Heres my two cents worth
First off, let me begin by saying Ive been bending pipe for more than 40 years so I do know a thing or two about what Im saying.
The iBend Pipe app in its original form was a great app, straight forward and on the money. I recently downloaded the latest update, 4.0. Yes, the developer made a few changes in the app concerning the calculations. Yes, he changed from the "old fashioned" way to using the center of the bend. And I have been reading the reviews concerning this change.

Heres my take on what Ive been reading: if you cannot adapt the way you bend pipe, if you cant wrap your head around the fact that there is more than one way to bend pipe, if you cant make your bender work for you instead of the other way around, then you really dont know how to bend pipe. As I mentioned, Ive been bending pipe for over 40 years. The changes Ive seen in this latest update make pipe bending, especially saddles, a whole lot easier. If you would spend 10 minutes and look at the app the night before you have to use it you would be able to use it easily. When you are in a crunch is NOT the time to figure out how to do something. The developer has gone to great lengths to make our job of bending pipe as easy as possible, short of making an app that would bend it for us. Dont bad-mouth this app simply because it takes you out of your "comfort zone" and shows you another solution to a problem. If you cant wrap your head around the fact that there is more than one way to bend pipe, maybe you should step away from the bender and let a professional take over. You just may learn something, so long as youre not too stuck in your comfort zone. Or change your career path.

As far as the update is concerned, it is an excellent app. There is a minor bug (Ive already emailed the developer - very quick response from him, I might add) in that if you edit a bender the app doesnt save the changes and in order to restore the original values, you have to reset the whole bender list. Not a big deal (to this professional). Just need to remember to add/subtract the difference.
10 STARS if thats possible in the App Store.
