No way to cancel free trial. The app seems nice and well designed, but after trying it out for the free trial, decided it wasn't for me (the ONLY way to get any idea of the value of the content, btw...there are no free options available unless you sign up for the trial). I am trying to cancel before I get charged $69 for an app I don't want, but it is impossible to cancel through Calm and when I try to manage my subscription through Google Play, it is not showing up. Feeling PLAYED.
