HanabiSpot: Meetup Pin

Fireworks festivals and summer crowds make it terribly easy to lose sight
of your kids or friends. HanabiSpot fixes that with one job done well:
drop a meetup pin exactly where you're standing, add a photo and a short
note ("in front of the red-lantern stall"), and everyone can find their
way back.
When you get separated, HanabiSpot points a big arrow toward the pin and
shows the distance, so you can walk straight to it even in a dense crowd.
A Live Activity keeps the direction and distance on your Lock Screen,
so you barely need to open the app. Share the spot as a QR code and your
group can open it in their own Maps app — no need to install anything.
Built for fireworks nights, summer festivals, theme parks, and any place
a family or group might drift apart.
