Great app for Hangouts (Google Talk) but not Voice

I was looking for an app for Hangouts that I could use my Google Voice. This is a great app to chat on Hangouts, but doesn't integrate Google Voice like Hangouts does.

Fantastic! Full-featured and reliable.

I tried IM+, but it had a confusing interface and had trouble running in the background. I tried "Chat", but it spammed alerts whenever I lost my internet connection commuting, and required a tedious reconnection process. Mercury is my chat app savior! It's full featured, supporting off-the-record and image embeds seamlessly. It's also been reliable, un-intrusive, easy to use, supports Win 8.1 dynamic split-screen sizing, and looks good.

The Best Gchat for win 8

Really the best gchat client. Beautiful UI; toast notifications; in-line photo and video sharing, just awesome. And as an added bonus, developers are very responsive to emails!

Works great

Much better than the other google talk messenger I tried....very clean design and seems to be stable.

Solid app with room for improvements

If you need a solid Gchat/Hangouts messenger in the Metro interface, you can't go wrong with Mercury Chat. It has a clean interface, and it performs without noticeable issues. Big area of improvement for me would be the rendering of messages on higher resolutions. I'm running a Surface Pro, and I can full screen the app or have it taking up half the page and I don't see any more of the conversation than I would if I had it snapped to the smallest column to the side... why is this? Why not render the messages so that I can get more than a few lines of text on the screen at a time? I do a lot of long form conversation over the service, so this is really important for avoiding scrolling up and down constantly...

Good support, good app

I had a serious problem with the app crashing on start. The support team worked with me to debug app and find problem which appears to have been server side. They have been very kind and helpful. I highly recommend this client for those who are looking for a google talk solution for windows 8 rt, if you have a problem with the app just drop them an email and they are very helpful with resolving it.

simple and does the job

it's a simple and clean google talk app. I like using it better than signing into gmail for chats. I think I'd give it a full 5 stars if it supported video

Best gChat app For Win8 I've used

Works beautifully locked to the side of the screen or in the background. I've used a few gChat apps, but this is my new favorite.

Problem with all chat applications

Every win8 Google chat application I've tested, this one included, has the issue that when the keyboard comes up -in either full screen or snapped view, the chat text scrolls up and out of view... very frustrating. I will buy the first Google chat application for windows 8 metro that doesn't do this.

Doesn't work at all for me.

It says it couldn't reach the server, but the server status page says everything is fine. Only 8 people connected though, so maybe I'm not the only one with this problem.
