Use Case
A 60-second 100 Hz sound session — same vestibular approach as for car travel.
Same 100 Hz sound session — try it for your situationSeasickness is caused by the same vestibular mismatch as car sickness — your inner ear detects the boat's rocking motion while your eyes may see a stable cabin interior.
Stillwave plays a fixed 100 Hz pure tone through earbuds. The tone reaches the inner ear's balance structures — the same otoconia involved in car sickness. The app has not been specifically tested for boat motion, but the underlying inner ear anatomy is the same.
Stillwave is a lifestyle/wellness tool, not a medical device. We recommend it as a complementary approach alongside other seasickness precautions.

Not specifically. Stillwave has not been tested for boat motion. The inner ear structures involved in seasickness are the same as in car sickness. We recommend trying it on a short boat trip first.
For mild seasickness, it may help. For severe seasickness or multi-day cruises, consider combining Stillwave with other well-established options like scopolamine patches (prescription) or staying on deck.
Before boarding is best. Playing it before motion starts — rather than after symptoms begin — gives you time to settle in.
60 seconds of sound, up to 2 hours per session.
