GangeComing soon

Times tables that keep up with your child.

Gange practises the times tables and plus and minus with each child on their own. The facts they miss come back, new ones arrive only once the old ones stick, and they can answer by tapping, writing with a finger or saying it out loud.

Practice that adapts to each child

Not the same flashcards for everyone. Gange keeps track of every single fact for every child and picks the next questions from that.

+47×83×49+65×56×27×8

Missed facts come back

Get 7 × 8 wrong and it comes back four questions later, then again in the next rounds, until it sticks.

×1×2×10×5×3×4×9×6×7×8

New facts when the old ones stick

A child who’s struggling gets one new fact per round, one who’s flying gets five. The tables come easiest first: ×1, ×2, ×10 and ×5.

Quick means known by heart

A right answer within three seconds is one the child really knows. Slow answers get more practice, and a relaxed pace gives the youngest more time.

Tap it, write it or say it

Each child answers the way that suits them, and can switch in the middle of a round.

Big keys

The answer goes in by itself once it has enough digits. No fiddly OK button between one question and the next.

Rub outAnswer

Write with a finger

Write the number on the screen. Gange reads the handwriting on the iPhone, and a misread digit is rubbed out with one tap.

“fifty-six”= 56

Say it out loud

Say “fifty-six” and it counts. Speech is understood on the iPhone itself, and nothing is recorded or sent anywhere.

Made for the whole family

Every child, their own progress

Add each child with a name, an animal and a colour. Each one has their own facts, streak and pace, and you can pick the tables they’re doing at school.

A heat map for you

Every fact as a square, from grey (not practised yet) through red and yellow to green. Tap a square to see how often it was right and the fastest time.

Times tables, plus and minus

The 100 times facts from 1 × 1 to 10 × 10, and plus and minus within 20: what children practise from first to fourth grade. In 12 languages.

Nothing leaves the iPhone.

Your children’s names and progress stay in the app on your iPhone. Handwriting and speech are understood on the phone itself, and nothing is recorded, uploaded or shared.

  • No account
  • No ads
  • No tracking
  • No in-app purchases

No more quizzing times tables over dinner.

Gange costs $1.99, once. No account, no ads, no tracking, and your children’s progress never leaves your iPhone.

That’s all it ever costs. Every feature and every future update is included, and so are the extra app icons. No subscription, nothing to unlock later, and if something’s wrong, you write straight to Peter, who made it.

Questions

Is it a subscription?

No. Gange costs $1.99, once. There’s no subscription, no in-app purchases and no ads.

Does it need the internet?

No. Everything works offline, including reading handwriting and understanding speech. There’s no account to sign in to.

Which ages is it for?

Roughly 6 to 10, from first to fourth grade: plus and minus within 20 for the youngest, the times tables up to 10 × 10 for the older ones.

What does “quick” mean?

A right answer within 3 seconds when tapping, a little longer when writing (5 seconds) or speaking (4 seconds). Quick answers move a fact on; slow right answers get more practice. The relaxed pace gives 60% more time.

Does voice work in my language?

Gange uses Apple’s speech recognition on the iPhone itself, never a server. If your iPhone can’t do it offline in your language, Gange says so, and your child taps or writes the answer instead.

Can several children use the same iPhone?

Yes. Add as many children as you like. Each one gets their own progress, pace and tables, and the heat map shows each child separately.

Which languages does Gange speak?

English, Danish, German, French, Spanish, Italian, Dutch, Swedish, Norwegian, Brazilian Portuguese, Japanese and Korean, in the app and when answering out loud.
