How Signal App become popular

Over the past few days, it became the number one free app within the iOS App Store and therefore the Google Play Store, largely due to three things entirely out of its control. the primary was the move by both Facebook and Twitter to dam President Trump from their platforms, which drove many of his supporters to seem for alternatives.

Finally, WhatsApp updated its privacy policy earlier in the week and required users to simply accept that it shares some information with Facebook before continuing to use the app. The confusion around the change and therefore the mishandling of the rollout caused people to stress it had been just another Facebook data grab. Elon Musk tweeted to “Use Signal App” to all his followers.

Cross-platform messaging app Signal App that garnered many new users within days of WhatsApp’s new policy faced a worldwide outage on Friday. The corporate said that it had been experiencing technical difficulties which it had been ‘working hard to revive services as soon as possible’.

Signal App that piqued user interest after Elon Musk’s clarion call to “Use Signal App” has said that it’s been adding new servers and additional capacity at a record pace every single day in the week. “But today exceeded even our most optimistic projections. Millions upon many new users are sending a message that privacy matters. We appreciate your patience,” the messaging app tweeted.

In India, Signal App has been downloaded on the brink of 3 million times.

WhatsApp remains the foremost popular messaging app, with over 2 billion monthly users, despite its recent privacy policy mess. Signal App, on the opposite hand, had around 20 million app installations at the top of last year, consistent with App Annie, an app analytics platform.

Signal App was co-founded by Brian Acton.

Signal App is different, not simply because it’s fancy cryptography protecting your conversations, but because it had been found out from the start to vary. the corporate doesn’t show ads. It doesn’t sell your information. It doesn’t even charge money

On its website, WhatsApp recently revealed an update to its Terms of Service, including one very notable change that essentially removed the choice for users to stop their personal information from being shared with parent company Facebook.

This particular change comes into effect on February 8, 2021 (now rescheduled to May 15, 2021).

Both these services are direct competitors to WhatsApp, and both are labelled as possibly safer and more ethical in their approach to handling user data. Signal App, especially , has received many traction as an alternate because of a recent tweet by Tesla CEO Elon Musk that suggested for people to start out using it rather than WhatsApp.

Signal App Features:

Signal App has all the essential features for direct messaging enabled, including the choice to send media, contacts, and site, although file size limits vary depending upon what you’re sending. Photos are covered at 6MB, while video, audio, and documents are covered at 100MB.

  • It has a disappearing chat feature that permits messages to disappear any time between five seconds to seven days, and it’s the choice to send a one-time viewable image that disappears after the recipient views it once.
  • Signal App allows for discussion groups of up to 1,000 participants, with voice and video calling up to 5 people allowed.
  • It cannot be used on a browser but does have dedicated clients for desktop.
  • Signal App allows only local backups and doesn’t backup content on the cloud.
  • There is a feature on Signal App called “Note to Self” which allows users to basically chat with themselves, and use it considerably sort of a personal notepad.
  • There is also an incognito mode for the keyboard, and therefore the ability to delete old messages quickly.

While it doesn’t have as many customization options like its rivals (such as stickers and wallpapers), Signal App’s developers aim to introduce a number of these within the near future.


Signal App’s security measures are deemed the simplest out of the three, and for an honest reason.

For starters, it uses the highly-rated Signal App Protocol to perform E2E encryption for each single message and call that passes through its servers.

Additionally, it also encrypts message metadata – something WhatsApp has did not do – which basically means absolutely no information regarding a message (including time and place sent) are often intercepted externally.

There is also the choice to dam recipients from taking screenshots of a message, and also a feature to permit faces on photos to be blurred before they’re sent.

Goodbye Facebook—but who is behind Signal App and Telegram?

In its early years, the messenger became famous because of the platform of choice for dissidents and protesters and, unfortunately, for criminals and extremists, all looking to stay their communications out of the reach of the authorities. Despite its lack of end-to-end encryption by default and therefore the fact it holds decryption keys, Telegram says that to access messages it needs keys from different jurisdictions to frustrate any attempts by enforcement to access the content. this provides an honest insight into the first philosophy behind Telegram.

Until 2018, the Signal App was fairly niche and unless you worked in some sort of security field, it had been unlikely to be found on your phone. on the other hand, Brian Acton, one of WhatsApp’s founders, left Facebook and plowed $50 million into Signal App to assist take it mainstream.

Are Signal App and Telegram  better than Whats App?

Yes… and No. It’s undoubtedly true that Facebook’s specialize in data collection and processing is at odds with the principles of secure, private messaging. More worryingly, Facebook’s long-term plans also involve the eventual integration of WhatsApp’s underlying platform with Facebook Messenger and Instagram—this isn’t excellent news for WhatsApp users

The NY Times reported that since the announcement of the privacy update many users and a few media outlets interpreted the notification as a marked shift in WhatsApp’s data-sharing practices, mistakenly believing that the corporate could now read people’s conversations and other personal data. The concerns resulted in people switching to other messaging services like Signal App and Telegram. This week, Signal App became the No. 1 app in India, one among WhatsApp’s biggest markets, on Apple and Android phones, the NYT said.
