This app works great for everyone in my family. If you have family members with trouble falling asleep-- like young children, this app is awesome. I let my kids play with the sounds and pictures, which the had fun with for a few nights. After a few minutes each night, Id reduce it down to one or two of the sounds, choosing the most calming ones. The train sound was popular, as was the train picture. Within a short time, the sounds they and I chose, and that picture they chose, were cues that it was time to wind down and get ready for sleeping. Soon after that, the sounds themselves would make the kids tired. It actually worked on me too, unintentionally, but that was a good thing in my case. I have been recommending this app to everyone I know. The updates have even better pictures than the original pics. Excellent work on both versions! Suggestions: offer a partner app that has wake up sounds Or add an alarm function on this app so that it turns ON at a designated time. I didnt look hard, but I saw only a function for it to turn OFF at a designated time.
