I'm a first-time app developer from Seoul. Most alarms only tell you the
time, but the thing I actually needed to know every morning was whether
I could still make it — so this one checks the live transit/traffic
route to wherever you're headed at the moment it rings, and shows the
travel time and arrival on the lock screen.
On iOS 26 it uses AlarmKit, so it rings through Silent mode and Focus
and works with the app killed. That part was the hard bit: the system
owns the alarm UI completely, custom sounds have to be .caf in the
bundle, and dismissing your own screen doesn't stop the alarm — you
have to call stop() yourself.
What I can't do is test it outside Korea. I use Kakao's transit API here
and fall back to Google Directions elsewhere, and I have no idea how
good those results are in other cities. If you try it, I'd love to know
whether the travel time is anywhere near right for your commute.
If I have a meeting at 11:00 and I have 40 minutes of conmute, I add an alarm at 10:10 that says "Meeting 11:00". So I have 10 minuter to prepare and then the time to travel.
Is it possible to add some pad time? How optimistic/pessimistic is it to calculate the travel time?
