I’m not sure how this is any different than logging into Gmail via any web browser. Basically this app is a web browser that can only access one website: Gmail. It’s the same functionality as accessing Gmail through any web browser. Certainly nothing special. I’ll keep using the stock mail app on my iMac. Works just fine for me. I used it for about 2 minutes and then deleted it. It’s nothing special.
