First if all I have to say the app is great. I am really happy with it. A lot of features are already implemented and work well.
Some small thing that I think is needed is a way to change the font size. As it is right now I find it very small and a bit hard to read but it’s a preference. I think there should be an option under sertings to change between different sizes: small, medium, large etc
For me the font in compact view is fine but the font when you read a post or comment is a little too small for my taste and is harder to read as I need to focus a bit too much.
This shows why it should be a preference!
Also the line spacing in comments should be a tiny bit higher.
The font on posts also seems small on my iPhone 7.
