I have this app it’s totally helpful, I use it all the time.
Conduit calculator not working!
I love this app but recent changes/upgrades has left my what conduit size calculator not working. Please help, it’s the most used tool I have in the app!!
I like it
If you know what your doing this app is great. It can use a few minor improvements that I'm sure will come. It helps me do some quick calculations easy, and that's what technology's all about. I have about 10 electricians that work for me, and I will recommend it to all of them with I phone's. Quicker calculating and less mistakes. means more $ in my pocket, in return More $ in the journeymans pocket. ;) worth every penny. Ps. This is the 2nd app I ever wrote a review on. I phone user since the beginning. Thanks for your hard work on the app!!
