Not the real museum app. And not free.
If you are here, you are probably looking for the Rijksmuseum’s app. That has the name simply “Rijksmuseum”, with logo showing “Rijks” in white letters on a black background. It provides guidance, maps, online pictures, etc. THIS app is completely different. It offers nothing but advertisements to pay $2.99 to get their version of Rijksmuseum information along with “special deals“. If that’s what you want, fine - I don’t know how good it is. If instead, like me, you are looking for the real guide to the Rijksmuseum, prepared by the Rijksmuseum, then look for the app with the simple white-on-black “Rijks” logo.
