Find your tone.

It takes a few minutes. With headphones on, pick the tone closest to the one you hear, check the octave and match the loudness.

Tone matching is for ringing that sounds like a tone. If yours is more of a hiss or a hum, skip it and pick a calming sound you like.

This is your sound: pink noise with a quiet gap at your tone. Listen for a minute before you decide.
Which tone is closest? Slide along the water to hear each tone.

Hear the gap.

Your sound is soft pink noise with a gentle gap half an octave wide, right at your tone. Press play, then move the gap along the line.

The gap sits at a high ring

Plays quietly, only when you press. Headphones help.

Night mix: your sound, rain and ocean, each with its own level. Playing, stops in 45 min.
Sleep mode: 45 min left in dim amber. The night mix fades out at the end of the timer.

Fall asleep with it on.

Mix your sound with rain or the ocean and set a timer. The mix fades out on its own. Sleep mode turns the screen a dim amber, so checking the time doesn't light up the room.

Your bed is for sleep.

A wind-down hour.

Questions

Is Halcyo a treatment for tinnitus?

No. Halcyo is a relaxation and self-help tool, not a medical device. It does not diagnose, treat, cure or prevent tinnitus or any other medical condition, and it does not replace your doctor or audiologist. If your tinnitus is new, one-sided or pulsing, or came with hearing loss or dizziness, please see a doctor.

What is the sound with a gap?

Everyday sound, such as soft white, pink or brown noise, with a small gap around the pitch you hear. You choose how loud it is.

What if my ringing isn't a single tone?

Skip tone matching. You still get calming sound and night mixes, and the lessons and check-ins work the same way.

Do I need headphones?

For matching your tone, yes. For listening, a speaker in the room works well, especially at night.

Is the volume safe for my ears?

Tones and sounds stay under a fixed level cap. Halcyo can remind you to turn it down after an hour at a high level, and pause when your headphones disconnect.

What happens to my data?

Your answers, check-ins and tone stay on your phone, and there's no account. Read the privacy policy and the consumer health data privacy policy for the details.

How do I cancel?

In your App Store or Google Play subscription settings, anytime. We remind you two days before a free trial ends.
