CubTutor guards the apps you pick on your kid's iPhone. A question at their grade level opens them — for exactly the minutes you set. Parents set the rules, tutors shape the questions, schools raise money.
No trial countdowns. Basic math stays free for as long as you use it.
Pick the page that's about you.
Stop being the screen-time police. The phone says no now — until the question is answered.
For parents →Your questions run on your students' phones between sessions. Free for tutors, and you earn a share.
For tutors →A fundraiser that runs itself. Every family that joins through your page earns your PTO money — every year.
For PTOs & PTAs →Daily practice for every family, and a fundraiser the school keeps. Talk to us about your district.
For schools →On your own phone: choose which apps wait behind questions, how many questions a round is, and how many minutes of play a correct round earns.
When your kid opens a guarded app, a question at their grade level appears instead. No "ignore" button — answering is the only way through. Calls always work.
The apps open for the window you chose. You see daily practice, accuracy by topic and streaks on your phone — without supervising a thing.
Basic math is free. The full plan adds advanced math tracks, English, Science and Social Studies — sized for 1, 2 or 3+ kids. Subscriptions are made from the parent's phone, never the kid's.
Set it up in a few minutes — pick the apps, set the minutes, hand the phone back.
