I want to create a salesforce 1 App. How can i create it? I am not getting any option of creating salesforce 1 app. Is there any option of creating app.
To see the new "salesforce 1" style UI, login to your org and enter /one/one.app (e.g. https://na15.salesforce.com/one/one.app). Essentially existing content is presented in a format more suitable for mobile devices and there is various additional configuration and programming you can do to make that mobile experience better still. A native app is provided for iOS and Android that just acts as the container for that (essentially HTML) content.
