Pro Good looking interface
Birdie has paid attention to details - cohesive icons, functional typography, color scheme that's easy on the eyes, layout and letter spacing that makes reading the feed comfortable, etc.
The app has just 5 tabs - home, replies, direct messages, profile and search. That's it.
Con Elementary OS focussed, might not work properly on other distros
The dev has decided to continue development based on Elementary OS APIs, entirely dropping support for other ditros. https://www.birdieapp.eu/building-our-future-on-elementary-os/
Con Limited configuration options
The tradeoff to Birdie's simplicity is that if you don't like something about how it presents the information, you most likely won't be able to change it.
