Google already twice tried to "break" into the niche of mobile messengers. Examples of this are Talk and Hangouts, which have gone unrecognized. The third attempt turned out to be more successful, because a really interesting application appeared on the market. Let's take a look at Google Duo, what kind of program it is on Android and how to use it.

What is this application

Google Duo is a mobile video chat with a very simple interface. In terms of functionality, it is very similar to FaceTime from Apple.

Note! Journalist Dieter Bon noted that Duo - quick application, which is not loaded with unnecessary functions.

The developers focused on the fact that the program does not require high-speed Internet, the connection will work even with a slow connection. It does this by optimizing WebRTC and using QUIC.

WebRTC (real-time communications) is a technology designed to transmit streaming data in real time (as we see in the example of Skype, FaceTime, Duo, etc.). QUIC is a technology that allows you to receive a stable signal even with the loss of data elements (packets) by aligning the boundaries of data blocks.

Features and Capabilities

Duo has the same functionality as FaceTime for Apple products, namely:

Video calls; audio calls.

But the advantage of the Google app is that it is designed for both iOS and Android.

The main difference from FaceTime is the presence of the "Knock-Knock" function, the essence of which is that you see the interlocutor even before you answer the video call.

Note! This function works only if the user who is calling is in the contact list of the person who will receive the call.

If you missed incoming call, a message about this will be displayed in the notification panel with the ability to call back with one click.

Although the functionality is minimal, the blacklist is still present. Highly useful function if you want to protect yourself from calls from any contact.

Customization

The setup takes as little time as possible.

By the way, pay attention to the permissions required for the program to work properly.

Advice! If you are very worried about your privacy, then you should refrain from installing.

On home screen applications, you can invite a user from your contact list.

Now let's take a look at the parameters that can be configured.

Deleting

You can delete a profile from the application by clicking "Delete Duo Account" in the settings.

Comparison with competitors

Since the program was created as an analogue of popular video chats, it should be compared in all respects with competitors, which are FaceTime, WhatsApp, Viber and Telegram.

Note! We asked 100 people to rate each of the messengers from the side of an ordinary user. Perhaps the comparison is not entirely correct, but the comparison takes place with the user's eyes.

Platform

Cross-platform applications (created for different operating systems) are more popular than those developed for a specific operating system. The more platforms supported, the larger the audience of users. Accordingly, having an Android device, you can fully communicate with an iPhone user.

Video communication

Making video calls is the main focus of Duo. The app handles it perfectly, even with a slow internet connection. As for the competitors, they are doing great with this function too.

Calls

Regular calls in instant messengers are not popular, which is caused by the low tariffs of operators for cellular communication... It is only worth noting that each of the applications in question has this function.

Posts

Communication via messages is an indispensable feature for a messenger application that they want to promote among users. Unfortunately, Duo does not have the ability to "write" with the interlocutor.

Easy to set up

An important factor is the simplicity and speed of setting up the program. Users like it when the interval from download to full customization occurs with a minimum number of clicks. In this regard, each of the messengers shows a good result, but Duo managed to slightly outrun its competitors.

General impression

Based on the results of the previous paragraphs, a general impression is formed. Each of the messengers has its own advantages and disadvantages. Comparing all the parameters, we get the following results:

conclusions

Summing up, it's worth mentioning again important point... We compared messengers, evaluating them with the user's gaze. Given that each program has different functionality, they cannot be compared as full-fledged multimedia platforms.

After examining the results, we conclude that Google Duo is an application that will gain a good audience due to the simplicity of the interface, good optimization and convenient features. But it will be difficult to compete with popular messengers, because some of them have more functions and users who are not ready to change the used application.

What messenger do you use? Why? (Share in the comments)

Google has announced Duo video chat, designed for personal calls in video format. The product is similar to a similar service - FaceTime, with the difference that given client will be cross-platform.

One of the exclusive features of Google Duo is considered the "Knock-knok" option, when the caller can see the interlocutor's image from the camera even before accepting the answer, thereby determining his mood.

Features of Google Duo

The profile in the Duo application will be linked to a personal user mobile number, so after installation you can see all the subscribers from the Contacts book who also use this service. Available:

• Simple and clear interface... When you call, you can display the video on the first screen, and the knock-knock function will help you understand a person's mood.
• High quality of calls. Reliable calls over Wi-Fi or mobile connection.
• Cross-platform. Allows you to chat with friends who have other devices and even an operating system.

Google Duo is an app designed for all platforms, so communicate in a simple, secure and fun way so you don't miss a single call.

Another "niceness" of the software client is the stability of the connection with a bad, intermittent Internet.

If the signal is weak, Duo will automatically reduce the quality of the broadcast video, and the video call itself will not be interrupted when switching between Wi-Fi - 3G / 4G channels.

Among other things, all video chats have a high encryption class. Even developers will not be able to receive images from the camera or listen to any conversations, since they will not have the decryption keys of the end user device, unlike Skype applications, which constantly cooperates with the authorities in this regard.

