Quick Answers Before You Write
How fast do you reply?
We usually respond within 24–48 hours. WhatsApp messages often get answered faster during working hours (Pakistan Standard Time).
The calculator gave an unexpected result — what should I include in my message?
Please send the exact formula you typed (copy-paste it), which mode you used, and the result you expected. That’s everything we need to reproduce and fix the issue quickly.
Can I suggest a new feature or a new calculator?
Absolutely — feature suggestions are our favorite emails. Several current features, including batch comparison, came directly from user requests.
I found a mistake in an article. How do I report it?
Email us with the page link and the correction. We verify against authoritative sources and update promptly under our Corrections Policy.
Do you store my form data?
No. The form on this page simply opens your own email app with the message pre-filled — nothing is saved or tracked on our servers. See our Privacy Policy for details.
