Just wondering, Is it normal to have a price in € cheaper on steam than android ? Not a real issue but it’s quite weird to pay more on phone 
I believe the differences is usually in how different platforms handle translation from the US Dollar to the Euro (or other currencies). and/or how they do their taxes. To my understanding Steam handles things regionally, while Apple and Android are more centralized. Plus (again, AFAIK) all of them do their own personal conversions to and from USD (obviously they don’t use floating numbers based on current conversion rates or the price would be hopping around by the minute), and don’t always use the same rates. So, I guess it would be expected.
