hard to cancel trial
That cancellation link which is sent to us via email once the user has reach to you via email (is this year 1999?) should be visible on the "account" page. Why is it not? Looks like your are making it hare to cancel on purpose (when purchased via the website, not on the app store). Real problem? Most ads link to a direct test followed by the signup trial phase on the website. Only then the user is being told to download the app. Not cool.
