App looks good and feels good to use, good job.
Some UX feedback after initial use - I think the explore icon should be a Magnifying Glass. This UI is pretty standard on social/communication platforms for search/explore. For a brief moment I felt some friction looking for the search.
Small detail but any time UIs are changed it’ll introduce some resistance and/or friction and it’s an easy win in that regard.
Another possibility is just making search a standalone feature and expanding “explore” to contain things like reads, maybe even a vetted Micro App Store.
