Contact
The fastest way to reach me is email:
I read every message and reply within 48 hours, usually faster.
What I'd love to hear
- A calculator you wish existed
- A bug, miscalculation, or typo on an existing one
- A formula you think I got wrong (with a source if you have one)
- A partnership, press, or collaboration request
What I can't do over email
I can't give you personal financial, medical, legal, or tax advice. The calculators on this site are reference tools, not professional consultations. If you're making a real decision, please consult a qualified advisor.
For everything else — I'm listening.
