I would like to see in future versions a reset button at the end of the 'Pressure Calculator' to eliminate the need to have to back through all the selection screens to calculate another line. Also would be beneficial to be able to select between standard and metric measurements. ### 4/5 — Good *2013-04-21, version 1.1.1* Very good will be helpful when I need it ### 3/5 — Metric *2013-04-11, version 1.1.1* Metric conversion has errors. Easy to adjust settings for fast calculations. ### 5/5 — Great app *2013-03-09, version 1.1.1* Going thru cert driver op now and it's a great way to double check my math! ### 5/5 — Great Tool *2013-03-04, version 1.1.1* One of a kind app! Great for use on the fireground. Also a good tool for pump testing. It helps make sure my layouts are setup correctly. Thanks! Love it! ### 5/5 — Pressure app *2013-01-17, version 1.1.1* Very good app ### 5/5 — Cool! *2013-01-16, version 1.1.1* Easy enough for even me! ### 5/5 — Easy *2012-12-27, version 1.1.1* Perfect exactly what I was looking for its fast and easy ### 5/5 — App *2012-11-15, version 1.0* This is great, very user friendly!

Thank goodness I didn’t pay for this... wait.. I did 😡 ### 1/5 — Crap *2014-11-23, version 1.2.2* Won't open, useless. Don't purchase!!!!!! ### 1/5 — Fix it or money back *2014-11-05, version 1.2.2* Will not open. ### 1/5 — Won't open *2014-10-31, version 1.2.2* Totally useless app. It won't open ### 1/5 — Not that good. *2014-10-19, version 1.2.2* Don't know how this app is suppose to work. Won't open. ### 1/5 — Fire Flow/Pump Pressure Calculator *2014-10-06, version 1.2.2* Cannot get it to open-so I have no idea how good or bad it might be!!! ### 1/5 — And.... *2013-09-12, version 1.2.1* So, it is a nice looking app, but I guess I wanted more than what it does. Yep, it will tell you the operating pressure after inputting all the variables, but it seems a little cumbersome. Some will find it great, just not an app for me. ### 1/5 — Metric? *2013-07-25, version 1.2.0* What happened to the metric options for us Canadian Firefighters? ### 2/5 — Seriously. What did happen to the metric option? I'm deleting! *2013-09-03, version 1.2.0* This is exactly what I was looking for! A simple app to make quick calculations for me as we have several different nozzle types on our trucks and our 'pump charts' don't address all of them! ### 3/5 — No 2” attack line calculator *2021-03-09, version 1.2.3* This is an excellent tool if you are using the old fashioned 1 3/4” and 2 1/2” attack line setup on your apparatus. However, there is no calculation method for those that have the more modern approach of a 2” attack line. Hoping the devs can fix this issue with an update as more and more departments are turning to 2” attack lines as they can achieve what we use 2 1/2” for with much less physical effort. ## Most praised reviews (10 highest-rated) ### 5/5 — Nice tool *2020-08-20, version 1.2.3* I find that this has been a useful little tool for pre-plans for flow calculations. I also started using it for in house teaching as a quick reference. I think it’s worth the purchase. ### 5/5 — Pretty dang good! *2019-05-21, version 1.2.3* I think this app is pretty awesome! Wish it had 1” hose calculations as well for our wildland applications, but I’ll live with that ### 5/5 — Great App (developers please read) *2016-01-14, version 1.2.3* Very handy app but I'd like to see you add 2" hose to the calculator. Starting this year our rig will be carrying 2" high rise packs. Thanks!! ### 5/5 — Does what it's supposed to do - when you need it to ! ! ! *2015-08-25, version 1.2.3* I've tried a handful of fire-flow calculators and most of them are more flash than bang. This app actually produces the info that you will need on the fire-ground! It does it with a minimal amount of input - making it meaningful - when it counts! This app is practical and simple to use - and it produces results. ### 5/5 — Great App *2013-07-22, version 1.2.0* Great reference tool ### 5/5 — Very easy app *2013-07-20, version 1.1.1* I love it use it all the time ### 5/5 — Grade A *2013-07-20, version 1.1.1* Exactly what I was looking for. Awesome training and preplan tool! ### 5/5 — Perfect *2013-06-09, version 1.1.1* Perfect for the operator of an apparatus or for basic study! Plan to use it on the job. ### 5/5 — Simple and effective *2013-03-27, version 1.1.1* Very helpful and easy yo use. It does what it promise! Good job!! ### 5/5 — Assistant Cheif *2013-03-11, version 1.1.1* Handy tool for training. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
