Test and fix your speakers, mic, camera and screen.
9 toolsA closer look at every device tool and when it helps.
Speaker Cleaner
A low, pulsing tone shakes the speaker so trapped water can work its way out — no app to install.
Speaker & Headphone Test
Quick checks for swapped channels, missing bass and rattles — on speakers, headphones or earbuds.
Microphone Test
Check your mic before a call or recording — level, the right device and how you actually sound.
Webcam Test
See exactly what others will see, with honest numbers for resolution, frame rate and light.
Screen Test
Handy before you buy a used phone or laptop, or when something on the screen looks off.
Mouse Test
Double-clicks on their own, drags that drop files halfway, a wheel that jumps — see it happen and know why.
Keyboard Test
Press every key and see which ones work, which type twice and which combos your keyboard can't handle.
Gamepad Test
Find stick drift, dead buttons and weak triggers before you blame the game.
Device Performance
Real speed numbers for this device, and whether battery mode or heat is holding it back.
