Save collection in iOS app for offline viewing

I agree this is Needed! LT, please consider adding the ability for users to download their library for offline use.
I was at a large used book sale in St. Louis yesterday, and there was no wifi AND I could not access my cellular signal, even outside the building. I could not check if I already owned the books I found. If I could download my library as a backup for book shopping times, when I may not have access to the Internet, that would be a huge help!

Offline access has always been requested but has never been a priority from the developers. You best bet would be to export to a spreadsheet and save it to your phone.

I agree that this would be extremely useful. From time to time I do find myself in a bookstore where there is neither wifi nor cellular.

I am a software engineer by trade. Perhaps there is some way that I could help the developers with this?

Can I double down on this request for the Android App as well
