Comparing Google Hangouts vs Viber is like comparing apples to oranges. Because your business is unique and nobody except you can decide, which is better for your company. But we can add some fun to your research and suggest some new comparison parameters.

Let's start with videos. We think that Google Hangouts has better video than Viber

Ok, now let's compare the UI. Looks like Viber has more user-friendly interface than Google Hangouts because it's bigger. At least on our screenshots

To compare the popularity of the solutions we counted how many alternatives people search for each of them on the Internet. And it turns out that Google Hangouts is more popular than Viber

Now let's look at the recent activities of our competitors:

Looks like Viber was recently more active than Google Hangouts (at least in our news). We also found some news, in which Google Hangouts and Viber meet head to head:

2017 - Viber introduced secret chats with self-destructing messages - a new advantage over Google Hangouts

Viber for iOS and Android got an update today that brings “Secret Chats” to the service for the first time. Like Snapchat, Facebook, Telegram and many others before it, Viber now enables its users to set a timer for their messages, after which they will self-destruct. The new feature also alerts a user if the person to whom they are talking takes a screenshot — that’s another feature that Snapchat pioneered. Viber appears to be pushing its security credentials in a bit to differentiate itself from the rest. It added end-to-end encryption and hidden chats last year.

2017 - Google splits Hangouts into Chat and Meet. Viber should better react

Google is making massive changes to Hangouts to make it more business-friendly. The service will be splitted into two separate apps: Hangouts Meet, a videoconferencing app, and Hangouts Chat, a Slack-like messaging app designed for teams.  Meet is a revamped version of Hangouts' video calling features, with a few new additions designed for businesses. Like the old Hangouts, it supports video calls of up to 30 people and participants can join via their desktop or the mobile app. While anyone with a Gmail account can use Meet, Hangouts Chat is just for Google's enterprise users. Essentially a full-on Slack competitor, the service allows teams within organizations to chat and supports a variety of third-party integrations, including bots and other productivity apps. Google also created its own bot for the app, which will schedule meetings on your behalf.

2011 - Google adds video chat to Android. Skype already enables video calls between Android and iPhone. Viber keeps calm

Earlier this year, we forecast the active competition between Skype and Google for the mobile video chat market. And the companies justify our expectations. Yesterday Google launched the (wireless) update of Android-smartphones, that adds voice and video chat to mobile Google Talk. At first Nexus S models will be updated, then all other devices running Android 2.3 and higher. Built-in video chat on Android will work via Wi-Fi, 3G, 4G networks, and will allow to call from a smartphone to GMail and back. Recall that the operating system for tablets Android Honeycomb already has in-built video chat. Meanwhile, Skype is already ahead of its competitor - it already offers video chat for Android and iPhone, and even lets you make video calls between these devices.

Google Talk Android
However, for now these features are available not in the Skype's mobile client, but in Qik that was acquired by Skype in the beginning of the year. Qik works on Android 2.1-2.3.3, iPhone, iPad 2 and iPod touch with cameras. In addition to video chat Qik allows to to send video mail and upload videos on Facebook, Twitter and YouTube. But the video mail will be free only until June 1, 2011 After that you'll need to pay for monthly or annual fee.

And while Google and Skype are learning the basics of mobile video calls, Fring for couple of weeks completed testing its multi-user mobile video chat and made it publicly available for iPhone and Android:
