Request a Tool

Challenge accepted – request your dream calculator, converter or simulator.

Share Your Idea

Got an idea for a calculator, converter, estimator, simulator – or something totally unique? I’m always looking for smart, useful (or fun!) tools to add to SwissKnifeCalculator.

How it works:

  • Describe the tool you’d like – what it should do, which inputs and outputs you imagine.
  • If possible, tell me who would use it (students, engineers, DIYers, etc.).
  • I review all requests and try to build the ideas that help the most users.

I can’t promise every idea will go live, but detailed requests really help me prioritise what to build next.

I’ll only use your email to reply about your request – no newsletter, no spam.

The more concrete your example (numbers, units, steps), the easier it is to build your idea.
