Android is unrealistic right now, as it pretty much will require a total rewrite. We do hope to expand on more iOS and Apple platforms though (like apple TV and Mac). I do get your frustration with Apples $99 yearly fee. However there are some reason behind it. Apple uses it as a filter so the app store is not riddled with junk. Also, you generally get "better" users on iOS than you do on android. And by better users I mean users who are engaged, more likely to play, more likely to appreciate the product, and just overall more rewarding for the developer. There is a reason why most major app releases are on iOS first.

Received your email and responded. Make sure you cancel through the iTunes/Apple subscription pages. https://support.apple.com/en-ca/HT202039 We don't have control over subscription billing, that's on Apples end.

You can't delete the items on that list. Also, there is no storage space for that. So there is nothing to really worry about.

Is it still not working?
