About AuraTech

AuraTech is a small collection of free, fast online calculators. We build single-purpose tools designed to give you a precise answer in seconds, without sign-ups, clutter, or unnecessary steps.

What we build

We started with the Age Calculator and are gradually adding more everyday tools. Every tool on this site runs entirely in your browser — no data you enter is sent to or stored on our servers.

Why it's free

AuraTech is supported by advertising, which lets us keep every tool free to use with no account required. See our Terms & Privacy Policy for details on how ads and cookies work on this site.
