## Flow Test Calculator Reviews in United States

### *---- "iOS 16.3.1"
Can’t read the results on my iPhone12. It used to work😠
-- D.r.u.m., 2023-03-29

### ***** "NEEDS UDATE!!!"
Great app. Use at work quite often. Tried using it the other day but will not open because it needs new update for the iOS.
-- Texasmudd71, 2021-06-24

### *---- "Flow Test Calc"
So I buy the app it doesn’t operate with my phones iOS. 

You going to support your product with an update ?  
    As for the product itself. I compared flow numbers using a calculator & this app. if the formula is correct they should match. App worked  flawlessly  easy to use as well as versatile.  Could flow 2 1/2” port or 5 1/2”  If you update the app I would absolutely give it five stars. If your own products  aren’t worth your support. Then don’t look to me to support this or any other products produced by this company. Why should I support a product produced by people that do not care enough to support it themselves? I gave it one star because if you don’t update it is nothing more than a one hit wonder. Which of course makes me wonder “if it’s that way with the app I purchased why would any of the software applications produced by this company be different. “. need an app it’s going to work over a period of time specifically more than six months look somewhere else. “ would be the advise / word of mouth advertising you receive  I will support your products with an upgrade of my review if you show your “products” are worth your support

### ***** "Update Needed!!!"
The Apple update to 14.6 iSO will not allow the app to open or work. Do ya have plans to work an update so I can keep using your app for my business? While you are there would you consider to auto populate the flow based off the pitot? Not necessary but would be convenient! Please let us know you are planning your update!

### *---- "does not work with new update!"
should have read the GD reviews before i paid for it 😬
-- Willisdog4006, 2021-06-07

### ****- "Needs update"
This app works great but needs to be updated, hopefully you can make this work again for iOS 14.
-- Football Fan 4786, 2021-05-21

### ****- "Needs updating to work with iOS 14.5"
Will not open on an iPhone using iOS 14.5 which is the latest iOS. Hope you can make this work again!
Thanks!
-- Cupcarz, 2021-05-04

### ***** "Daily"
I use this app everyday!! Love it!!
-- DDalton757, 2021-04-22

### ****- "Great App For Calculating Hydrant Flow Pressures"
Great app to use out in the field for fire hydrant flow testing
-- HydraFlo, 2021-04-01

### ***** "Great app need across multiple platforms"
I use this app frequently for work and I really like the app. The problem is, this app is only offered on Apple phones. I can’t find anything from Samsung that does exactly what this app does. So in order to continue to use this app I have to keep an Apple phone when I’d like to switch back to Samsung.
