WHAT WE MEASURE

Three tests. One clear picture.

Scannio measures the parts of your device that most affect everyday browser performance.

Graphics · live render test

-
Measured frame ratetarget ≥55

- fps

Avg frame timetarget ≤18ms

- ms

Chart shows measured frame times across the 2s render. Frame rate is capped by your display's refresh rate.

Memory · allocate & sort 960k items

-
Throughputtarget ≥1.5

- M items/s

Avg batch timetarget ≤80ms

- ms

Chart shows the measured time of each of the 8 batches.

Storage · timed 8×1MB writes

-
Write ratetarget ≥25

- MB/s

Avg write timetarget ≤40ms

- ms

Chart shows the measured time of each write. Free space is estimated from the browser's storage quota.

Every number above is measured on your device during the test - nothing is simulated. Results reflect responsiveness right now and can vary with temperature, battery level and open apps.

Typical cache build-up

~4.4 GB

A rough estimate of app caches, chat media and logs a phone typically accumulates - based on how long you've used it, not a scan of your device.

Frequently asked questions

Privacy

Does ScannioApp collect or upload my data?
No. Every test runs locally in your browser using standard web APIs - nothing about your device or results is sent to a server, and nothing is stored anywhere except your own browser.
What information does the check use?
Only what any website can already see through your browser, if it's exposed at all: a graphics description string, an approximate memory hint, and battery status. None of this identifies you personally.
Do I need to install an app?
No - everything runs in this browser tab. There's nothing to download or install, and closing the tab removes it completely.
Is my score saved anywhere?
Only in your own browser's local storage, and only to remember whether you've purchased the Pro Report. It never leaves your device.

Terms

Is the Pro Report a subscription?
No - it's a single one-time purchase covering one PDF report based on your most recent check. There's no recurring charge.
Are the results a certified benchmark?
No. This is a practical, browser-based snapshot of performance right now - not a certified hardware diagnostic, and not a comparison against a live database of other devices.
Is ScannioApp affiliated with my device manufacturer?
No. ScannioApp is an independent tool and isn't affiliated with Apple, Google, or any device or browser maker.
What if I have a problem with my purchase?
Reach out to support@scannio.app and we'll sort it out.

Results reflect your device right now and can vary with temperature, battery level and open apps.
