Not sure why this app is necessary.
It does not give you offline access and is simply a browser window view into Gmail.
They layout is identical to what you see in the browser, and there is nothing truly unique that I could figure out comes with the app other than the ability to easily switch between accounts - which is not available in the free version.
In short, not what I was looking for.
