— Interaction
Flip to begin.
There is no button. You turn Ember over to start a session; you turn it back when you leave. The object is the interface. Your hands stay free, your eyes stay closed.

Ember.
A thermal timepiece
for the sauna.
We are building a small wooden object that turns a sauna session into something you can remember. No screens. No app to open. No notifications you didn't ask for.
You flip it to begin. A slow amber glow marks the minutes. When you leave, the session is already written down.
Four ideas, and nothing more.
— Environment
Built for löyly.
Ember reads the heat and the steam the way a bather does: directly, in the room with you. Rated for real sauna conditions, not the climate of a hotel room.
· 92°C · 28% RH + löyly
— Memory
A quiet ledger of every session.
Duration, peak temperature, humidity, the rhythm of the heat — every session is written down. Not because you asked. Because you showed up, and Ember was there.

— Object
Thermo-aspen, amber, nothing else.
Shaped from thermally-modified Finnish aspen, sealed with beeswax, finished with a single amber ring. No logo. No brand mark. No notification you haven't asked for.
one session, traced.
Said plainly: what it isn't.
Ember does not talk. It does not ping you. It does not want your attention outside of the one moment that matters. If it succeeds, you will barely think about it at all.
- It is not a smart speaker with a sauna skill.
- It is not a wearable trying to survive the heat.
- It is not a sauna app in a companion dongle.
- It is not a thermostat bolted to your heater.
- It is not a subscription dressed up as an object.
It is a small piece of wood
that quietly remembers the heat.
The thermal silence.
A sauna is already one of the few rooms in your life with no screen in it. We did not want to be the thing that changed that.
So Ember is an object first and a sensor second. A piece of wood, warm to the touch, that sits on the bench beside you. You flip it, and thirty minutes later it has quietly remembered everything worth remembering.
