Signal vs Viber in our news:

2022. Messaging app Viber launches Payments - a new digital wallet



Viber, the messaging app owned by Japanese e-commerce giant Rakuten, is launching Payments on Viber — a new service that will let users set up digital wallets tied to their Viber accounts. Linked to other bank accounts as well as Visa and Mastercard, Payments wallets can in turn be used to make bill payments and buy goods, as well as transfer money to other individuals. Peer-to-peer transfers will be the first of these services to launch, and these will be free. Services like payments to businesses likely will have some fees attached. The service is being launched first in two markets — Germany and Greece — with the plan being to extend that to the rest of Europe, and then Viber’s wider global footprint of 180 countries, this year and next.


2021. Signal expands encrypted group video calls to 40 people



Messaging app Signal can now support group video chats with 40 participants — up from five — and end-to-end encryption will still be intact. End-to-end encryption means only the participants in the call can view the messages or video. No one, including the messaging provider, government authorities, or hackers, can view the calls, unless a participant accepts them into the video session or they snatch your device.


2020. Signal adds encrypted group video calls



Signal, the free and open source encrypted messaging app, launched end-to-end encrypted group video calls. The feature, which at present is limited to five people per call, allows members of a Signal group to pop in and out of an ongoing call at will. Notably, unlike Facebook's Messenger Rooms, group video calls on Signal are end-to-end encrypted. In an existing Signal group, you only need to tap the video icon in the upper-right corner of the screen to start the call. Once you've done so, group members can join or leave the call at their pleasure.


2020. Viber launches group video calls for 20 users


Viber becomes the latest platform for launch a Group Video Calls feature, enabling large meetings and online classes. The new feature will enable group video calls of up to 20 people with unlimited duration. Viber already has a lot of success with Group Audio Calls (up to 20 people), and group chats (up to 250 people) so in light of the current situation, Viber has also started to add video to its capabilities. Group Video Calls show the speaker to all participants but users can also choose to pin any video to their screen during the call – their own or other participant’s video. Users can also mute themselves, or disable video during the call, as well as see if other participants are on mute or their video is turned off.


2017. Viber acquired shopping keyboard startup Chatter Commerce



Messaging app Viber earlier this year made its first foray into shopping services with Instant Shopping, a feature that lets you search for items for sale via a keyboard when you have the messaging app open. Today, the company has acquired Chatter Commerce, the startup that helped build that feature. That's how Viber wants to catch up with alternatives. According to rumors, Amazon is building a consumer-focused messaging app. With Facebook also adding in more transactional features into Messenger — part of a huge expansion that has taken it beyond basic chat and into bots and other services — there is a clear trend among messaging apps to leverage engagement they already have with their users to drive their business in other ways.


2017. Viber introduced secret chats with self-destructing messages



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. Viber adds e-commerce feature



Messaging app Viber (owned by e-commerce company Rakuten) wants to monetize on e-commerce without turning to stupid advertising. Viber will start to present users with items for sale, inspired by your current chat, when you press a small shopping bag icon at the bottom of the screen and search for items.  The feature is due to go live in the U.S. first, on March 6, before Viber looks to roll it out to other markets. Initially the shopping feature will not be letting users make purchases directly on Viber itself — they will either be redirected to the relevant page in a brand’s app via a deeplink.


2017. Encrypted messenger Signal adds voice and video calling



A new beta version of Signal, the encrypted chat application, has enabled voice and video calling. According to the app’s changelog, beta users are able to try the new feature with others who also have the setting enabled. Though aimed at the privacy-minded, Signal competes more broadly with apps like Facebook Messenger, WhatsApp and Google Duo, all of which support video calling. These features are now considered table stakes for those entering the messaging app space with their own alternative clients. Signal may be catching up with the rest of the market, in terms of feature set, but the app struggles with adoption because it lacks the network effects of other, more social apps. This, of course, is by design. Because of its security and privacy focus, Signal doesn’t pull in your contacts from other social networks, upload your address book, or offer fun tools like Snapchat’s Snapcodes to make adding new friends easier.


2016. Viber launched Public Accounts for businesses



Messaging app Viber is launching Public Accounts for businesses and brands who want to communicate with Viber users for marketing, customer service - or a bit of both, without a user needing to add that account as a contact first. Instead they can justsubscribe to them. Besides, by the end of November, Viber’s API will be integrated with between 10 and 15 popular CRM packages for customer service integration. Businesses can then send and read their Viber messages alongside all of their other social media, email and messaging interactions. Public Accounts puts Viber among several other consumer-focused messaging apps that already  have similar feature: WeChat, Line and Facebook Messenger.


2016. Viber adds end-to-end encryption and hidden chats



Following WhatsApp, another popular messaging app Viber is introducing end-to-end encryption for all messages and calls on its platform, including group chats (you can chat with up to 200 people), and a way to ‘hide’ chats on your account alongside its existing expanded deleting function. The new privacy features will work across Android, iOS, PCs and Mac desktops, with the encryption coming with the latest app update (6.0) and a reauthentication of the app (via QR Code) to turn the feature on. Viber’s encryption will come with varying levels of security, which will show up in the form of a color-coded lock on the right side of the screen.
