Hey everyone — I built UpShark.org because I was tired of slow, cluttered “utility” sites full of pop-ups and trackers. This is my attempt to fix that: a growing constellation of clean, pro-grade tools for everyday use, finance, cooking, time, conversions, and more. (WIP obvs!) Everything runs locally in your browser, with no logins or data collection. It’s built to be fast, private, and useful. Would love your thoughts, ideas for new tools, or any bugs you spot. Thanks for checking it out!
