Samsung has quietly introduced a new way to fight motion sickness—without pills, patches, or wristbands. The company has released a free Android app called Hearapy, now available on the Google Play Store, designed to help reduce nausea and dizziness some people feel while traveling by car, bus, train, boat, or plane.
Hearapy takes an unusual approach: instead of masking symptoms, it aims to support your balance system directly using sound. The app plays a low-frequency 100Hz bass sine tone at a specific loudness. Samsung says this tone helps stimulate the vestibular system, which plays a major role in balance and motion perception. By activating that system before you start moving, Hearapy is intended to make motion feel less disruptive—potentially lowering the chance you’ll feel sick during the trip.
Although the app highlights compatibility with the Galaxy Buds 4 Pro, it isn’t limited to Samsung earbuds. Hearapy can work with other headphones as well, which is a big deal for anyone who wants to try the feature without buying a new pair of earbuds. For best results, a snug, closed-ear fit is recommended, since a secure seal can help ensure the tone plays consistently and isn’t drowned out by outside noise.
Using the app is straightforward. You listen to the 100Hz tone for about 60 seconds before traveling, and Samsung allows users to adjust the session length from 40 to 120 seconds depending on preference. After that short pre-trip session, Samsung claims the effect can last up to two hours. If your journey is longer—or if symptoms return—you can repeat the process whenever needed.
Samsung points to research from Nagoya University in Japan as the foundation for the app. In experiments focused on vestibular stimulation, researchers explored which audio tone best supported balance improvement. According to Samsung’s summary, the sweet spot was a 100Hz tone played at roughly 80 to 85 dB for one minute. There’s an important catch, though: the technique works best when the sine wave isn’t competing with music or other sounds. In other words, Hearapy isn’t meant to be played under a playlist—it needs those few moments of uninterrupted tone to do its job.
For travelers who frequently deal with motion sickness—especially those who want a drug-free option—Hearapy could be worth trying. With a quick setup, broad headphone compatibility, and a short pre-travel routine, it positions itself as a simple tool to keep in your travel kit the next time the road (or air) gets rough.
