No longer available sucks

This was an awesome app that I used almost daily, then Copeland took it away!! The new part in the Copeland app sucks, all I need is an old school reference chart and Check and Charge was AWESOME!!!!

This app was awesome. Now discontinued

This was my go to app for charging systems. It was very clean and things were easy to find. Especially liked having a button to quickly see a pressure temperature chart for whatever refrigerant I was working with at that moment. This app has been replaced with an app that overcomplicated everything. 😔

Doesn’t work anymore

Used app for the past 8 years. Made the app useless and via a different app. The ads were one thing but this is just wrong now.
Uninstalled after being a long time user, will not be switching over the to Copeland app.
