Screen Flash Mode in Sleep Frustrating produces rapid, colorful flashes on a Wear OS watch display. It is one of three independently controlled modes intended to create a noticeable alertness stimulus while studying, reading or working late.

Google Play does not describe fatigue measurement, sleep-condition treatment or medical functionality. Screen Flash Mode should not replace adequate sleep.

How do I select Screen Flash Mode?

The official Google Play screenshots show a separate Screen Flash toggle in the app. Select it before using the Start Frustrating control. Because the three modes are independent, Screen Flash Mode can be selected by itself or together with Haptic Mode and Sound Mode.

What does the screen look like while the mode runs?

The listing describes rapid, colorful flashes. Current official screenshots show the watch display changing to bright colors while the active-mode summary and Stop Frustrating control remain visible.

For the separate sound-free setup topic, read Can I Use Sleep Frustrating Without Sound on Wear OS?.

What are the important limits?

Rapid colorful flashes are intentionally visually noticeable. If flashing is uncomfortable or unsuitable for you, do not enable Screen Flash Mode; the independent controls let you leave it off and use another listed mode instead.

Do not enable Screen Flash Mode if you are sensitive to flashing lights or have been advised to avoid them. Stop immediately if you feel unwell.

The app is not a safe workaround for severe drowsiness. Do not rely on flashing, vibration or sound to continue driving, operating equipment or performing safety-critical work. Stop and rest safely.

What does Google Play say about the app's data safety?

The current Google Play data-safety section reports that Sleep Frustrating collects no data and shares no data with third parties. This is the developer's current store declaration and may change in a later version.
