### *---- "Unable to disable ads - Unable to use it."
The pay button doesn’t work. I was assaulted by an ad takeover ov my phone and audio. I had to close the app and reset my audio after the loud game ad was started.

UPDATE: Had to delete it. The ads are constant and annoying.
-- Overwater, 2024-03-26

### ***** "One of most useful apps in electrical"
Informative and useful in so many ways. Need to be sure to account for when the system of units and information is not USA but everything is there and all in one app! Great lighting tools and even diagram breakdowns. Thank you
-- Mchu1124, 2023-04-26

### ***** "Very informative. Even for Americans!"
An amazingly simple design and organization of topics allow me to find what I’m looking for. It’s also helpful when thinking through a layout.
-- Bite me, ESPN, 2022-11-25

### ****- "Really good"
I would love it if a explanation was given for all the symbols in the diagrams otherwise it's a great teaching app
