Hearapy for iPhone?
Samsung's Hearapy app plays a 100 Hz sound for travel comfort — but it's only available on Android. Stillwave brings the same idea to iPhone. Both apps work with any earbuds, but noise-cancelling earbuds are recommended.

When Samsung announced Hearapy in April 2026, it put a spotlight on a simple idea: a 100 Hz sound as a travel-comfort companion. We thought iPhone users shouldn't be left out.
But Samsung made Hearapy exclusive to Android. If you're an iPhone user, you were left out.
Stillwave fixes that. We built an app around the same simple idea — a fixed 100 Hz pure tone — that works on any iPhone with any earbuds.
We also added features Hearapy doesn't have: a 2-hour session countdown timer and smart earphone detection that guides you to use noise-cancelling earbuds in a quiet environment for the clearest sound.
No. Samsung's Hearapy is only available on Android. Stillwave is an independent alternative that brings the same 100 Hz sound concept to iPhone users. Both work with any earbuds — noise-cancelling recommended.
No. Stillwave is an independent app by Nullpointer Studio. It is not affiliated with, endorsed by, or connected to Samsung in any way. Both apps independently use a simple 100 Hz pure tone.
Both apps are based on the same simple idea: playing a fixed 100 Hz pure tone through earbuds. Stillwave is an independent implementation.
Both Stillwave and Hearapy work with any earbuds. However, noise-cancelling earbuds like AirPods Pro are strongly recommended — Active Noise Cancellation blocks ambient noise, letting the 100 Hz tone come through most clearly. Use in a quiet environment for best results.
Samsung bundles Hearapy as a value-add for their Galaxy ecosystem. Stillwave is an independent app with no corporate subsidy. The $0.99 price is a one-time purchase with no subscription, no ads, and no data collection — a fair trade for a tool you'll use on every trip.
Both apps play the same fixed 100 Hz pure tone at 75-85 dB through earbuds. For the clearest sound, use noise-cancelling earbuds in a quiet environment. Stillwave adds a 2-hour session timer that Hearapy doesn't have.
Same idea. Works with any earbuds. Built for iPhone.
