New update

@devteam App is great however. The newest update has left the app broken and a blank black screen on the newest iPhones making it unusable

Junk

Calculator is haywire. Not user friendly.

The only app around

This app is perfect for any Canadian electrician looking to speed up their workday! Can’t say enough about the creator! Always looking for improvements and caring about customers. Made by an electrician, for electricians.

Response from developer

Really appreciate that Jordan, if there’s anything else you need or want in the app I’m always available!

Great app

For the CEC it can be hard to find decent apps and or websites that will refer to it but this app is such a fantastic tool to use

Response from developer

Thank you for the feedback. We’re glad you’re enjoying the app and appreciate your support! If you have any bugs or feature requests email us at software@thesparky.work

Keyboard issues…

Amazing app, been looking for something like this for some time. Only complaint so far is there is no keyboard hide button when using the transformer tool, so you can’t press the “next” button. This leaves you stuck at the first page of the transformer tool.

Response from developer

Thanks for the review Nick! We’ll have an update for that out ASAP and update our review response to let you know. Thanks for the bug report! EDIT: This bug should now be fixed!
