Calculator requests, bug reports, embed questions: we read everything.

Email us at hello@calcaholic.com.

Things we especially want to hear about:

• A calculator you wish existed. The more specific (or more obscure), the better.
• A wrong answer. If a calculator ever gives a result you can show is incorrect, we want to know immediately.
• Embedding. All our calculators are free to embed via the "Add to your website" button on each page. If you need a custom size or have it working somewhere cool, tell us.
