What to check before buying a sleep device
- Total cost over 2 years, including any app subscription that starts after year 1.
- Charging and pairing: one more device on the bedside table.
- Hands: some devices must be held during the session.
- Return policy, in case the format does not suit you.
- Claims: be wary of devices that promise medical effects without published studies of that device.
Can a phone replace a breathing device?
For paced breathing, often yes. With Pianissimo, you lie down and rest your phone on your breastbone: the phone’s vibration swells and fades with each breath, and a deep, warm tone plays in your headphones. Your hands rest; your eyes stay closed.
No device to buy. Nothing to charge. Try one full session free, on the phone you already have.
When is a device the better choice?
- You do not want a phone in your bedroom at all.
- You want something a child or an older relative can use without a smartphone.
- You prefer a light or a physical object to a vibration.
FAQ
Does a breathing app need the internet?
Pianissimo works offline and needs no account.
Is the vibration strong enough through a phone?
You choose Gentle, Medium or Strong, and can test it before starting.
Is a sleep aid device a medical device?
Most are sold as wellness products, not medical devices. Check the label, and see a doctor about ongoing sleep problems.

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.
