About this app

Why shouldn't a calculator have everything you need? JellyCalc is a wobbly, jelly-animated 3D calculator for Android. It combines a scientific and graphing calculator, over 160 unit conversions and a full daily hub of weather, news, world clock, market quotes and holidays, all wrapped in a design made to be played with.


🎨 What makes JellyCalc different

Calculator apps are rarely designed for delight. JellyCalc starts there. Translucent glass panels, colorful layered cards, soft spring-physics wobble and depth-shaded 3D button reactions answer every touch, backed by haptic feedback and playful sounds. Tap a button several times in a row and a hidden Lottie animation may appear, one of many small surprises scattered through the interface. Seventeen color layouts plus adjustable fonts, sounds and haptics let you tune the whole feel.


👤 Who JellyCalc is for

Students and engineers: trigonometry, logarithms, graphing

Cooks: cups to grams, ounces to milliliters, oven temperatures

Travellers: time zones, holidays abroad, shoe, clothing and ring sizes

Shoppers and savers: tips, discounts, VAT, loans, compound interest

Anyone who would rather open one app each morning than a dozen

Anyone who cares how an app looks and feels
