“Why not have an agent that looks at your calendar and wakes you up an hour before your first appointment that day?”

ALREADY EXISTS, YOU'RE LATE

“Congratulations, you just reinvented the alarm clock with extra steps and an API bill.”

An agent that reads your calendar's first event each day and sets a wake-up alarm exactly one hour before it.

This is so solved it hurts. Smart alarm functionality is baked into Google Assistant, Apple Shortcuts, and Samsung's Bixby Routines natively. The graveyard of 'smart alarm' apps on the App Store is deeper than your sleep schedule. The only people who don't have this already are the same people who still set 7 individual alarms.

Pros & Cons

What's going for it

Genuinely useful daily utility — calendar-aware waking actually reduces morning panic
Could extend to account for commute time via Google Maps API, which most existing solutions don't do well
Niche premium angle: corporate users who live and die by their Outlook calendars and hate consumer apps
Low infrastructure costs — this is basically a cron job with calendar read access

What's against it

Apple Shortcuts can replicate the MVP in 15 minutes for free — your entire moat is zero
Consumer alarm app market is brutally saturated with 200+ apps fighting for 2-star reviews
Google and Apple will ship this as a native feature the moment it trends on Product Hunt
Calendar OAuth scopes are a nightmare — users freak out giving any app calendar access
Retention is near-zero — once it works, users never open the app again
