Kani is mental-arithmetic practice your child will open on their own — and a parent view that tells you, in about ten seconds, whether this week went anywhere.
No card to start. The placement check needs no account at all.
Nobody is asking you to teach abacus. You just get enough visibility to ask the right question at dinner.
Open the parent view and the week is right there: how many minutes a day, which days got skipped, how long the streak is, and what they worked on most recently. No digging.
A score tells you nothing you can act on. The dashboard breaks practice down by accuracy and by skill, so “she is bad at maths” turns into “she loses the ten-complements once the numbers reach three digits”.
The hard part of daily practice is not the maths, it is the second day. Kani is built as a game economy — coins, badges, boss battles, matches against friends — so the streak survives without you standing over it.
This is the part nobody warns you about, and it arrives sooner than you would expect.
In the first months you can check everything — the sum is on the page and so is the answer. A year in, they are holding a four-row addition in their head and writing down a single number. There is no working to mark, the answers come faster than you can verify them, and “did you actually get that right?” becomes a question neither of you can settle.
You never have to do the arithmetic yourself. Each question is scored as it is answered, and what reaches you is the part you can act on: accuracy and which way it is trending, which skills are solid, and which level keeps slipping. Thirty answers are checked before the tablet is closed.
It is also why a weak spot arrives already named — “ten-complements at three digits” — instead of “he is just being careless”.
The app and the parent view speak 28 languages, with right-to-left Arabic, Urdu and Central Kurdish built in rather than bolted on. Number narration is English everywhere — one voice set, deliberately.
Runs in any browser on a phone, tablet or laptop. Native Android and iPhone apps exist if you would rather have an icon — but nothing needs installing to start.
The free placement check takes about five minutes, needs no account, and puts your child on the correct rung of the nine-level ladder instead of guessing from their age.
A daily practice allowance, the placement check and the virtual abacus cost nothing. A subscription lifts the daily cap once your child is practising more than the free tier allows.
Up to eight profiles on one device, each with their own level, streak and coins. Siblings pass the same tablet around without treading on each other’s progress.
No advertising anywhere in the app, and no ad profiles built against what your child does. We ask for a nickname, an avatar and a language — not a school, an address or a photo.
Set up a profile in under a minute, run the placement check, and see the first session on your dashboard before bedtime.
