About Talverlator
Last updated: August 4, 2026
Talverlator is a free, browser-based utility app at talverlator.com. It combines three tools people reach for every day: a scientific calculator (with optional graphing), a multi-counter tallier with optional tally-mark display, and a converter for measurements, number bases, angles, and colors.

How the tools work
Calculator. Evaluate arithmetic and scientific expressions, switch degree/radian/gradian modes, use permutations and combinations, and open graph mode when you want a visual check.
Tallier. Keep several named counters, sort them, show classic tally marks, and track a running total—handy for games, classrooms, and inventory spot checks.
Converter. Convert length, weight, temperature, volume, area, and time; translate binary/octal/decimal/hex and angle units; and map common color models including RGB, HEX, HSL, and CMYK approximations.
