About ToolField

ToolField is a collection of practical online tools — built to be simple, focused, and free. Each tool is made to solve a specific everyday task without distractions.

A lot of useful tools on the web are cluttered, require an account, or push people toward paid plans for basic features. ToolField takes a different approach: build something small, build it well, and keep it free.

The project started with a single tool — the Chinese lunar calendar — and may grow into more over time.

Good tools should do one thing well. They should load fast, work reliably, and stay out of your way. Every tool in ToolField is designed with that in mind.
