About HandyToolSpot

HandyToolSpot is a growing collection of small, single-purpose online tools: calculators, generators and converters that do one job well and get out of your way.

What we believe

• The tool comes first. Every page opens with a tool that works the moment it loads, no sign-up, no downloads.
• Your data stays with you. Every calculation runs inside your browser. Nothing you type is uploaded or stored on a server.
• Explain the math. Each tool shows the formula or method it uses, and where numbers come from outside sources, we cite them.
• Fast and clean. Pages are small, load quickly on any phone, and avoid clutter.

Accuracy

We check every tool by hand against worked examples before it goes live. If you spot a mistake or have an idea for a new tool, we would love to hear from you on the contact page.
