I have reinstalled the App to see if that would help and no luck. I also verified that my IOS is up to date as well. ### 5/5 — Great software for plunger lift *2015-10-27* Industry should develop more software like this ### 5/5 — Great Tool !!! *2012-04-18* I was one of the first, lucky operators (sorry Jesse) who got to try this APP out when it was in its infancy, and this is a must for lease operators who work with plungers in the natural gas industry. ## Frequently asked questions about WMC Fall Rate Calculator ### What is WMC Fall Rate Calculator used for?
