The ads are beyond intrusive. I half woke around 3am & wanted to quickly turn on a sound to help lull me back to sleep before I was so fully awake that my brain engaged & sleep would be impossible. But instead, this app popped up TWO super annoying ads that could not be closed, bouncing back & forth between the product website & the add for 15-20 clicks each ad before finally letting me close it & start a sound, by which time I was fully awake & fully annoyed. Ridiculous! I've uninstalled.
