LastGlassUnderstanding your record
Sober days and showing-up streaks measure different things
A day without alcohol and a day you returned to your plan are both worth recording. LastGlass keeps those measures separate so an honest check-in never has to pretend a drinking day was alcohol-free.

The distinction: alcohol-free counts describe the drinking record you entered. The showing-up streak rewards returning to the app: a check-in, promise, reflection or support activity can count even on a drinking day. A freeze belongs to that activity streak.
Three numbers you might see
- A current alcohol-free run counts the uninterrupted dates since the start of that run, based on the drinking days recorded.
- Total clear days counts dates in your journey without a recorded drinking day, including days before a later interruption.
- A showing-up streak counts participation in your plan. Recording a difficult day honestly still counts as showing up.
The live time display is another view of elapsed time. A clock, an inclusive calendar-day count and a total across several runs need not show the same number. Their labels matter.
A worked example
Suppose your start date is Monday. You record Monday and Tuesday as alcohol-free, Wednesday as a drinking day, and Thursday as alcohol-free. You also check in each day.
| Measure on Thursday | What the record contains |
|---|---|
| Current clear run | 1 day: Thursday |
| Total clear days | 3 days: Monday, Tuesday and Thursday |
| Showing-up streak | 4 days of returning to the plan |
Wednesday remains a drinking day. Neither a freeze nor an activity streak changes that entry. You can see the work you did around it without rewriting what happened.
What happens when you miss a day
The showing-up system can repair a single eligible missed activity day when you return the next day. Earned freezes can also protect that activity streak. The app’s rules determine whether a gap is eligible; a series of missed days does not receive unlimited repair.
A missing check-in is not proof of abstinence. The clear-day calculation uses your start date and recorded drinking days, so dates without a drinking entry can be counted. Log honestly, including past drinking days, if you want the totals to describe what happened.
Midnight, late evenings and day one
LastGlass counts calendar dates inclusively: the start date is day one. If you started yesterday and there is no drinking day in between, today is day two. That is different from waiting for two complete 24-hour periods.
The app also lets you choose when your day ends, between midnight and 6 a.m. With a 4 a.m. boundary, a 1:30 a.m. check-in can belong to the previous day. This website’s sobriety calculator uses local calendar midnight and has no access to those app settings or entries.
Milestones are fixed day counts
LastGlass marks days 1, 2, 3, 5, 7, 10, 14, 21, 30, 60, 90, 100, 180 and 365, then multiples of 365. Month and year labels are motivational shorthand. Thirty days is not every calendar month; 365 days can differ from an anniversary across a leap year.
If a number looks wrong, first check your start date, drinking entries, selected goal and day boundary. Contact support if it still does not match, without sending private journal text you do not want to share.
Frequently asked questions
Does a streak freeze make a drinking day alcohol-free?
No. Freezes protect the separate showing-up streak when an activity day is missed. They do not remove alcohol from a check-in or turn a drinking day into a clear day.
Does the start date count as day one?
Yes. The calendar-day count includes the start date and today. That differs from a timer measuring completed 24-hour periods. This website’s calculator assumes no intervening drinking days and uses the browser’s local midnight boundary.
Does missing a check-in prove I did not drink?
No. LastGlass’s clear-day calculation counts dates without a recorded drinking day from your selected start date. It is based on your record, not independent verification. Keep check-ins accurate and distinguish an estimate from confirmed logged days.
