NO ADS. Nine math worlds, one squishy teacher, and a board game your kid already knows how to play. Your child's squishy puts on a costume and teaches math out loud. Your child does every step with their own fingers — taps each apple, fills each piece of chocolate, fuels the rocket a tenth at a time — then answers five questions. Four right and the skill goes up a level. THE LEARNING CENTER: 9 WORLDS, 12 LEVELS EACH • Apple Orchard — counting: count to 20 by touching, count on, what comes next, skip count by 2s, 5s and 10s up to 1,000. • Balloon Fair — adding: count on to 20, then add up to 1,000 in hops of hundreds, tens and ones. • Pirate Cove — taking away: coins walk the plank; count back in hops up to 1,000. • Cookie Bakery — times: trays of cookies are equal groups; count by 2s, 3s, 4s; times tables to 12 × 12. • Pizza Party — dividing: deal slices onto plates so everyone gets the same; division facts to 144 ÷ 12. • Building Site — shapes: circle to octagon, sides and corners, solid shapes, a cube's faces and edges, distance around, squares inside. • Chocolate Factory — fractions: halves to eighths, compare, equal fractions, add and take away, a fraction of a number. • Rocket Range — decimals: tenths and hundredths, place value, compare, add and take away, times 10, rounding. • Mystery Manor — missing numbers and equations: 3 + ? = 7, times before plus, brackets, then n + 4 = 9 and 2n + 1 = 9 on a balance. STARTS WHERE YOUR CHILD IS • A one-minute check finds the right level in every skill, then gets out of the way. • Each world opens at the right age: taking away at 6, fractions at 7, times and equations at 8, decimals at 9, dividing at 10. Younger kids see "When you're older". • Miss one? The squishy shows the working for that exact problem, then moves on. • The board game and flashcards size their numbers to your child's levels, and push a little harder the further into a game they get. A small tag shows a parent the level. MORE WAYS TO PRACTICE • Story Trail: math as tiny stories with your squishy as the hero. The app picks the numbers; the words come from Apple's on-device model or a built-in word bank. • Flashcards: five right in a row steps up, three wrong steps down. After a miss, a hint says the problem another way (on devices with Apple Intelligence). • Squishy Match: 20 levels. Drag a path through squishies that add up to the target, from Make 5 to Make 50. • Number Slide: slide squishies on a 4×4 board; two the same join into the next number. • Squishy Fishing: answer a math question to reel in each catch. Junk and snacks pay more; a rare Golden Prize pays bonus coins, up to 1,000. • Temperature Chamber: slide Celsius or Fahrenheit and watch your squishy freeze solid or melt into a puddle. • The Trail Game: roll the die, solve a problem, hop up the trail. Two players, two ages, one board. SQUISHIES TO LOVE • Fifteen squishies in ten colors, every one made of wobbly jelly. • Coins from every right answer buy squishies and colors in the shop. • 51 badges in eight ladders, from First Hop to Master Detective. Achievements pay bonus coins. • The Playroom: tap, tickle and dance with your squishy. MADE FOR FAMILIES • No ads. No accounts. No tracking. • Everything stays on the device. • One optional purchase, behind a grown-up check: the Squishy Pack ($0.99, once) opens nine more squishies, five more colors, 5,000 coins for every player, and 15 squishy tricks to buy with coins. • Two tricks, Windy and Boo!, listen for how loud the room is. The microphone is asked for only after a grown-up allows it, and nothing is recorded. • Sound with a one-tap mute; respects the silent switch.

Verdict
The clearest difference is update cadence: Squishy Math Trail at every 2 days against KOBI's fortnightly. Squishy Math Trail also leads on rating (5.0 vs 4.7). KOBI's advantage is ratings volume (38 vs 4) and iOS requirement (15.6 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. KOBI sells 10 in-app purchases, starting at $12.99 per month and Squishy Math Trail sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Squishy Math Trail holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: KOBI has 38 ratings behind it against 4, so its average is the more settled of the two.
KOBI ships an update fortnightly, Squishy Math Trail every 2 days. The most recent releases landed on October 14, 2026 and October 24, 2026 respectively.
