Contact Us

Have a question, found a bug, or have an idea for a new calculator? We'd love to hear from you.

Before You Reach Out

A few quick things that might save you a message:

• Trendy String's calculators don't provide medical diagnoses — for a health concern, please contact a doctor or healthcare provider directly.
• If a calculator seems to be giving an unexpected result, try refreshing the page first — most issues clear up with a simple reload.
• We don't currently offer a mobile app; all our tools work directly in your mobile or desktop browser.

Suggest a Calculator

If there's a health or wellness calculator you wish existed, tell us about it — we're always looking to expand our tool library based on what people actually need.
