What to include, by reason

Bug report
Include your device, browser, and OS (e.g. "iPhone 14, Safari, iOS 17"), whether you were in Sensor or Manual mode, and what you expected to happen. A screenshot helps.
Feature request
Describe the measurement you were trying to make and where the tool fell short. Concrete use cases are more useful than general suggestions.
Privacy or data question
Ask about anything covered in the Privacy Policy, including what little the site does and doesn’t collect.
Everything else
Feedback, press, partnership questions — the same address reaches the same person.

This is a one-person site, so replies aren't instant — real questions do get read and answered. For how any message you send is handled, see the Privacy Policy.
