It doesn’t give you any data that apple health doesn’t give you. It just puts it into charts and graphs that are larger and details are explained below the charts for people who can’t read a graph. Not worth $40 a year. After receiving the developer response they said it gives me data that apple health doesn’t give me like sound recording and classification. But why do I need to record my sleep when apple health just listens to my sleep and tells me what it hears. I don’t need to listen to 4 hours of my sleep sounds. But i want to, free record button on my phone. And they brag about the smart alarm options. Yeah I got a a clock app that does that and apple health has smart alarms too. Ohh and the sleep aid library. It’s called background noise and tips on sleep. We got that for free too. Pillow wants a stupid crazy amount of money for the same thing you get for free from apple. Yeah it may be on 3 different apps. But they are open anyway and it’s the same apps that pillow uses to gather the info and give you the feedback it’s using. Save your money. I used pillow. Not worth the money. A 99¢ a month app maybe, a $10 a year app sure. But they crossed that reasonable buy when they filled the app with the same basic info you get free with your phone and charged you have 3 free apps in one ridiculous priced app. Just my opinion. Glad they asked me to offer more insight.
