I have been using this application for no more than a month, but I have already managed to appreciate it.

What I like about this application is its simplicity, reliability, and functionality. The author of the application, Anatoly Tarasenko from Ukraine, created the ability to work in three languages: Russian, Ukrainian and English. The program has a “Smoke Break” section, where you can play domino solitaire or read reference materials.

The application also has some disadvantages, but they are very small. For example, there is advertising, and it cannot be removed yet, since there is no paid version. Here is how the author himself describes this problem:

This application, in my opinion, lacks more extensive reference materials(but then it will be a whole electrical encyclopedia ☺)! And it would be possible to add a few lighter themes. But this is nitpicking!

The application is so well and professionally made that there is practically nothing to reproach it with!

Say thanks to the author:
