But then you don't understand charities... that money has to be spent. And also builds competence. Maybe 3% now, but with a goal of 10%? Then we are talking millions of people.
Not sure I follow. Regardless of competence or whether "money has to be spent", if that 3% did not have a native mobile app to download, they would just use the mobile web app instead. Why not spend the money on the non-native offering and make that better?
Well, hard to say without knowing what goes on inside of the Wiki foundation, but I assume their ambition is to continue growing the native app. After all, most people prefer a native app feel (they don't necessarily always use it though - partly due to apps sometimes not reaching their true potential, and sometimes due to discovery is harder).
By the way, everywhere I've worked the traffic to mobile native has been around 3% I think. Engagement is much higher than with other channels mind you, so maybe that's it.
