Good quality app

Ive got a lot of background noise at work. This should be great for drowning that out during coding sessions. One thing I noticed is that there are 2 thunder buttons but one of them just sounds like rain. Perhaps a mislabel? Works great though. Noticed there are similar apps from the same maker with purpose variations. Would be good to have a combined version with different modes (meditation, sleep, etc...)
