Device Performance Check
A quick, honest read on your device's CPU, memory, and crypto performance — with a composite score and per-test breakdown.
Composite score
—
Higher is better
What do these numbers mean?
What does this measure?
Real CPU work (integer + float), memory bandwidth, and hardware crypto speed — the things that actually matter for app responsiveness.
Higher score = better?
Yes. The score is normalised inverse of total benchmark time. Roughly: <200 slow, 200-400 OK, 400-800 fast, >800 excellent.
Why is my desktop slower than my phone?
Modern phones are surprisingly fast. Background apps, low-power mode, or thermal throttling can also pull desktop scores down.
Is this safe to run?
Yes — it runs for about a second and only uses standard browser APIs. Nothing leaves your device.
