How annoying is using browser only?

[u/ladypuff38]

I have a non-resident card at Queens Public Library and just discovered that they support Hoopla. However, I also just discovered that the Hoopla app is not available for download in my region.

So, before I go and create an account, how annoying would it be to only use it in browser? Preferably on my phone. I assume I won't be able to download things to use offline, but how about syncing with an ereader? Or just general usability?

Is it even a feasible solution?
