Why a fast microSD card crawls in a cheap reader
A fast microSD card can be limited by its reader, port, or adapter. Test read and write speed, then find the bottleneck without risking your files.
Is TooLab.io free?
Yes. Every test is free, there is nothing to install and you don't need an account.
Are my camera and microphone recorded or uploaded?
No. The picture and the sound are processed in your browser and never leave your device. A photo or a recording stays in its window until you choose to save it.
Can I run several tests at once?
Yes. Each test opens in its own window on the desktop. You can move, resize and snap the windows side by side, for example the camera next to the microphone.
Which browsers work best?
Recent versions of Chrome and Edge support every test. Firefox and Safari run most of them, but a few, like the battery meter, need features they don't offer.
