NO Calendar Create yours — free

A smoke-free counter right where you reach for your phone

Cravings often hit the moment you pick up your phone. That is exactly where NO Calendar shows how many days you have been smoke-free.

Next to the counter you see what has already improved — taste and smell, breathing, heart rate — and the money that stayed in your pocket.

How it works

  1. Pick what you are quitting and the day you started.
  2. Choose your phone model, one of 6 calendar views and 25 themes.
  3. Add a tiny automation (Shortcuts on iPhone, MacroDroid on Android) — your lock screen refreshes itself every morning.
