Hearapy is a free Android application designed to alleviate travel sickness using sound therapy. Specifically tailored for users of the Samsung Galaxy Buds4 Pro, the app plays a clear 100 Hz bass sine tone that stimulates the inner ear's balance organ. Users can listen to the tone for just 60 seconds before traveling, with the sound recommended to be set at a comfortable volume of around 85 dB. The app features a built-in timer and adjustable volume controls for personalized use.

Studies indicate that this sound therapy can significantly reduce travel sickness symptoms for up to two hours, offering a medication-free alternative. The Galaxy Buds4 Pro enhance the experience with high-quality sound reproduction, featuring a dual amplifier and 2-way speakers that deliver rich bass tones. This combination aims to create a smoother and more enjoyable travel experience.
