The Pebble · Hardware · Shipping spring 2027

Two warm stones.

A pair of palm-sized, wireless, haptic pebbles. For people who don't want their phone in it.

The app is enough for most people. For some — eyes closed, in bed, or in a clinician's office — a dedicated pair of tactile devices is a calmer primitive. We've been designing the Pebble for the last year and a half. It's close.

Design notes

Things that are not on it.

i.

No display.

A screen invites a glance, and a glance invites a notification. The Pebble has one status LED, facing inward toward the dock, and that's the entire feedback surface.

ii.

No account.

Pair once via Bluetooth; it remembers the phone. No registration, no cloud login, no email. If you lose the device, you just pair a new one.

iii.

No biometric sensors.

No heart rate, no SpO₂, no sleep tracking. We thought about it. We decided a tool for calming shouldn't also be a tool for measuring yourself.

iv.

No speaker.

Audio plays, if you want it, from your phone or earbuds. The Pebble is a haptic object; that is the whole thing it does.

v.

No logo, on the outside.

A small mark is etched under the USB-C contact, where the dock hides it. The visible surface is one continuous curve.

vi.

No sharp edges.

Machined from one piece, skinned in a silicone designed to warm to body temperature in about twenty seconds. It does not feel like a gadget.

Interaction

Three gestures.

Everything else lives in the app. The Pebble's job is to be in your hands.

Press to begin.

A single press on either pebble begins your last-used preset. A second press ends it early, with a slow fade.

Hold for ambient.

Long-press either pebble for three seconds to drop into Ambient — a continuous, very slow rhythm that doesn't end until you press again.

Tilt to sync.

Tilt one pebble toward the other. They find each other and begin an alternating set. It's a small piece of delight.

We'll write once, when they ship.
Nothing in between.

No drip campaign, no countdown. If you leave your email, you'll hear from us the week the first pair ships, and not before.

Approximately 1,400 on the list so far.
