Car sick when you
look at your phone?

Why can reading in a car feel uncomfortable?

A common explanation is sensory conflict: your body senses the vehicle moving while your eyes focus on a relatively still screen. The CDC Yellow Book describes how these signals can disagree.

Put comfort ahead of the screen.

If looking at your phone makes you feel unwell, take a screen break. Looking toward the horizon and avoiding reading are among the behavioral approaches discussed by the CDC. They are not guaranteed to work for everyone.

What are visual motion cues?

Visual motion cues add moving references to a screen. Apple offers a built-in Vehicle Motion Cues feature on supported devices. NoMo is a separate app that gives you Dots, Lines and Frame, with settings you can change.

Compare the two options before deciding whether to download another app.

If you choose to explore NoMo.

Choose one style, start with comfortable settings and observe how you feel. NoMo also offers Picture-in-Picture and optional Comfort Audio. Stop if the experience is distracting or makes symptoms worse.

NoMo has not been presented here as a clinically proven treatment. Persistent or severe symptoms need medical advice.
