Today
The Stone in full, the counter, and the road to the next stone. Below: what you have saved, the cigarettes not smoked, the life you got back.
From ember to diamond
Basalt turns every smoke-free day into a volcanic stone whose inner light keeps clearing. One number, one stone, nothing else to look at. No charts, no calendar, no red.
The five Stones
Time is not read off a timeline here — it is read off the material. Every stone shares the same DNA: a dark, cracked crust with an inner light coming through the veins. What travels through the veins is what changes.
Moving up a tier has its own ceremony: the light withdraws, the stone goes dark for a few seconds, then a new light is born in a fissure and takes every vein. Five and a half seconds, once per stone. Here are all four, back to back.

All five stones are earned. None is for sale, at any price.
The app
Free, forever
Every screen carries a single number in close-up, and every number can say where it comes from: tap any measure to open its arithmetic, with your figures, your source and your margin. A number without provenance is endured first, then doubted.

Smoke-free for
14days
The material is ennobling.

The Stone in full, the counter, and the road to the next stone. Below: what you have saved, the cigarettes not smoked, the life you got back.
Twelve recovery markers, from twenty minutes to fifteen years, after the WHO and Tabac info service. Each one lights up in the colour of the stone you earned.
Guided breathing on a turning ring, and a promise kept: the craving passes in three to five minutes. Nothing to fill in while it lasts.
What you no longer burn adds up, and meets real thresholds. Never “you treated yourself” — nobody bought anything.
Slips
Declaring a cigarette takes two taps. The Stone dims, then relights on its own over twenty-four hours. The counter does not move — it simply stops claiming to measure what it no longer measures.
No red, no broken streak, no lecture. Our only sensor is what you declare: the design has to make lying pointless. Basalt does not watch you. It believes you.
Basalt+
Basalt+ does not track you better. It reads your numbers.
Nothing that helps you quit sits behind the subscription. The price is shown in the app, in your currency, before any commitment.
Your data
Basalt works without an account. What you declare — your quit date, your consumption, your cravings, your slips — is written on your device and does not leave it.
No advertising profile, no resale, no health data passed to anyone.
