ad-free version available?

Is or will there be any version available which I can purchase without advertisements in it?

Yes, at some point in the future we will also release an ad-free version of Robo Miner.

But it will not be available at many stores, just because it means so much work to maintain the different stores and also all of them works differently we will release the paid version only on choosen stores.

But that will happen at some point in the future, to speed up the fixing of any issues with the current versions.
