Bizarre. Thought I'd try this app as it comes up a lot when searching. I downloaded this as apparently there is content for free but found none-all had padlocks on. Also really odd is I've seen a fair bit of the paid content in other apps for free. There isn't a lot there for those who do pay and I'd be pretty unhappy if I were them and realised I could get a lot of the content free elsewhere. Uninstalling and using other totally free apps.
