Samsung has launched a free app called Hearapy that aims to reduce motion sickness using sound instead of medication.
The app plays a 100Hz tone (around 75–85 dB) through headphones, which helps stimulate the inner ear’s balance system. This approach is based on research from Nagoya University, showing it can reduce nausea and improve balance for up to two hours.
Hearapy is simple to use – just play the tone for about a minute – and works best with Samsung earbuds, though other headphones also appear compatible.
