Choose a trip scenario, play a 100Hz tone, and follow simple guidance before cars, flights, boats, or VR.
Not Dizzy is a simple motion-sickness prep app designed for use before car rides, flights, boats, and other trips.
It plays a 100Hz tone based on published research and keeps the experience lightweight: open the app, choose a preset, and start listening.
Why people use it:
- 1-tap presets for common travel scenarios
- 100Hz science-based default
- Custom duration and frequency controls
- Accessibility support and multiple languages
- Local-only data storage
Best used before symptoms begin. Headphones or balanced left/right volume are recommended.
Not Dizzy is not a medical device and does not replace medical advice.
