### 4/5 — Terrible interface, excellent information

*2025-05-18*

I’ll start with the bad. There’s no search function, not even location based, and streams can only be added to favorites by tapping on the map. Once added to favorites the list stays in the order streams were added, with no sorting possible. 

The best part of this app is that when you view a favorite, tapping on the first link at the upper right shoots you right to the NOAA stream flow forecast page.

With some enhancements to the interface this app could be much more user friendly.
