Why DAU misleads subscription apps
Daily Active Users is a cheap heartbeat. For subscriptions it is often a quarrel with finance dressed up as App Analytics.
An audio company we later sat in the Atelier put DAU on the all-hands slide for eighteen months. Push copy got sharper. Opens rose. Completed listens did not. Finance, who live on renewals, were told the product was “more loved”. The stream showed more lock-screen accidents.
Activity is not tenure
A subscriber can be silent for twelve days and still be a good customer if the product is a weekend companion. DAU punishes that pattern. It also rewards a settings screen that nags. If your qualifying event is app_opened, you have chosen the metric that is easiest to move with chrome, not with work.
Prefer a returning-to-value cohort: second completed episode in seven days; second paid week with a captured payment, not a grace period. Write the window in English so a new PM cannot “tidy” it into calendar weeks that start on Monday in UTC while your users live in Glasgow.
When DAU is still allowed
Operational on-call, crash clustering, and “did the release brick the login” — those rooms may need a pulse. Put DAU there. Do not let it commute to the strategy deck. The Retention Atelier exists because teams keep smuggling the pulse into the strategy.
