Signal App Review: A Private Messenger to Consider in 2024

The first thing that most people do when they get a new smartphone is install essential apps. For the majority of those people, Instagram and Facebook are most likely the first two apps they install, closely followed by a direct or private messaging app.

But which private messaging app do you install? The choice for most people used to be obvious: WhatsApp. However, due to privacy concerns, people have been starting to shift away from WhatsApp and toward alternative private messaging apps, with Signal being one of the top choices.

Signal is a free, secure, and open-source messaging application that uses end-to-end encryption technology to help you securely communicate with other Signal users. Because Signal Private Messenger uses end-to-end encryption for all communication, it has become the top recommendation for and by people who care about the privacy and security of their online communication.

In this Signal app review, we will take a look at what has made this messenger so popular and show you whether it’s as safe as it claims to be.

About Signal Private Messenger

Signal app

Signal Messenger is a secure messaging service for desktop, iOS, and Android. You can think of Signal as a more private alternative to WhatsApp, Facebook Messenger, Telegram, iMessage, and even SMS and MMS. It uses the internet and its technology to send messages, both for group chats and one-on-one communication.

Those messages can include images, videos, files, and voice notes. Signal can be used to make voice and video calls, both group and one-on-one.

Signal isn’t owned by a big tech company. Instead, Signal is built by a 501c3 nonprofit foundation. Unlike Facebook, which owns WhatsApp, the owners of Signal aren’t trying to make money. What’s more, Signal isn’t gathering a bunch of data on you to show you more tailored advertisements or any advertisements at all.

Signal was launched back in 2014, and it has become more widely adopted in 2019 and 2020. As of the last quarter of 2023, Signal has been downloaded around 3.77 million times. The Signal messaging app has approximately 40 million monthly active users. Signal has been installed on more than 50 million Android devices, making it one of the most popular encrypted text apps.

Installation and Setup

Installing and setting up Signal is very easy. All you need to do is download it from the Play Store or App Store, verify your phone number, set up your username, and create a PIN.

Even though Signal uses your phone number to identify you, that doesn’t mean that it’s not private. What makes it unique is a type of encryption, called the Signal Protocol.

Once you have installed the mobile app, you’re ready to start using it. You can start a conversation with your Signal contacts from within the app. Your Signal contacts are people that you have in your contacts list whose phone number is associated with a Signal account. Contacting them is seamless. If they are on Signal, you’ll be able to get in touch.

If you want to use Signal on your desktop, you can download the app from Signal’s website. The Signal desktop app is available on Windows, Mac, and Linux. The desktop app will sync messages from your phone to your computer. Installing and using Signal on your desktop is optional. You’ll get the same full experience on your mobile device.

User Interface

The user experience of Signal is similar to the likes of WhatsApp, Facebook Messenger, and the majority of other popular chat apps. At its core, Signal is easy to use and allows you to talk one-to-one and in groups, send stickers, files, photos, voice messages, and make video calls.

Signal’s user interface incorporates features such as inviting empty states to boost user interaction, handy navigation tips, and straightforward prompts during onboarding to efficiently assist users in configuring the app.

How and Why the Signal Messaging App Is So Secure

How and Why Signal is so secure

All communication that happens on Signal (this includes all one-to-one and group messages, transfers of photos, videos, files, all voice calls, and video calls) is end-to-end encrypted. There’s no third-party access to your data and conversations because encryption happens between two or more individual devices using Signal.

This basically means that the company behind Signal cannot read your messages, even if they want to.

Yes, some other messaging apps also offer encrypted messaging as a feature. However, everything on Signal is encrypted from the very start and by default. In addition, Signal has other privacy-specific features, such as self-destructing (disappearing) messages that will automatically delete themselves after a period of time you choose.

Many messenger companies collect a lot of data about you. On the other hand, Signal tries not to. Based on our research, the only thing that Signal knows about you is your account’s phone number, when you were connected to Signal last time, and when you created your Signal account. The rest of your data and messaging are unknown to Signal.

Everything in your Signal app—all your messages, files, pictures, videos, etc.—is stored securely and locally on your phone. If you want to switch devices, you can manually transfer your data. When you compare that to other desktop, iPhone, and Android apps that can reveal your full name, all your messages, a list of exactly where you have accessed your account from, and more, it’s easy to see why Signal has become so popular.

Is Signal So Popular?

Signal is so popular

The main reason why so many people have started using Signal is that they are concerned about their privacy.

Signal has been endorsed by big-time tech names such as Tesla/SpaceX’s Elon Musk and Twitter’s Jack Dorsey. Occasionally, Signal has landed the top spot on the Google Play Store and Apple App Store’s top free apps chart. It has been praised by many privacy advocates and all types of business activities and niches, including Edward Snowden, who endorsed Signal back in 2015.

The current spike in popularity of Signal has happened thanks to the revamp of WhatsApp’s privacy policy, which allows WhatsApp to share even more data with Facebook. Many people want to move their conversations off Facebook, and this is where Signal steps in.
