🌚 Dark mode for enhanced visual comfort
Also included
➡️ Free downloadable transparent device mockups
➡️ Option to switch to landscape mode

Mobile FIRST has been the most powerful and reliable simulation extension for over 5 years.
Our rating on the Chrome Store speaks for itself.

- Carlos Zambrano
- Very nice tool for mobile view, but you have placed too many ads that is making it buggy and very annoying to use, the modal ad I receive every refresh I made into my app to test the mobile view is super annoying and most of the times breaks the mobile view to not show anything. I will gladly change my rate if you find out another way to place the ads in a way that is not so annoying.
