Overview
- Samsung rolled out the free Hearapy app this week for Android, which works only with Galaxy Buds4 Pro and is pitched to reduce travel nausea for up to two hours after a 60‑second use.
- Hearapy plays an exact 100 Hz sine wave at about 85 dB to both ears for one minute before a trip, and the effect requires no music or other sounds to interfere.
- The app sets a one‑minute timer and auto adjusts volume to roughly 85 dB, which Samsung likens to a lawnmower during short exposure.
- Use is limited to Galaxy Buds4 Pro, which Computer Bild lists at €249, with Samsung citing the buds’ larger mid‑woofer area, two‑way driver, codec support, and adaptive noise canceling to keep the tone clean.
- The approach is based on Nagoya University experiments that saw improved balance and fewer symptoms under controlled conditions, and outlets note that real‑world efficacy and long‑term hearing safety still need independent study.
