Open this page in Safari on an iPhone. The file goes straight into Shortcuts.
What happens
Each time they open one of the chosen apps, the whole phone flips between light and dark mode. Open, flip. Open, flip.
Setup
- Open the download on their phone (or AirDrop it over) and tap Add Shortcut.
- Long-press it in Shortcuts → All Shortcuts → Rename and call it Display Sync, so it doesn’t give itself away.
- Shortcuts → Automation → + → App, pick 3–4 apps they use and choose Is Opened, select Run Immediately, tap Next and choose the shortcut.
- Run it once now and tap Always Allow on every prompt, or the prank fizzles on a permission dialog later.
Undo
Open Shortcuts → Automation, swipe left on the automation and tap Delete. Then delete the shortcut. Set Settings → Display & Brightness back to their usual appearance.
