For years you may have heard the rumor that you can attract a firefly with a penlight and some patience. Well that turns out to be true… but you need to be willing to sit in the dark long enough to learn the exact flash patterns of your local firefly species.

Then you can select from six species to emulate and five flash color wavelengths. With your settings dialed in all you need to do is wait for a firefly to flash and then tap your screen.
