### 4/5 — Pretty good!!

*2021-12-20*

I love this app! It’s the perfect pocket reference. Would be nice if they added resistance band color converter as well.

### 5/5 — Impressive Set of Calculations

*2016-06-08*

Very Impressive! All the necessary calculations for electrical installations. I like the formulas being shown also. Maybe add an option to copy the formula and the results for generating reports. Remember to consult the NEC handbook.

**Developer response:** will try to add these features in the next update

### 3/5 — Needs more calculations

*2015-08-19*

Needs converting KVA conversions. To and from.

### 5/5 — Wow very nice app

*2014-01-04*

Where was this app when I was in electronics school!  Makes my life so much simpler. It has all the needed calc's and then some more!  Great job.

### 5/5 — Great app!

*2013-09-21*

Great app for the tool kit!

### 5/5 — Champion

*2013-01-27*

Very good app, worth the price and recommended.

### 5/5 — Rams30

*2012-08-29*

This is probably the best engineering App that I have bought. Covers everything related to electrical paramaters., and I'm really impressed..). besides some 40 odd calculators, It has got a converter too. and you can convert the result to any units as u wish.. the series, calculators, all single and three phase calc, storage calculators, and  energy cost calculation. ,are really good. my fav thing in this .. is the beautiful depiction of formulas,  ..Three Cheers and Five Stars to this team. Well done.
