About BOOM?

How many times have we all flooded the Facebook group with "DID YOU HEAR THAT LOUD BOOM?!?!" at 8:07 a.m. on a random Tuesday?

BOOM? turns that chaos into a fast, fun, useful live map. One tap to report. Real-time map shows who else heard it. Crowd-voted explanations so you actually know what's going on.

How it works

1. Hear a boom (or feel a rumble)
2. Tap the big red button
3. Your report hits the live map instantly
4. See if your neighbors heard it too

• Thunder — it's the Midwest, it happens

• Mystery — sometimes nobody knows
