Ready Nothing runs until you press Start.

Browser-only test: Nothing runs until you check the consent box and press Start. It does not install anything, read files, upload results, or call external APIs. On phones and laptops, start low and stop if the device gets too hot, too slow, or uncomfortable.

What it means

Device feel Idle

Start a test to see whether the device feels normal, busy, laggy, or overloaded.

FPS meaning Graphics test ready

Around 60 FPS feels smooth. Around 30 FPS is usable. Below 20 FPS can feel choppy.

Graphics area

This animation runs during the test when graphics checking is enabled.

Privacy and safety

Runs only after visible user consent and pressing Start.
Uses browser workers for CPU work so Stop can still respond.
Uses rough real-life comparisons to explain load. They are estimates, not exact hardware measurements.
Does not collect, upload, fingerprint, mine crypto, or call external APIs.
Automatically stops at the selected duration and clears allocated memory.
