### 4/5 — Download data

*2023-03-27*

Its a good app. I wish it was easier for me to download the data. To get to the last reading you have to scroll forever to get to it. Especially if you have a lot of water perimeters to go through. It will be nice if the most recent data was on top of the list instead of the bottom.

### 5/5 — Sutron Linkcomm

Very easy to use product, which offers ability to manage Meteorological & Hydrological Stations at the touch of a smart device screen...!!
