Virtual tours of art/photo galleries using apps

[DriedStrawbery]

Was visiting an art gallery this weekend to study some art work. The audio tours that were using special audio equipment (in olden days) is now moving to phone apps. The app i installed had a picture of the artwork and small description of the work, its composition, its story etc.

We can technically browse other galleries virtually and study the work... wanted to check if the community already has a few known galleries that offer such (free) apps.

Thoughts/comments?
Thanks.
