Our Story
OmniCalcX started as a solo indie project driven by a simple frustration: too many online calculators are cluttered with ads, require accounts, or just don't work well on mobile. I wanted to build something better — a clean, fast, reliable set of tools that you can trust.
As an independent developer, I build and maintain every calculator on this site myself. I continuously improve them based on user feedback and add new ones to cover the topics people search for most. It's a labor of love, and I'm grateful for everyone who uses and shares these tools.
Our Principles
- Free forever. All our calculators are and will remain free to use.
- Accurate and reliable. I test every calculator thoroughly and reference authoritative formulas and sources.
- Fast and responsive. No bloated pages or slow load times. The site is optimized to work quickly on any device.
- Privacy-first.I don't collect personal data or require accounts. See the Privacy Policy for details.
