Gradation Calculator is a beautifully crafted calculator that turns every button press into a burst of living color. Powered by real-time fluid simulation rendered directly in Metal, the background flows and shifts with vibrant gradients — reacting to every number you enter and exploding into a full rainbow when you hit equals. Now with a full scientific keypad, it's as capable as it is beautiful: switch on function mode and the same fluid canvas backs trigonometry, logarithms, powers, roots, and more. Features: • Scientific calculator — tap ƒ(x) to reveal trig (sin / cos / tan and their inverses), hyperbolic functions, logarithms, powers and roots, factorial, reciprocals, the constants π and e, parentheses, and scientific notation • Natural math notation — expressions display the way you'd write them: √2, ln(9), 3², ³√(9), log₁₀(9) • 2nd & Deg/Rad — a 2nd key unlocks inverse functions, with switchable degree and radian modes • Color themes — choose your mood with Ocean, Sunset, Aurora, and Galaxy gradient palettes • Real-time fluid simulation — smooth, GPU-powered color flow that responds to every tap • Rainbow burst on equals — a satisfying full-color explosion every time you calculate • Calculation history — review past results and tap any entry to reuse it instantly • Long-press to copy — hold the result to copy it to your clipboard with haptic feedback • Elegant minimal UI — transparent buttons float over the dynamic gradient background • Dark-mode native — designed from the ground up for a stunning dark display
