Separate experiments

Run these after recording baseline results. No media or metadata is uploaded or saved. Results disappear on reload.

File readability over time

Selection may consume Safari storage. Use a small controlled sample. Each selection replaces the previous one.

Select a test photo or video

No file selected.

No contents read. A read happens only when you tap the button.

Repeat the read after waiting or switching apps. Success proves only that this slice was readable at that moment, not that the full file or a restarted page will work.

☕ Keep Screen Awake

Checking support…

Keep this page open and the device plugged in. This does not enable background uploads. When enabled, the experiment requests a new lock on returning to the visible page.
