It's a simple and portable editing tool for web engineers and designers.

- Send e-mail / iTunes file sharing to export.

That's all. JSAnywhere is minimal forever.
Happy coding!

Nice app

I like the app, i'm trying to learn about JavaScript, i only have my phone but i wanted to learn it so bad and this app helps but i would like you to make the texts have different colors depending on what they are for, so that we can know where everything is easily, because making the entire text one color is kind of making it a bit hard especially to me since i'm a beginner.

See This please ,

Love it but a request...

I love the app and it is super useful but i would love for you to be able to click a file in download and press ‘edit’ to edit it and click which file to replace and have a full file structure and so its not a download folder you start in main folder and build from there!!!

Some Ideas

Here is an idea I think you guys/gals should add to make the Editor more appreciated.

You made it possible to add your own pictures to the editor, but you can’t add videos to the editor. I think it would be great and people would like it if you made a video downloader, just like the image downloader but you would download YOUR OWN VIDEOS from photo-library.
