Amazing app with two (significant) flaws

This app is free, and saves an incredible amount of time. It would garner 5 stars, except for two significant flaws: Firstly, you can only map one branch at a time, which means mapping a system with multiple branches requires you to restart for each branch.

Secondly, and most importantly, hitting the home button completely resets your progress. This makes the app almost unusable; if you stop to take a call or text, you have to start over. If this glaring issue was fixed, 4-5 stars would be warranted. On the other hand, this app also exists on Bussmann’s website, without this issue. For the time being, I recommend using the app there.

Two issues

Will not allow selection of 10kVA transformer. Will not email labels with iOS 12.
For my use, these are small problems that if fixed would garner the app 5 stars from me.

Bussmann fault app

This app does not work with the new iOS upgrade that Apple just put out to their phones, especially their older phones I agree with the previous review need to get this corrected!
