### 4/5 — Great, but has one issue.

*2018-05-03, version 1.3.10*

The app works great and does what it needs to do. I would rate it 5 stars, but there is one issue that needs resolution. That issue is that when doing a quick-cal, you are not able to view/email the calibration report after you’ve calibrated. If the developer will fix this, I will change the rating to 5 stars. Thanks!

### 5/5 — Great App!

*2016-03-14, version 1.3.7*

Revolutionary groundwater and surface water app.
