About ToolsOrbit
Small, fast tools that do one job well and keep your data on your device.
What ToolsOrbit is
ToolsOrbit is a growing set of free online tools for business, marketing, writing and everyday tasks. Right now there are 10 tools, from an SMS segment counter to an invoice generator, and new ones are added regularly. Every tool is free, needs no account and shows its working: the formula, a worked example and answers to the questions people actually ask.
Why it exists
Most "free online calculator" pages are slow, cluttered and vague about how they get their numbers. We wanted the opposite: pages that load instantly, give the right answer, explain the maths and respect your privacy. The name comes from the idea of a small set of useful tools orbiting around the jobs you do every day.
Your data stays on your device
Every tool on this site runs entirely in your browser. Whatever you type into a calculator, counter or generator is processed on your device and is never sent to our servers, because there are no servers doing the work. Some tools offer to save a draft, such as an invoice you are still writing. That draft is stored in your browser's local storage and nowhere else, and you can clear it at any time.
How the site is funded
ToolsOrbit is supported by advertising. Ads keep the tools free and never influence how a calculation works. You can read exactly what is collected and how advertising cookies are used in our Privacy Policy.
Accuracy
Each calculator's logic is covered by automated tests that check the formulas against known results. Even so, results are estimates for planning and learning, not professional advice. Please read the Disclaimer before relying on a result for a financial, tax or legal decision.
