Well... do you really think that it is possible to evaluate a service according to the feedback on the Google Play store? 🙂 /I have looked there, it's more for fun, IMO/
BTW, it is interesting for me that in spite of I do not consider myself uninformed about situation in Polish business, I must admit I did not met Cinkciarz until now, although their story is impressive. But I do not follow these “top businesses lists” a lot...
I am curious about some experience︀ of a reasonably oriented person...
