| 2024-09-19 |  | | Best app ever since for engineers love your work and the way things are you really deserve a 6stars |
| 2024-06-26 |  | | I am a HVAC instructor and use this app all the time with my students. Thank you. |
| 2023-02-22 |  | | Great utility for learning about the properties of many refrigerants when you're learning. Even better tool when you're a pro. |
| 2022-08-14 |  | | Does exactly what it's supposed to. With the convenience of the Slide feature, you can dial in what you're working on. |
| 2022-06-04 |  | | Super cool app. All the industrial refrigeration techs I work with have it. It's a lot easier than carrying around different PT charts in your wallet. Also has manuals and documentation on all Danfoss products so if you run into an ICAD or EKC controller and don't know parameters you can access then through here. |
| 2022-03-15 |  | | App works great for what I do. Happy to have this little helper with me at all times. I would recommend this app for all technicians but especially anyone new to the trade. |
| 2021-10-21 |  | | Not a good one, it doesn't work as it's say, I tested the magnetic tools to placed my phone on pump the red/black ring on phone screen rotated twice and then stopped, I recalibrated but same thing happens again and again. |
| 2021-08-27 |  | | Took a brief look through this app to see if I wanted to keep lt or not it Took me 30 seconds to realize this app is Hadassah. Extremely happy and it's simply easy to use snd understand. 10 stars |
| 2020-11-18 |  | | To the mentors at Danfoss. I find this an invaluable tool in my training programs. It is a kick start for a Danfoss learning initiative in the students. Although I do use many more of your engineering guides, this is the most prolific interest generator. Great stuff DANFOSS |
| 2020-03-10 |  | | The latest update causes the app to not work correctly once you have gone into another app. When you go back to the refrigerant slider app, it is completely frozen, requiring you to close it and reopen. Tried resetting the phone (Samsung galaxy note 5) PLEASE FIX |
