Stay on the calendar, or shift after late logs

Why did my next dose move?

Every routine follows one of two rules: Stay on the calendar keeps every dose on its planned day; Shift after late logs re-anchors the next doses to the day of your latest logged dose.

AvailabilityFree · Assumes a routine on an interval schedule (every N days)

Every routine follows one of two rules. Stay on the calendar keeps every dose on its planned day whatever you log. Shift after late logs re-anchors the next doses to the day of your latest logged dose. The setting is If I log late on the routine form (under More options on a new routine; already open when you edit one); new routines start on Stay on the calendar.

Where to start

The routine form › If I log late.

What each rule counts from

On Stay on the calendar the anchor is the routine’s start day. On Shift after late logs the anchor is the day of the latest dose you logged as done or late — a skipped dose never re-anchors, and neither does moving a dose.

Example A — Stay on the calendar

Fictional exampleThe names and values below are made up to show how the parts relate; they are not a suggestion.

Routine: Every 3 days from Mon 1 Sep 2025
Planned days: Mon 1, Thu 4, Sun 7, Wed 10 Sep 2025
Log any of them late: The rest stay put.

Example B — Shift after late logs

Fictional exampleThe names and values below are made up to show how the parts relate; they are not a suggestion.

Routine: Every other day from Mon 1 Sep 2025
The Wed 3 Sep dose: Recorded with Taken at Thu 4 Sep
Stay on the calendar: Fri 5, Sun 7, Tue 9 Sep
Shift after late logs: Sat 6, Mon 8, Wed 10 Sep — the next doses count from the Taken-at day, and that day itself is not repeated.

This is the interval-schedule behaviour (every N days, every other day, every 3 days); weekly-on-days and times-per-week routines are not claimed to shift identically until verified.

Fictional example: the same late log leaves a Stay-on-the-calendar routine unchanged and shifts a Shift-after-late-logs routine to count from Thursday.

What changes

Changing the setting replaces only pending doses that no longer match the plan — those still Upcoming or Due; doses you have acted on, and doses already Late or Missed, stay as they are. On Shift after late logs the anchor is the Taken at date of your latest dose logged as done or late — the time you record, not the moment you enter it.

Where: The routine’s next doses on Today and in Calendar

If it looks different

The setting is hidden?: It sits under More options, collapsed on a new routine.
An early log also moved the schedule?: On Shift after late logs the rule uses your latest logged dose, early or late.
Past weeks don’t redraw after a change?: Adherence for those weeks reflects the plan at the time.
Skipped or moved a dose?: Skip and Move never shift the routine; only a dose logged as done or late re-anchors it.
