Free online calculators and classroom tools – no sign-up, no tracking
Hi, I’m Max from Mainz, Germany. I build KeypadLab (keypadlab.com) in my spare time: free online tools that just work. A scientific calculator, a percentage calculator, a VAT calculator, a random wheel, a team generator, a classroom timer, a word counter and more, available in several languages.
Everything is free, with no sign-up. Whatever you type stays in your browser. Teachers can even embed the tools in their own class pages.
Your coffee covers hosting and helps me add new tools and languages. Thank you for your support! ☕
