Your DAU line is a weekend story in disguise
A Monday DAU spike in a United Kingdom consumer app is often last week’s chores arriving late. People open the thing they postponed, complete a task, and leave. The chart records a crowd. The product recorded a queue.
We see the inverse on Sundays: a trough treated as churn. For a grocery app that is a calendar. For a workplace tool it may be the same calendar wearing a different shirt. Neither is a verdict on onboarding copy.
What to put on the slide instead
Compare Tuesday–Thursday with Tuesday–Thursday. Annotate bank holidays before the meeting, not during the interruption. If you must show a daily line, pair it with a weekday-indexed view so a director cannot point at Easter Monday and call it a growth story.
In Signal Cartography we ask students to bring one DAU slide they have already presented. Most of them contain a weekend they did not mention. The repair is a sentence in the caption, not a new vendor.
App Analytics is allowed to be dull on this point. Dull numbers that survive a calendar are more useful than an exciting line that forgets the country you operate in.
