Matter Reader plug-in & IOS App

I’ve just discovered the app for IOS Matter Reader

Installed the Obsidian plugin and I like it. Automatically syncs your reading list links with highlights too.

Seems like it could be very useful, it is easy on the eye for reading items too. Has anybody else tried it on IOS? I am trialing Zotero too but transferring annotations to Obsidian requires desktop PC which I am trying to avoid.
