Pulse Score
Your overall browser performance score. Higher is better. It's a combined score from responsiveness, compute, graphics, and stability. Use it to compare runs on the same device, or compare browsers.
50–80: may feel sluggish
80–120: typical modern device
120+: high performance
Valid Run vs Invalid Run
Valid Run: the test ran in the foreground and results are trustworthy.
Invalid Run: the tab was hidden/backgrounded or the run was interrupted. Browsers throttle background tabs, so numbers won't be accurate.
Confidence
How consistent your results were across repeated runs.
- Excellent: stable, repeatable (trust the score)
- Good: minor variation (still useful)
- Variable: something is causing fluctuations (battery saver, thermal throttling, heavy background apps, low power mode, lots of tabs)
Categories Explained
- Responsiveness: How quickly the browser reacts to UI changes. Affects scrolling, typing, clicking, and how "snappy" sites feel.
- Compute: Raw processing speed for typical web work. Impacts heavy pages, dashboards, crypto apps, and sites doing lots of calculations.
- Graphics: How smoothly your browser can draw moving visuals. Affects animations, charts, canvases, and interactive sites.
- Stability (Jitter): How steady your browser's timing is. High jitter can make everything feel laggy even if the device is powerful.
Profiles & Duration
Profile (Auto/Small/Medium/Large): Choose how heavy the test should be. Auto is recommended—Pulse picks a good workload for your device. Small for older phones, Large for fast desktops.
Duration (Quick/Extended): Quick is fastest, good for a quick check. Extended is more reliable (better for comparisons).
