@Mehrad Hey! It's basically an RSS reader, although I don't like to call it that since "RSS reader" comes with a lot of pre-concieved ideas about how it should work. So I prefer to say it's a way to keep up with content quickly without doing so in an addicted/impulsive way. If RSS was no longer a good way to achieve that (although it is), I'd remove RSS support.
Re Premium, here is a screenshot from within the app. The only reason it's not on the landing page is cause I haven't had time yet!
@booligoosh what it is? What services it provides? I failed to find a description page to read about it. Also considering that there are “9 premium users” I looked for a page to explain the tiers and prices but I didn’t find anything.
The UI looks perfect and clean
