Overview
- Hearapy, which launched Monday on Google Play, plays a one-minute session that Samsung says can lessen nausea for up to two hours.
- The app emits a continuous 100 Hz tone at roughly 75–85 decibels to stimulate the inner ear’s balance system described in Nagoya University findings.
- Samsung promotes the Galaxy Buds 4 Pro for clean 100 Hz output, though reviewers report the app also works on other earbuds that can produce that tone.
- Early tests note the sound can feel disorienting, and the app guides users to about 85 dB, which is loud, so clear isolation and brief use are important.
- The tool offers a drug-free option for travelers who get carsick, though broader clinical validation and long-term safety outside lab settings are limited.
