Breathing pacer for sleep

A breathing app you feel, not just hear

Pianissimo is a paced breathing app for iPhone. You lie down, rest your phone on your breastbone and put on headphones. A gentle vibration swells and fades at 5 or 6 breaths a minute, with a deep, warm tone and one of 11 calm sounds. Sessions last 5, 10 or 15 minutes. Your first session is free.

How does Pianissimo work?

  1. Lie down. In bed, on the sofa, on the floor.
  2. Phone on your breastbone, headphones on. The vibration marks each breath; the tone and the sound bed play in your ears.
  3. Breathe with the swell. In as it grows, out as it fades. Close your eyes.
  4. Done. You see how many minutes you breathed and at what pace.

Why your phone, and not another gadget?

Because you already own it. There is no device to buy, nothing to charge or pair, no account to create. Pianissimo works offline, on the phone that is already on your bedside table.

How much does it cost?

Your first session is free. Then you choose a one-time purchase (“One purchase, yours forever”) or a yearly plan. The price for your country is shown in the App Store.

FAQ

Do I need headphones?

Yes, they are recommended: the tone and the sound bed are designed to be heard close, while the vibration is felt through the phone.

Is it a subscription?

Not if you choose the one-time purchase: no subscription, no renewal. A yearly plan is also available.

Does Pianissimo collect my data?

The App Store privacy label is “Data Not Collected”. No account is needed.

Is it available on Android?

Not yet. Pianissimo is available for iPhone; an Android version is in development.

Is Pianissimo a medical device?

No. It paces your breathing with sound and vibration. Ask your doctor first if you have a heart, lung or breathing condition.

Before you start

A relaxation session, not a medical device. A phone contains magnets and radios: Apple advises keeping it away from implanted medical devices, so do not rest it on your chest if you have a pacemaker or defibrillator. If you are pregnant or have a heart or lung condition, ask your doctor first.
