Why a date alone isn’t enough
Your phone’s calendar can tell you it’s Sam’s birthday. It can’t tell you Sam just started a new job, or that you promised to send the photos from the wedding. That context is what turns “HBD!” into a message that lands. BlackBook keeps the reminder and the context in the same place.
