Should be a paid app.

Very impressed by this apps features. Remaining files using meta data is genius!

Constantly surprised

I’m constantly amazed at the capabilities this app has

Buggy

Buggy for large pdfs.

Doesn’t sync consistently with iPad

I love Zotero, so my frustration really comes with not being able to use it. I pay for storage, and recently files have been syncing inconsistently between my computer (windows) and my iPad. The documents are in the web app just fine.

Fantastic app otherwise!

There is one problem

I just downloaded the app for my exams and it cannot verify my email. It is getting frustrating.
