We are a group of IT professionals at AV Technologies, passionate about creating high-quality, free online tools and calculators for everyone. Our mission is to make helpful utilities accessible to users worldwide through a fast, clean, and easy-to-use platform.
This journey began in 2007 under calculators.info, and we later migrated to calculator.net in 2008. In 2025, we evolved further as TheAllTools.com.
Our tools span across four key categories:
All calculators are developed in-house, with some powered by open-source JavaScript libraries. Most of them use trusted formulas from textbooks and certified references. Calculators related to finance and health are reviewed by financial advisors and medical professionals, ensuring reliability. Fun tools like the love calculator are purely for entertainment.
Almost all of the written content is original. In rare cases, content derived from Wikipedia is used under the GNU Free Documentation License. Financial descriptions are carefully curated by our in-house finance team, while health-related content is verified by qualified doctors.
This website is proudly owned and maintained by Maple Tech International LLC and developed by AV Technologies.
