Unlimited, scrollable calculation history is here, now with a built-in entry counter so you can easily review, revisit, and track past calculations.
Glo-CALCULATO is a fully original scientific calculator wrapped in a continuously rotating rainbow glow - built from the ground up by De'Jahn Bell and FOOD4THOTH.
Every button pulses with a full-spectrum rainbow border. The calculator body swirls with color. A hand-drawn smiley face greets you on launch and gently fades when you start calculating - bring it back by tapping AC.

DEG / RAD MODE
Tap the DEG/RAD badge on the display to switch angle modes instantly. In DEG mode, sin(90) = 1, exactly as expected. Trig functions automatically adjust to the selected mode.
CALCULATION HISTORY
Every result you calculate is saved to a scrollable history panel above the calculator. Tap any past result to load it back into the display and continue from where you left off. Clear history any time with one tap.
COPY TO CLIPBOARD
Tap the copy icon on the display to copy your current expression or result to the clipboard. A confirmation flash shows you exactly what was copied - paste it anywhere.
HAPTIC FEEDBACK
Every button press responds with a precise haptic tap. The equals button gives a stronger pulse for that satisfying finish.
COMPLETELY FREE
No ads. No subscriptions. No in-app purchases. No account required. Just open it and calculate.
Glo-CALCULATO is born from the creative universe of FOOD4THOTH - where math meets color, and every calculation feels magical.