Google Duo is the default video calling app in newer versions. operating system Android.

Available functionality and benefits

Google Duo was created to make it as easy as possible to make audio and video calls. Calling the interlocutor is carried out by literally pressing one key.

It is very easy to understand which of your acquaintances uses this application - the list of such people will automatically go to the "Contacts" section after you give the application access to the Android phone book. To register in the application, a confirmation of the mobile phone number is required.

Differences from analogues

Google Duo is distinguished from other similar solutions not only by its strict asceticism, but also by one amusing and rather unusual function. This feature is called "Knock knock" and it consists in the fact that you can see the interlocutor via video communication even before picking up the phone. However, for this, Knock-Knock must be activated for both interlocutors.

About the interface

Google Duo has a very concise interface. In view of this, the application can be advised to all lovers of minimalism, as well as to those who want to call up with loved ones via video communication, but do not really get along with modern "smart" devices. Among the settings that you will find in the corresponding menu, the inclusion of vibration on a call, the inclusion of the "Knock" mode and limiting consumption mobile traffic.

Google has released a new video calling service, Duo, which should be a great alternative to existing apps. How did the developers decide to distinguish themselves when creating the program? Not at all an exciting interface or a large set of functions, on the contrary - Duo is positioned as simple and easy to understand for any user.

Google has developed a new simple and convenient service for video calls Google Duo

The new product attracts attention with a number of other features concerning both the content and the very use of the program. We will take a closer look at what Google Duo iOS and Android are, how to install and use the service.

How can Google Duo attract users?

The concept of the utility is simple - the developers set themselves the goal of creating the most convenient service for video calls that will work on platforms and provide excellent quality of communication and video transmission.

So, the idea itself is attractive in that the application can be easily mastered not only by an ordinary teenager or an adult, but also by older people or, conversely, small children - if necessary, call their parents.

Therefore, Google Duo, which was released in May 2016, has an uncomplicated interface and allows you to make a call with two clicks. This cannot be offered by other competitors of the service.

To download the application, you do not need to have or mail, your record is only attached via mobile number... That is, there is no need for a long process of registering a new user.

This is also where the peculiarity of the program is manifested - it is available only on smartphones, and at the same time you can use account on only one device.

Another positive feature of the service is its adaptation to the Internet on Android and iOS. He can switch from Wi-Fi connections if it is weak, additionally use forces mobile internet... In general, the application takes into account both connections and tries to provide a high-quality connection as much as possible.

If there are not enough resources for excellent video quality and voice data transmission, the application will lower the image resolution, as a last resort, it will offer to turn off the camera. The same will happen if running out. With all this voice communication will not go anywhere, the call will not end - here the feature of the competitor Skype immediately comes to mind, which practically does not work with a weak connection.

Now let's move on directly to how to use Google Duo apk, along the way we will consider other advantages and features of the application.

Google Duo at work

Registration for Android or iOS is performed as follows:

• At the first start, you need to go through a short registration - indicate the country and mobile number;
• After that, you will be sent a message to your phone with a code that must be entered in the program to confirm registration;
• Next, confirm four dialog boxes- requests to use audio, video with photos, access to contacts, the ability to send messages. Naturally, allowing the use of a particular function is a matter of your personal desire. But confirming the above requests will allow you to have access to all capabilities of Google Duo;
• Note that the request for access to contacts and sending messages is only needed to find registered accounts and the ability to invite new people to the service.

That's all. As they say, all ingenious is simple.

You can now start using the application. It goes like this:

• The main menu of the program will appear in front of you - your image, the call key and three dots in upper corner to enter the settings;
• When you press the call key, you get to the phone book, where contacts are collected. First of all, users who have Google Duo on iOS or Android are displayed, then - all other numbers to whom you can send a message with an invitation to the application;
• To make a call, you need to press the call key and select a contact from the list. If you want, during the call, you can turn off the video, leave only the voice connection.

Settings and interesting features of the service

Google Duo has the following settings:

• "Knock Knock" - we will dwell on it separately;
• The ability to activate vibration during a call;
• The function of limiting mobile traffic - useful if you, for example, have an expensive Internet;
• A line with your phone number, the ability to remove or replace it if you have lost or installed a new SIM card;
• Blocked numbers are an analogue of the "Black List".

What is the Knock Knock function?

If you are in the contact list of the user you are calling, then he will see the video from your camera even before he picks up the phone. This is a very interesting feature that can be a lot of fun to use.

True, it does not work on iOS devices due to the peculiarities of the system itself - it does not give permission for such actions as displaying video before picking up the phone. Perhaps, over time, this problem will be resolved on the platform.

Note that if you wish, you can always turn it off, and if the call is made from a stranger, you will not see his image. You will only see videos of your friends. This function was promoted by Google as one of the most interesting in the application, and, indeed, it cannot yet be offered by competitors among similar services.

So, Google Duo for iOS and Android is.
