Ratings and reviews

my favorite light set up . Plus it will pull people over be careful when using this app will be very loud. Every ki d can cause people to get very upset and actually have the lock hold on you so to don't use this app unless you prepared.

LOVE the lights and sound together, work's great when they're blocking the aisle and when you say "excuse me" and they look up looking for dead birds.

Awesome to use for pranks and as a strobe light. Nice and simple app that's free to enjoy...
