About the author

I smoked for 26 years and I haven't smoked since 2023. I made Quit21 to help other people quit.

Quit21 is the app these pages come from. Each morning it opens a page for that day of quitting, and the pages in this section are those same texts, word for word. I wrote them.

Every text ends with the sources it relies on, so you can open them and check any claim yourself. I am not a doctor, and the texts have not been through a medical review. Quit21 is not a medical device. For medication or nicotine replacement, talk to a doctor or a stop-smoking service.

There is no account. What you write in the app stays on your phone.

If you find a mistake in a text, write to apps@lymar.dev.
