Ratings and Reviews


Needs more customization options

Great app, but it needs more customization options like choosing thunder and lightning frequency, and maybe even a two buttons, one to trigger lightning and the other to trigger thunder, how loud the thunder is will depend on how long after the lightning flash you push the button.
