About
Summi turns math into a game. For your child it's playing; for you it's practice. From counting and times tables to fractions, decimals, percentages, money, time and measuring, for Pre-K to 6th grade. Every child gets questions at their own level, in a world that suits their age.
The download is free. To play, you make one purchase in the app: $14.99 per family, for all your children. No subscription, no ads, and nothing to buy inside the game.
THE MATH IS THE GAME
A world full of islands, on the map or in 3D with your own boat, with a daily mission at your child's level and a boss battle at the end:
• Times Arena: every right answer is a hit on the monster.
• Fraction Fort and Pizza Bay: fractions you can see.
• Clock Tower, Little Shop and Workshop: tell the time, pay in dollars and cents, fix robot Summi's mistakes.
MULTIPLICATION
Multiplication facts that stick: every times table up to 12 × 12, at your child's own pace. You can see in the parent area which facts are solid and which still wobble.
PRE-K TO 1ST GRADE: THE PLAYGROUND
Summi reads everything aloud and your child taps big pictures, so no reading is needed yet. Counting, adding and taking away with the bus, shapes and patterns. A round is short, with stars and then a sticker.
GOT IT WRONG? SUMMI EXPLAINS
A mistake never costs coins. Summi shows what went wrong, using your child's own numbers, explains it step by step and then gives a similar question to try alone.
PLAY TOGETHER
Brother against sister, or your child against mom or dad. On one tablet or each on their own device, you race live to the finish, each at their own level. Friends from other families are off by default and can only join after a parent approves them. Children can't chat.
COLLECT AND GROW
• 32 brainrots to catch: silly creatures with a Dutch twist. Rather not? One switch in the parent area.
• Their own avatar, a base camp and a pet that grows up with them, from egg to dragon.
• Badges, stars, levels and a daily streak.
PRACTICE FIRST, THEN THE ARCADE
The games are a reward, not a lesson. Daily goal done? Then your child earns tickets for nine games, such as Summi's Wonder World, Crystal Smash, Rolling World and Magic Mosaic. Each go costs a ticket, and you decide how many tickets there are each day.
IT ADAPTS
Summi keeps track of each skill and picks the next question to match. Two wrong in a row? Then a smaller step comes first. Summi follows the Common Core math standards for each grade, but it isn't a school program.
WHAT YOU SEE AS A PARENT
The parent area is calm, with no game elements:
• progress for each child and each skill, in plain English
• mistake patterns with an explanation, and a tip for home
• tasks: set something up yourself, such as the 7 times table
• how long and on which days your child played, and a short summary by email every week
PRIVACY
Your child plays with just a nickname and their grade: no surname, photo or email address. No ads and no trackers. The data is stored on servers in the EU, and you can delete your account in the app itself.
Summi needs an internet connection.
WHO MAKES SUMMI
I'm Michel, a programmer and dad in the Netherlands. I made Summi for my own children: practice had to feel less like homework and more like play. There's no big company behind it. A question, or found a mistake in a question? Email summigame@stormzaak.nl.
