Diskio: Disk & SSD Speed Test downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users

Stickiness (DAU / MAU)
how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
51/100
faster than 52% of Utilities apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.

About Diskio: Disk & SSD Speed Test
How fast is your storage? Measure sequential read and write speeds on your iPhone or a compatible external drive. Go beyond one number with repeat runs and a detailed report.
SEE THE WHOLE RESULT
Choose 1, 3 or 6 runs. With 3 or 6 runs, see median read and write speeds, minimum and maximum values, and the result of every run.
CHECK CONSISTENCY
Choose 6 runs to assess read and write stability separately over the last five. See whether results are stable or vary, with the criteria explained in the app.
TEST YOUR SETUP
Use your iPhone's internal storage or select a compatible, writable external drive through Files. Choose a test file from 1 to 5 GiB and a block size of 1, 2, 4, 8 or 16 MiB. The defaults are 6 runs, a 1 GiB file and a 2 MiB block.
UNDERSTAND THE MEASUREMENT
Speeds are shown in MB/s, and write timing includes final filesystem synchronization. Follow each write and read phase as the test runs.
SHARE THE DETAILS
Send a result card with the full report, test settings and, after 6 runs, the stability assessment. The interface supports light and dark appearances, larger text and Reduce Motion.
ADAPTS TO YOUR DISPLAY
On iPhone Duo, an expanded layout gives controls and results their own space. Your report stays available as the layout changes, and narrow windows use a compact view.
GET STARTED
1. Select your storage and test settings.
2. Start the test and keep Diskio open.
3. Review the report or share your results.
A test needs enough free space for a temporary file. External storage must be accessible and writable through Files. Results depend on the device, storage, connection, free space and test settings.
The stability assessment adapts numerical criteria from SNIA SSS PTS. It is not a full SNIA-compliant benchmark, a drive-health check or a sustained-performance rating. Results from version 3.0 onward may differ from older versions because the measurement method was revised.
