Glo-CALCULATO

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.
