This should just be a paid app. You can't even see the basic exhibit information without paying $2.27 for it.
Had it installed for my coming visit to Berlin. But it is ridiculously limited. Only very few items are shown in the free version. There are some explaining texts, but I guess when I'm there I will get as much information. This is an app that is supposed to show items from a museum! Museums get support from the state and that should cover the cost. Maybe some small entry fee, if they have to. Deinstalled it after giving it a try for some minutes.
Only 20 pictures... Even not HD. Slow app
Too little info
Helped a lot.. Would definitely recommend it :)
Works well with my phone. .
