As of today, Apple is raising the Euro prices for all price tiers. This means that the one-time purchase of pianoscope standard and pro will be about 17% more expensive in the European App Stores. Unfortunately, Apple does not allow to define different one-time purchase pricing for different countries. So I am not able to lower the prices without affecting the pricing in all other countries.
In contrast to this, the subscription prices for pianoscope pro remain the same for all countries.
