How these are counted

Each market shows its most-repeated complaint and how many apps share it. A complaint is only counted when it appears in at least 20 reviews and in half the apps of its category. A problem concentrated in one app is that app’s bug, not a gap in the market. Every market opens as a panel over this grid; 29 of these 30 also carry a full Deep Report: the €9 analysis, already generated and free to read, linked from the top of the panel.
