Everyone ends up in the ashes once.
The breakup. The job. The couch that ate a year.
At the edge burns the last forge.
It takes one currency: a word you'll keep.
Durgan melts your vow into a blade.
Then it's you against the shadow. 66 days. Four attacks a day.
What do you want to change in the next 66 days? Write it down. Watch what the forge does with it.
Stays in your browser. Nothing is sent anywhere.
Every boss is a shadow of a broken promise. It takes the shape of what broke you. Tap one and listen.
In the app you name your own boss. The name never leaves your phone. The boss mocks your excuse, never you.
This is one day in Molten Vow. Four habits are your four attacks. Try it.
Your hero grows with every chapter you win. Lose one, and it goes into the chronicle. Nothing is taken from you.
In the best-known study on habit formation, it took participants a median of 66 days until a new behaviour ran on its own. Some needed 18 days, some more than 250.
That's why a chapter lasts 66 days. Long enough for a habit to stick. Short enough to see the end.

A shared chapter. On October 27, 2026, exactly 66 days are left in the year – the length of one chapter in Molten Vow. Everyone who joins starts Day 1 together and plays until New Year's Eve, each with their own boss and their own four habits. Flow, who builds Molten Vow, plays the same chapter in public on TikTok, Instagram and YouTube. Free.
The beta is completely free. Later there will be a fair free version: your tracking is never locked behind a paywall. Extra bosses and deeper reflections will be premium.
Yes. Molten Vow runs as an app you install from the browser (Safari on iPhone, Chrome on Android). No app store needed during the beta.
It stays on your phone. No account, no cloud. Your boss name, your vow and your notes never leave the device. Feedback during the beta is anonymous and contains numbers only.
It's written for men who are rebuilding, in tone and in its bosses. Anyone can play.
Then a game is not enough, and that's okay. The app has a help section with crisis lines, and when your mood stays very low, the boss goes quiet. Help is below.
