Math Game vs Rondo

Play with animal buddies, and before you know it, you're better at math and quicker to react. Math Game is a 60-second number adventure with animal buddies by your side. Angula the little fox lives in a room on your home screen, growing and learning as you answer correctly. Tap to start with three lives. Levels get harder as you improve. Just open and play—no setup screen. 【ANIMAL BUDDIES PLAY ALONG】 • Tap or swipe Angula on the home screen to see it respond. It finds things to do on its own, too. • The more answers you get right together, the more it levels up and learns. • Aim for 100% Energy daily: play a round and give snacks to perk it up. • Finish 2 rounds to play 1 mini game (up to 3 a day). Earn gems to exchange in the House for furniture, toys and snacks. 【60 SECONDS TO QUICKER REACTIONS】 • Play while waiting for a ride, taking a break or winding down for bed. • Correct answers score points, back-to-back correct answers score double, and the final 10-second alarm makes you push for more. • Results show missed questions and their answers to help you go faster next round. 【COLLECT 15 ANIMAL BUDDIES】 • Flip Buddy cards to meet new animals. Each has 12 cards; collect the set to have it join your rounds and hold up O/X signs. • Your card in Me tracks total correct answers, climbing from Rookie, Rare and Epic to Legendary and Mythic. 【DAILY GOALS, STREAK REWARDS】 • Each game mode has a daily goal, always just a little beyond yesterday's. • Streak days 2, 3, 7, 14, 30 and 100 bring card-flip tickets, new buddies or badges. • The weekly leaderboard resets every Monday and adds up every round's score. Play more to build your total. The high-score leaderboard puts your best round alongside players worldwide. 【GROWN-UPS CAN JOIN IN】 • A long workday or a lot on your mind? Take 60 seconds to focus on a game, switch gears and unwind. • Play the same level as your child and compare scores, or take on the global leaderboard yourself. • After a round, pet your fox on the home screen and relax as you watch it go about its day. 【THE RESEARCH BEHIND THE PLAY】 • Recall: working out an answer helps retention more than rereading (Roediger & Karpicke, 2006, Psychological Science). Every question is a chance. • Little and often: spaced sessions aid retention (Cepeda et al., 2006, Psychological Bulletin; meta-analysis). Play 60 seconds a day. • Speed: fluent basic arithmetic predicts later math performance (Geary, 2011, Developmental Psychology). Timing and immediate feedback help build fluency (Codding, Burns & Lukito, 2011; meta-analysis). • Feedback supports learning (Hattie & Timperley, 2007, Review of Educational Research). See right or wrong instantly and find the correct answers to any misses in your results. • Game elements show a moderate positive effect on learning (Bai, Hew & Huang, 2020, Educational Research Review; meta-analysis). Buddies, mini games and streaks invite another round; questions build familiarity. • Growing challenges: levels rise automatically, keeping the next step achievable with a little effort. 【PEACE OF MIND FOR PARENTS】 • No login or account. Open and play; the game remembers your device automatically. • No ads, in-app purchases or chat. Earn gems only by playing, never by paying. • Leaderboards show built-in animal avatars, with report and block options on every row. • For elementary-age kids and up, and adults who want to unwind and sharpen their reactions. One round a day: fun for kids, a breather for grown-ups.

Rondo turns the counting numbers into a quiet, hypnotic dance. Every number from 1 upward is drawn as a factorization diagram: nested rings of colored dots that show, at a glance, how that number is built from its prime factors. 6 is two groups of three. 12 is three groups of four. Primes can't be split, so they shimmer alone. Then the diagram melts and re-forms into the next number, and the next, an endless looping dance of arithmetic. It's equal parts math toy, teaching tool, and ambient art. WATCH, OR EXPLORE • Let it play for a calm, continuous dance from one number to the next • Tap to pause, drag to scrub to any number, or step one at a time • Speed it up, or slow it right down • A gentle haptic tap each time the dance lands on a prime • Follow any number down its Collatz orbit, and watch it fall back to 1 HEAR IT • Every number sings its factorization: a prime is a single pure tone, a composite a chord of its prime factors • On by default, off whenever you like POINT YOUR CAMERA • Aim Rondo at any printed number and watch its diagram bloom over the page, in augmented reality • Summon a number's diagram into the room, then walk around it • Street signs, receipts, book pages: factor the world around you EVERY NUMBER HAS A STORY • Tap any number to see what makes it special: whether it's prime, a perfect number, a power, and more • Collect the special numbers you find in the Field Guide SEE THE MATH • The current number and its factorization, always in view • Full VoiceOver support and a spoken read-out of each number and how it factors • Save the numbers you love to Favorites, and share any diagram as an image ON YOUR HOME SCREEN AND WRIST • Widgets that turn today's date into factorization diagrams, across the Home Screen, Lock Screen, and StandBy • A factorization calendar for the month or the current week • A widget for a number you pin, and a stepper widget you tap to walk one number at a time • An Apple Watch app: scrub through the numbers with the Digital Crown, with the same prime haptics • Ask Siri for a number, or add Rondo to a Shortcut • An optional nudge on days whose number is itself worth a look MAKE IT YOURS WITH RONDO PRO A one-time unlock, never a subscription. The full dance stays free. Pro is for going deeper: • New color palettes, backgrounds, and color styles • Layout options for how the rings nest and order themselves • A living clock face that factors the time • Number sequences: count by multiples, primes only, Fibonacci, and more • The full instrument: tune the scale, voice, and space of the sound • Hear any number's story narrated aloud, in your choice of tone CALM BY DESIGN No ads.

A LOVING HOMAGE Rondo is a faithful tribute to Brent Yorgey's factorization diagrams and Stephen Von Worley's animated "Factor Conga," built natively for iPhone, iPad, and Apple Watch. The diagrams honor their work; the sound, the augmented reality, and the stories are Rondo's own. Full credits are in the app.
