Not Dizzy: Motion Sickness

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.
