Close Enough

Proximity alarm on the map — sleep on the train, get a nudge at the supermarket or gym, or ping yourself on a drive-by. Search a place (or tap the map), set the radius, write a note — it fires when GPS says you’re near.

1. Try — New point: search or mark the place + radius + note.
2. Leave the tab open; when you’re close enough, it rings and shows the note.

Web = preview in the browser (GPS + tab open). Real app on the phone (Play/App Store when published). Web = feeling, not the full alarm.
