Two ways to count
| Method | How | Suits |
|---|---|---|
| Last-cigarette time | One day per 24 hours since the last cigarette | People who want exact elapsed time |
| Calendar days | Tick each day you didn’t smoke | People who close the day with a log |
Say your last cigarette was Monday at 11 pm. By the clock, day two ends Wednesday at 11 pm. By the calendar, Tuesday was the first full day without smoking, so Tuesday is day one.
Tricky cases
- Smoked during the day you planned to quit — by calendar rules, that day doesn’t count. Tomorrow is day one.
- Smoked at 1 am on a night out — the date is tomorrow, but it feels like last night. Decide in advance whether a “day” ends at midnight or when you go to bed. See after drinks.
- Installed the app a few days late — you can go back and log those days.
How the app counts

Calendar days, one cut per day
Quit Smoking Tracker counts calendar days. A day you cut the cigarette is a smoke-free day, and consecutive days form your streak. If you haven’t cut today yet but yesterday is logged, your streak holds; cutting today adds one.
Fill in past days
Tap the calendar icon in the date field, choose an earlier date and cut the cigarette to save that day too. Any gap breaks the streak at that point.

Check the History calendar
Scan the History calendar for missing ticks and fill any gaps.
The app’s screenshots show sample amounts in Korean won (4,500 per pack is the app default), and the Settings sheet title is shown in Korean in the current English version. Enter your own local pack price; the calculation works the same in any currency.
FAQ
I forgot to log yesterday. Did my streak break?
Change the date to yesterday on the Record tab and cut; the streak reconnects.
I want a live hours-and-minutes counter.
The current public version counts in days. Write your last cigarette time in the day-one memo if you want it on record.
