What's great
Finally, a tools website that just works! I love how fast it loads — no waiting, no popups, no distractions. The layout is so minimal and easy to navigate that I can find any calculator I need in seconds.
It’s refreshing to see something built with simplicity and speed in mind. Definitely my go-to for quick calculations now.
