Most people keep their ringer on all night "just in case" and get woken up by calls that could've waited. Sleep Mode fixes that — set your sleep hours, and callers automatically get a text saying you're asleep. If they call again, it rings through — treated as urgent. Built from scratch with AI (Claude) as a coding partner, zero prior Android experience.
