Museu Gulbenkian

It's great that you have audio. Please allow a full screen view of the artwork. Right now, the image is so small because one can't minimize/hide the text. It's frustrating since I choose to listen, not read. This way, the app would be useful while not in the museum standing in front of the piece. Also, allow swiping between detail pages and include thumbnails on the list view page

Please add a mode where I can turn my screen off and still listen to audio. It is pretty annoying -- having to walk with a phone with screen constantly turned on, even if I do not need it

You can't rewind/fast forward audio. If you leave app or switch tracks, you'll need to restart audio from the beginning. Also, if you exit app, audio stops. It doesn't keep playing in the background.
