Dutch only app
Great app for exploring the sights in Maastricht, if you can read Dutch. If not, you may still find some things worthwhile, especially in the restaurants and cafes section. I am not sure why it says English in the languages as there doesn’t appear to be an English section.
Language barrier
In order to make app useful to tourists, students, and internationals, it should be available in English. If it is, then the setting should be easier to find.
