Great tool

Every truck operator should use this as a backup plan for brain shutdown :)

Good app

I really like how simple this app is along with the look and feel. All of this makes it very useful.

If the developers could consider the following:

Add a third option that assists firefighters in determining true coefficients or true friction loss based on their actual flows. For example most hose is not actually true 1.75. If I perform a flow test I find it takes 30 psi per 100' to get 161gpm or 50 at the 7/8 tip. If I could input that 30 psi into the app and have it tell me the coefficient is 11.5 not 15.5 that would be extremely useful for firefighters.

Great.. But needs a little more work.

App is very easy to use, easy to read, and took no time to figure out. However there need to be additional tip sizes such as the 15/16" & 1 1/8" (both of which are very widely used in the fire service) as well as adding provisions for 2" hose with 2.5" couplings (rapidly gaining popularity & use in the fire service). Stuck between 3 & 4 stars, but went with 4.
