Zero Day

One day can be a fresh start. Zero Day helps you keep a personal record of your smoke-free journey, notice small milestones and make room to breathe when a craving arrives. YOUR PROGRESS, AT A GLANCE Follow time since your quit date, estimated money saved and cigarettes avoided. Set a goal that feels possible, from a short first sprint to a longer challenge, and celebrate milestones with illustrated badges. A LITTLE SPACE WHEN YOU NEED IT Open Craving SOS from Home for a three-minute guided breathing session. Record intensity, triggers and a note to yourself, then explore patterns by weekday and time of day. KEEP AN HONEST RECORD A lapse does not erase earlier journal entries. Restart a challenge or, when an optional rewarded video is available, keep challenge time while recording the lapse. Health timing follows your last recorded cigarette. SMALL SAVINGS, PERSONAL REWARDS Use your own pack price and smoking profile for estimates. Keep a wishlist of things you would like to put those savings towards. Add compact or dashboard widgets, choose a light or dark theme, and use English or Korean. LOCAL FIRST Core tracking works offline without an account. Export and restore a JSON backup through Android’s document picker. Choose whether to enable progress reminders. The app contains banner advertising and optional rewarded videos; these require a connection and the applicable privacy choices. HEALTH REFERENCES The recovery timeline is general educational information, not a measurement of your body, medical advice or a promise of recovery. Money, cigarette and time-reclaimed figures are estimates based on your entries; time reclaimed is not a personal lifespan prediction. Ask a qualified healthcare professional about your health or treatment.
