Im a big fan of this app. I have found that Gmail can take up quite a lot of resources when open in a browser and can get hidden in the mess of tabs that often exist in all my browser windows. At a conference I had to stop leaving my Gmail open because it cut my battery life on my 11" Macbook Air by 3 hours, so effectively I was cut off from easy chatting and email unless I was willing to burn some battery. Ive found that Kiwi doesnt use anywhere near as much battery/RAM/tab space as using Gmail in a browser. So far so good, keep making the app better please!
