🌚 Dark mode for enhanced visual comfort
Also included
➡️ Free downloadable transparent device mockups
➡️ Option to switch to landscape mode
➡️ Zoom just like on a real mobile

Mobile FIRST has been the most powerful and reliable simulation extension for over 5 years.
Our rating on the Chrome Store speaks for itself.
✨ It integrates many technical tricks to reproduce the mobile experience as closely as possible.
Of course, this does not replace testing on a real device at the end of your development for full validation.
