MotionEaseTune: Motion Sickness Prevention App

MotionEaseTune is a health and fitness app by BHznJNs that aims to prevent motion sickness by playing a 100Hz tone. The idea is simple: before you start feeling queasy, you listen to a pure 100Hz sound for about one minute. According to the developer, this brief exposure to a 100Hz tone at daily sound pressure levels may help improve motion sickness. The app is designed to be used proactively, meaning you open it and listen before symptoms begin, rather than trying to stop sickness once it has already started.

The app is meant to be a straightforward tool for anyone who deals with motion sickness during travel, whether in a car, on a boat, or in other moving environments. It is not a complex fitness tracker or a medical device; it is a focused utility that plays a specific frequency to potentially reduce discomfort. Because it relies on sound, it is essential that you use headphones or ensure the volume is balanced equally in both ears, as the developer notes that both ears should receive the same volume level.

MotionEaseTune is a free, open-source application released under the GPL-3.0 license. The current version is 1.1.3, and it was released on May 29, 2025. The app is lightweight, taking up only 14 MB of storage, and it runs on Android devices with version 5.0 or higher. It is ideal for beginners because there is no complicated setup—you simply download, open, and listen. This makes it a convenient option for travelers who want a quick, non-invasive way to try addressing motion sickness without needing to take medication or use specialized equipment.

By focusing on a single 100Hz tone and a one-minute listening session, it removes all complexity and lets you try a sound-based preventive method in seconds. While results may vary, its low cost, tiny footprint, and easy installation make it worth trying for anyone prone to motion sickness.
