Problem statement.
Most people who set a bedtime on their iPhone still blow right past it. The reminder meant to stop them is the easiest thing on the screen to ignore: same time, same shape, every night, losing to apps engineered to keep you watching.
How do I use Apple's position (owning the phone, the Watch, and sleep data) to make bedtime something people actually follow, not by reminding harder, but by shaping the hour before bed without nagging or guilt that gets the feature switched off?
