Free accounts get Today with routines, doses, and health readings for the last three local calendar days (full detail inside that window). You can still move the date strip to older days; outside that window the app explains that full calendar history is a Family benefit—see Today and history.
Subscriber-only features still include things like shared coordination across caregivers, quick timers as a premium workflow, long-range reading trends, and generated family reports—see in-app messaging when you try those flows.
