Needs better thunder sounds

The concept and ability to configure the storms is absolutely astoundingly done. The only issue is solely with the thunder. Almost all of the thunder sounds are of the sharp crack sound, no rolling thunder. This apps desperately needs the calmer and enjoyable rolling thunder. Most of the thunder just sounds like a gun going off. If this gets resolved, then this would be the top storm app. If it doesn't, there are a few others that are better and more enjoyable to listen to.


I'm a crazy storm lover and the rain and distant crackling always soothes me to a calm state. This app if perfect because you can even customize it to create your own storm. So say you're more of a rain person rather than thunder, just customize it to add more rain/less thunder! It's amazing! I recommend this app to anyone who needs noise to fall asleep!

This is a great app.

This is very good white noise app. It is fairly small in size as far for what it does. Some sound effects on other apps don't sound as good and it
Is better than some that just loop the sound and you can tell. Thanks guys good job.
