### 4/5 — Nice replacement

*2025-02-25*

I had paid for an app Riverdata, do a lot of fishing, nice replacement to my old app.  Live and die by the river flows, once you get the weather tied in, would go from 4 star to 5.

**Developer response:** Weather is tied in!

### 5/5 — Straightforward and reliable

*2024-01-13*

A great app for flow data. Highly recommended.

### 5/5 — Really wonderful app

*2023-08-28*

I’ve really enjoyed this app. It’s fairly straightforward to use, and the custom level feature is kind of a novel concept in this type of app. It would be really cool to have a home screen widget and/or an Apple Watch complication from this app.
