Hi All. I am soon to publish a freemium style app where the app is free to download, with a one off purchase required to enable some premium features. In the current codebase its just a premiumFeatures boolean that calls the google server once and caches the result locally forever.

This means creating a hacked version is fairly easy for a relatively experienced developer.

I could enable checking with google all the time but that requires an ongoing connection and risks genuine users getting locked out occasionally.

I am curious what solutions people are using to try and avoid this?
