About ApexCheck
ApexCheck provides focused browser-based checks for common mouse, keyboard, display, camera, microphone, speaker, and text problems.
What the tools do
Each checker presents the browser events or measurements available to the page. The tools support practical comparison and troubleshooting, not laboratory calibration or professional certification.
How to interpret results
A failed check does not automatically prove hardware failure. Permissions, system settings, drivers, extensions, hubs, and vendor utilities can affect what reaches a web page. Compare browsers and ports before replacing hardware.
Local processing
Mouse, keyboard, camera preview, microphone level, speaker tone, display pattern, and word-count input are processed in the browser unless a page clearly states otherwise. ApexCheck does not upload camera frames, microphone audio, or text entered into the counter.
Editorial approach
Instructions describe observable browser behavior and note relevant limitations. Pages are reviewed when tool behavior changes, and corrections can be submitted through the contact page.
How to report a problem
Include the tool name, browser, operating system, and reproduction steps. Do not send sensitive recordings or personal documents.
