A simulator like

Hi guys,
Basically i am building and working on android and iOS apps. Every time i have to run the apps, i have to open in a browser and resize the browser.
Also im not using osenui , i am using materializeUI.

My computer is not powerful enough to run the app in my android and ios simulator while coding.

Is there any tool like a simulator, like onsenUI tool ? So i can be relax coding in peace with no worries.

Thank you s much,
Laurent Kouassi,

You can open multiple sessions on different tabs of a browser and use different form factor perspective to test responsiveness . –
