Used the Lifetime tariff in MobileAction. I also recommended this service to my friends. It was a perfect solution for non-professional ASO users.
However, one day they decided to limit the features I had access to when I purchased Lifetime access. Moreover, at the moment even the free plan has more features. Everything you need to know about the company's policy towards its users. They didn't send any message about these changes. Nothing. Just restricted access to purchased features.
I think it's great how we don't have to jump from one course provider to another to simply learn about different aspects of Mobile UA - even though they are all intertwined. Having all UA channels covered in a single place was something that I believe was well overdue - that too directly from experts themselves. That too free?
Good Job!
