More than a counter

You look after a dragon that has smoked for as long as you have.

At the start it is small, grey and coughing. Every day you do not smoke, it gets healthier: its colour comes back, it stops coughing, and it learns to fly. The app also shows real health milestones from the CDC and the NHS.

The stosmok dragon at the Blaze stage, healthy and orange

Your dragon

Six stages, based on your smoke-free time

Your dragon changes at fixed points in your smoke-free time. More changes happen in the first weeks, because that is when not smoking is hardest. Each stage has three steps, so there is always a new change within a few days.

Day 0

Ashling

Small and grey. Cannot fly. Coughs up soot. Its eyes look tired.

Day 3

Ember

Some warm colour comes back to its belly. It stops coughing.

Day 14

Cinder

More colour. Taller, with half-grown wings. Reacts when you tap it.

Day 30

Blaze

Full wings and a flame on its tail. Breathes light instead of smoke.

Day 90

Skyborn

Full colour. Flies well. Breathes light.

Day 365

Astral

The last stage. Glowing light around it, star patterns on its body, and it breathes starlight.

What's inside

Tools that help you quit

No tricks and no guilt. Only tools that help, in a friendly app.

Craving SOS

One button you can reach from every screen. Do a guided 4-7-8 breathing exercise with your dragon, play a 60-second game, read your own reasons for quitting, or start a 5-minute walk timer.

A sourced recovery timeline

Fifteen milestones, from 20 minutes to 20 years, taken from CDC and NHS guidance on quitting smoking. Every figure is marked as an estimate, and the sources are shown in the app.

Badges and challenges

Animated badges, weekly challenges, and levels that unlock free cosmetic rewards. You never need any of them to use the tools that help you quit.

Insights from your own cravings

The app looks at the cravings you log, on your phone, and shows your main triggers and your hardest times of day. The longer you use it, the better your reminders fit you.

Works offline, private by default

The app works fully in airplane mode. Your health data is calculated and stored on your phone and never sent anywhere. The internet is used only for purchases and optional crash reports.

Our promise

Pay once, keep it forever

Because you pay only once, the app has no reason to keep you scrolling or to push more purchases. Help during a craving is never sold.

No ads, ever

The app makes money from one payment only. It has no reason to show you ads.

No account

There is no sign-up, no login, and no user database. The app never asks for your name or your email.

No subscription

Free to install and free for your first three days. After that, one payment unlocks everything forever. The SOS craving tools are always free. The only extra purchases are dragon skins and colour themes.

stosmok is not a medical device and does not provide medical advice. Health timings come from CDC and NHS guidance on quitting smoking and are shown as estimates. The life-expectancy figure used in the app (11 minutes regained per cigarette not smoked) comes from Shaw, Mitchell and Dorling, BMJ 2000. If you want medical support to quit, speak to a doctor or a smoking cessation service.
