my app called squash. Inspired by yik yak, https://en.wikipedia.org/wiki/Yik_Yak. The app is public but my back-end repository is still pirvate.
It features recyclerview pagination, location based subjects, location based sticky post, location based post, and anonymity.
The features being worked on right now are:
-bugs
-location post frequency heatmap
-more profile features
-image compression and image upload limits
-spam protection on frontend and backend
-more error handling to make things atomic
-twitter reply style post making
-dark theme, other settings
