You should just make people buy the app instead of pretending it free, waiting till they download it and then spring it on the you have to pay or the app is absolutely useless. And it is. YOU CAN NOT USE THIS APP IF YOU DONT BUY IT. ITS NOT FREE. THEY DONT HAVE ANYTHING WORTH THIS APP. advertising under false pretenses. You say it's a free app but you can't use it unless you pay. There are plenty of great apps that supply sleep sounds. I don't NEED yours.
