Samsung has introduced a new Android application called Hearapy, offering it free of charge via the Google Play Store. The company says the app is designed to ease motion sickness symptoms using carefully tuned sound rather than medication or physical remedies.

The concept behind the app is relatively simple. Users listen to a low-frequency 100Hz sine wave through connected headphones for a short period. This sound is intended to activate the vestibular system, which plays a key role in balance and spatial awareness within the inner ear. By stimulating this system, Samsung suggests the app may help counter feelings such as nausea and dizziness.

The default listening time is set at 60 seconds, though users can adjust it anywhere between 40 and 120 seconds depending on preference. According to Samsung, a one-minute session could provide relief lasting up to two hours, and the process can be repeated whenever symptoms return.

The idea builds on findings from research conducted at Nagoya University in Japan, published last year. That study indicated that certain sound frequencies could reduce discomfort and instability experienced by individuals reading while travelling in a moving vehicle. Samsung appears to have adapted those findings into a consumer-friendly tool.

However, the company acknowledges that results are not guaranteed and may differ from person to person. Performance can also depend on the headphones being used. While Hearapy is compatible with most earbuds and headsets, Samsung advises using devices capable of delivering sound at around 80 to 85-decibel levels to achieve the intended effect. It specifically highlights its Galaxy Buds 4 Pro as a suitable option, although the app is not limited to its own hardware.
