Rely on this app every week it is so helpful and easy to use

### 5/5 — Pillar sparky

*2019-05-07*

Great app

### 4/5 — KVA calculator

*2019-03-25*

Good basic app. Does what it is supposed to do. One nice upgrade would be to provide available fault current when the impedance is provided. Doing this through a step menu would truly enhance the app's value.

### 1/5 — Do not buy -- doesn't work

*2014-09-26*

Don't buy this app- needs nimblekit dev software to run- should be pulled from App Store - waste of money --- does not work on iPhone -- not happy

**Developer response:** App now updated for iOS 11, removed nimblekit & new UI redesign.

### 5/5 — Great app

### 4/5 — Now works in iOS 6

*2012-10-15*

Great little app to have handy if you need kva calcs. They updated it for iOS 6 and it is working pretty good with occasional shut down on a 3GS iPhone. Looks like they may have to tweak it a bit to be back to its original reliability.

### 1/5 — 4S
