What a ridiculous app. So many ads you cant get anything else accomplished. Why would I even remotely consider the paid version when I cant get past the ads to even try the free version. And its not like Google makes it easy to get a refund. This app needs to listed under ADVERTISING, NOT ELECTRICAL. There are REAL apps for professionals available, however you wont find them on google play. The professional apps dont target you for ads.

Great app, use it all the time. One request of change would be to allow the option to hide references that do not apply. For example, there is no need to show IEC and CEC in the US where NEC applies only.
