I just found "Salesforce1 simulator" from google chrome App store. And for me it looks exactly similar to the App Salesforce1 provided by Saleforce and works perfectly fine as a Mobile App for My DEV ORG.
Anyone used this tool/App before? Can we trust it as a safe one and Can we use this in Multiple Environments - Prod/Sandbox(can see another APP for Sandbox itself)/DEV etc? Can we use this for both Android/Windows/IOS mobile App testing? Any limitation that we need to consider?
Any help is appreciated? Attaching a screen shot of this Simulator from my browser as well.
