Have a bug to report, a device that doesn't calibrate correctly, a feature idea, or a general question? We read every message.

What to include

If you're reporting an inaccurate measurement or a calibration issue, it helps to mention your device model, browser, and which calibration method you used (Auto-Detect, Screen Diagonal, or Credit Card).

This is a small, independently run tool with no live chat or phone support, so email is the fastest way to reach us, and we typically respond within a few business days.
