Catculator does all your everyday meow-thmatics, but with cats. Tap the numbers, hear soft little mews, and let the cats make your sums a little more joyful. - One cat or many: fill the keypad with cats, or pick a single feline friend. - Cats that count: every digit from 0 to 9 is its own hand-drawn cat. - Sleepy little friends: the cat above your sums gently blinks, twitches and dozes as you work. - Claw-some rerolls: tap the dice to shuffle your background and cat in an instant. - A-mew-sing sounds: gentle mewing on every tap, with a tiny pitch wobble so no two are quite alike. Turn it off and on whenever you like. - Cat-titude for every mood: cream, minty, cool, rainbow, icy, forest, cutesy and dusk backgrounds. - Proper meow-thmatics: order of operations, percentages, and an undo button just in case. No accounts. No ads. No tracking. Just a happy little calculator that happens to be full of cats, made by Saskia.
