Doesn’t function as standalone app, just use your browser; don’t purchase.

I use Google voice and Hangouts all day long for work, typically through Safari. I saw this app and thought it would be a great standalone app that would free up a tab or enable me to close the browser. Nope! This doesn’t function as it’s marketed, I’ve tried to contact customer support three times without a single response. Bottom line— Don’t waste your money.

Hangouts plus disatisfied about Chatty for Google Hangouts
