Nice design, buggy software, unresponsive developers.

Dont bother with this app, its not being maintained anymore, and the developers arent responding to any support emails anymore.
I actually wanted to use and like this app because it has excellent support for the Pinboard bookmarks service, and really powerful Smart Folders (which work great with the Pinboard bookmarks),
but their RSS module limits the amount of feed items itll display, and even worse, theres no option to keep read items. I follow some feeds which get infrequently updated, and this app removes all items after a while, presenting a completely empty feed. I raised all this with the developers, and emailed them multiple times: Not ONCE have I gotten a response. The last update to this app was July 14 in 2015, so apparently the developers have moved on.
