JellyCalc: Graphing Calculator

Why should a scientific calculator stop at calculations? JellyCalc is a wobbly, jelly-animated 3D calculator with a step-by-step equation solver, a graphing calculator, 160+ unit conversions and a daily hub with weather, news, world clocks, market quotes and holidays, in a design that feels alive and playful. 🎨 What makes JellyCalc different Translucent glass panels, colorful layered cards, spring-physics wobble, 3D button reactions, haptics and optional sounds. Tap some buttons repeatedly and hidden animations may appear. Seventeen color themes plus adjustable fonts, sounds and haptics. 👤 Who JellyCalc is for Students and engineers: equations, graphs, calculus and matrices Cooks: cups to grams, ounces to milliliters, oven temperatures Travellers: time zones, holidays, shoe, clothing and ring sizes Shoppers and savers: tips, discounts, VAT, loans and interest Anyone who likes many everyday tools in one playful app 🌟 Daily Summary One visual dashboard, with a free preview and Premium live updates: time, date, zodiac, "happened on this day", weather, forecast, sunrise and sunset, moon phase, holidays, news headlines, personal daily stats, market quotes and shortcuts to common apps. 🧮 Scientific Calculator Trigonometric and inverse functions, logarithms, powers, roots, factorials and constants, degree and radian modes and a timestamped history. 📐 Step-by-Step Equation Solver Every step explained, with exact fractions, roots and π and a matching graph: linear and quadratic equations, polynomials up to degree 8, systems of 2 or 3 equations, inequalities with sign charts, exponential, logarithmic and absolute-value equations, derivatives, integrals, first- and second-order differential equations, matrices (determinant, inverse, rank, eigenvalues) and complex numbers. 📈 Graphing Calculator Functions, parametric, polar and implicit curves, regions and slope fields. Sliders for parameters, f′ and f″ curves, automatic roots, extrema, inflection points, asymptotes, holes and intersections, tangents, areas, area between curves, Riemann sums, transformations and value tables. 🔓 One-Time Unlock, No Subscription Unlock the full graphing and step-by-step equation suite with a one-time Premium purchase. No subscription and yours forever, while most solver apps charge monthly. 📏 Over 160 Unit Conversions Currency, kitchen, length, weight, volume (metric, UK and US), temperature, area, speed, time, pressure, force, energy, power, fuel efficiency, data and angles, with instant recalculation and one-tap swapping. ✈️ Travel Tools World clock and time zone converter, holiday calendar for 120 countries and shoe, clothing and ring size converters. 💰 Finance Calculators Loans, compound-interest savings, investment growth and returns, time-to-target, tips and bill splitting, discounts, tax and VAT, fuel cost and unit prices. 🏠 Everyday, Date and Time Tools BMI, period and ovulation calculators, pot size, Roman numerals, area, volume and mileage; date intervals, moon phases, time arithmetic, age and pet age. Cycle and ovulation tools are estimates only, not medical advice or contraception. ℹ️ Good to know Try every Premium tool free for an hour by watching a short ad. The calculator, solver, graphing and many converters work offline; weather, news, live rates and quotes need internet. No account or sign-up required. The solver covers the equation types listed above; it is not a full computer algebra system.
