For parents of Grades 6–8

You will finally know
what "screen time" taught them

Your child runs a small business. To do it well they have to work out unit costs, hold a margin, scale a recipe and find a break-even. You get a weekly report that shows exactly which of those they used, and where they got better.

What the report actually tells you

Which concepts they used

Not "played for 40 minutes" — unit cost, percentage margin, ratio, break-even, each mapped to the NCERT chapter it comes from.

Where they went wrong, and what happened next

The most useful line in the report is usually the recovery: a ₹40 loss on Tuesday, corrected to a ₹90 profit on Wednesday.

How they compare

Once enough children have played, you see where your child sits against their grade — nationally, not against a class of 30.

A question to ask at dinner

One specific question tied to what they did that week. It takes thirty seconds and it works better than "what did you learn today?".

How we handle your child's data

✅ Your child never signs up. No phone number, no email, no password, no photograph. They just play.
✅ You are the one who verifies — one code to your mobile. That is what the law requires and it is also simply the right way round.
✅ We show no advertising to children and we do not track them across other apps or sites.
✅ We do not sell anyone's data. Not yours, not your child's, not to anyone.
✅ You can withdraw consent and have the data deleted at any time by writing to us. We act within 30 days.
An honest limit. This will not raise your child's marks next term, and we will not pretend otherwise. What it does is make the maths mean something. A child who has priced their own product stops asking why percentages matter — and that changes how they sit in a maths class.

How it usually goes

1
Day one. They play for ten minutes, probably lose money, and are annoyed about it.
2
Day two or three. They fix the thing that went wrong. This is the moment the concept lands — not when they read it, when they correct it.
3
Week one. They ask you for a phone to verify, because they want their shop saved. That is when your report starts.
4
Week two. They tell you at dinner why a 20% discount costs nearly half the profit. You did not have to ask.

Questions parents ask

Is it really free?The game is free — two shop days every day, plus a daily challenge, forever. A paid Parent Pass adds unlimited practice and the full weekly report. Your child is never blocked from playing.
How much screen time is this?About 10-20 minutes a day by design. There is a daily limit built in, deliberately — we would rather they came back tomorrow than played for three hours today.
Which grades is it for?Grades 6 to 8. The game starts at a different level depending on the grade you tell us, and adapts from there to how quickly they learn.
Is the maths aligned to our syllabus?Yes — NCERT, chapter by chapter. Unitary method, ratio and proportion, comparing quantities, linear equations and data handling. The Learn section shows each one.
My child is not interested in maths at all.That is who this is built for. Nothing on the screen looks like maths until after they have already used it.
