Sostieni Katrina

Hi, I’m Katrina. I build small, practical web tools that help people solve specific everyday problems, calculators, converters, timers, and simple utilities.

Most of my tools are free to use. If one of them saved you time, helped you make a clearer decision, or was simply useful, you can support my work with a small coffee.

Your contribution helps cover hosting, data, maintenance, and the time I spend improving these tools, writing clearer explanations, and keeping them accessible without adding too many distracting ads.

Thank you for supporting independent tools.
