Works wonders for my lucid dream work
The sound that helps me most is Back Home, because many rain fall recordings inevitably end up sounding like somethings sizzling to me, and this has a nice under a roof ambience to it, and the thunder is mostly off in the distance and rumbling.
But plenty of others come to mind as nice relaxation sounds, such as Aegir and Night at Lake Alone. Great, great app.
