Device Tester is a free Pocketool tool that shows which mouse and keyboard events your browser actually receives, plays test tones through your speakers or headphones, and checks your microphone and webcam. Raw test data stays in your browser: no account and no upload, and only the microphone and webcam checks ask for permission.

Device Tester 是口袋工具的免費裝置測試工具，讓你看清楚瀏覽器實際收到哪些滑鼠與鍵盤事件，把測試音送到喇叭或耳機，也能檢查麥克風與視訊鏡頭。原始測試資料只留在你的瀏覽器：不需帳號、不上傳，只有麥克風與鏡頭的檢查會請求權限。
