No, but most of the codebase can be reused for the mobile app using phonegap/cordova.

> Electron exist same reason nodejs exist webbies to scare to learn another language.

I hate this way of seeing "webbies" as a lesser kind of engineer. I've been on both sides, doing low-level development in C, full stack on .Net, and now Node.js, and I choose the tool that better serves me at each point.

Many of us choose to use JS/Node/Electron because of practical reasons, not because we are "too scared". You may think we are misguided, and we might very well be, but there's no need to be so smug about it.
