### 5/5 — Amazing!!!

*2026-03-05*

This app is incredibly helpful for me and my patients. I am a medical equipment technician and set up a lot of people on home oxygen. I refer to this app almost daily as it helps me learn the duration of the tanks based of liter flow and tank size!!!

### 5/5 — Great app!

*2013-03-23*

Not sure why there aren't more reviews on this app. For healthcare providers it is awesome to have a quick reference like this. And it's free! I will be recommending all my employees download it.
