Right after installing, I noticed that whitelisting apps is such an important and basic feature which you made available only for premium users. This is such a ridiculous decision for a "google play editor's choice app" that im not even gonna bother trying your app any more than 1 minute. - Update: No it's unacceptable that your development team didn't predict the flow of new installations and didn't include any kind of trial period, but fine i'll up my rating to 3 neutral.
