FAQ

Common questions

Is this the same as Samsung's Hearapy app?

Stillwave is an independent app that brings the same 100 Hz sound concept as Samsung's Hearapy to iPhone. Hearapy is only available on Android. Both work with any earbuds.

What does it actually do?

Stillwave plays a single, fixed 100 Hz pure tone as a calm listening session. It is a lifestyle/wellness tool, not a medical device, and it makes no medical claims. Individual experiences vary.

Do I need AirPods Pro?

Any earbuds or headphones work, but AirPods Pro are strongly recommended. Their Active Noise Cancellation blocks outside noise, letting the 100 Hz tone come through clearly. If you don't have noise-cancelling earbuds, use Stillwave in the quietest environment possible.

Do I need a quiet environment?

Yes. The 100 Hz tone comes through best when it's the dominant sound reaching your ears. Ambient noise — engine rumble, chatter, music — can drown it out. Use noise-cancelling earbuds (AirPods Pro recommended) or find a quiet spot. Do not play music or other audio during the 60-second session.

Does it work in the background?

Yes. The tone continues playing when you switch to other apps or lock your phone. The 60-second session completes even if you're not looking at the screen.

Is there a subscription?

No. Stillwave is $0.99 one-time purchase. No subscription, no in-app purchases, no ads, and no data collection. You pay once and use it forever.

Is it safe for children?

The 100 Hz tone is a low-frequency sound at moderate volume. However, we recommend parental supervision and consulting a pediatrician for children with hearing sensitivities.

Ready for calmer travel?

No pills. No patches. No side effects. Just 60 seconds of sound.
