Recently I started looking for an app that would take GMail out of my browser and give it some additional features like true default app support. I finally settled on Kiwi for Gmail (formally GMail for Mac).
This started life as a Kickstarter project and after destroying their funding goal released version 1.0 a few months later. They had some issues with the original name and were forced to change to what is now known as Kiwi for Mac.
The app itself is fast and lightweight compared to other apps that offer the same benefits to GMail users. It memory footprint is small as long as you close it on a regular bases however this is a problem with GMail in any web browser.
In terms of additional features it offers for GMail on the desktop beyond having system wide default mail app support and multiple accounts in tabs Kiwi doesn’t offer a great deal. They do say support for a number of popular plugins is coming soon however I have never really been a fan or long term user of any of these.
The main advantage for me is getting GMail out of my browser tab bar and giving me a dock icon, badge, default app and notification centre support. If you love GMail’s web interface and want to get these additional benefits the Kiwi for Gmail is the way to go.
