3/5Powder Factor Calculator Off
Used to work great but after the last update the powder factor calculator will give you different outputs even though all your inputs are the same.

5/5Great app
Appreciate the update on a great free app that supports the explosives & mining industries.

5/5Great Company, Superior App!
Very impressive app, and extremely useful. Nothing beats access to information and tools provided direct from an expert source. Now it's truly easy to tell people about this Company / resource. The app is quite slick, nice design and type give the elements within, a unique touch. From end-to-end a very functional app. This was a smart idea to bring into mobile. Great job on the app and, congrats to all for the well accomplished work you do.

5/5Best Resource for Technical Info on the go
This app is great for anyone involved in the industry. I've recommended it to ATF agents, other mining groups, and all blasters and those involved in procurement. The technical library is great. I prefer this app over all others.

Best app in the industry for real use in the field. These calculators are intuitive an useful, not just eye candy functions with little use. Great app!!!
