I loved the free portion of this app. I told myself if I used it often enough, I'd like to subscribe. But I was a student and couldn't afford it. One day I felt I needed this apps help again, and looked for the free sleep casts at 4am on a night I couldn't sleep just to find that it was all locked behind a pay wall now. For something I use once in a few months, I'm not paying a yearly or even monthly sub. I did really like this app. Please give back the free casts.
