Overview
- Hearapy is now available on Google Play as a phone app that plays a steady 100 Hz sine wave to counter motion sickness.
- The session runs for 60 seconds and Samsung claims the effect can last for up to two hours.
- Samsung is promoting the app with the new Galaxy Buds 4 Pro, which it markets as delivering clean, powerful 100 Hz output.
- SamMobile and 9to5Google report the app also works with many non‑Samsung earbuds that can reproduce 100 Hz clearly.
- The outlets did not measure motion‑sickness relief, with Samsung’s claim grounded in Nagoya University research on 100 Hz tones improving balance.
