About TapCoverage

TapCoverage records the cells reached by touch pointer events inside a browser grid. It can show simultaneous contacts and a separate mouse-only check, all locally.

One free tool, one clear task

The tool and its explanations are free to use without an account or subscription. The free guide is intended for email delivery. Guide signup and email delivery are not available yet. This site does not currently collect names or email addresses through the guide form.

Interpreting the result

Coverage is a record of browser events, not a hardware diagnosis, calibration, pass/fail result or certification. Browser and operating-system gestures can prevent events from reaching the page.

Resources and support

Resource links are optional and do not unlock tool features. Affiliate links, when present, are marked with a commission disclosure and may earn this site a commission from qualifying purchases or sign-ups. An ordinary resource link does not imply an affiliate arrangement. Optional one-time tips may be offered when a payment connection is available.
