Fireflies is an enjoyable app for both kids and adults alike. To get the maximum effect, I recommend you play with Fireflies in the dark. Reminiscent of childhoods past, you’ll soon be immersed in the sound of crickets chirping their nighttime serenades as you gently reach out to capture the fireflies, flickering in and out between the cattails. This is relaxing entertainment. Your kids will love it, too!
