Ratings and reviews

I have owned this app for many years at this point and it has always been one of the best tools on my job. I use it to simplify the process of finding the offset and bend angles for my run to suit pipe jobs(1/4" up to 1" piping) The recent update has eliminated the angles from the normal offset calculator forcing me to once again do math the longer way. Unhappy to lose that functionality!

Union steamfitter here: The multipliers on this app are flat out wrong. For a 45 offset you want to multiply the rise/run by 1.4142 (or 1.4/1.41/etc). I can understand a little rounding here and there but using 1.5 as your multiplier could result in disasters in the field. Even when I set the multiplier to the correct amount, however, its take-offs for 45 fittings are also wrong, usually by about a 1/2" overall. Not a huge deal but it could be in tight piping situations. The app needs work

after the latest update all dimensions in the drop box are blacked out near impossible to use the app. Thankyou for the dark mode user update. it works perfectly

What’s new

Minor update for dark mode users. The drop down menus were all black. That should be corrected for anyone using dark mode.
