The two words were Use Signal. And the messaging platform lurking in the shadows of WhatsApp suddenly came strongly to the forefront. Its encrypted messaging feature got people’s attention in no time.
The result of the tweet was two-fold – on one hand, the user base of the Signal messaging app increased to a massive level and its downloads climbed up by 4200%, on the other hand, how to create app like Signal became the new inspiration for entrepreneurs looking to enter the heavily profitable domain.

Before we get into the features and Signal app development cost elements, let us first look into the WhatsApp announcement that led to the sudden peak in the Signal registrations.
What Was the WhatsApp Announcement About?
WhatsApp told its users on January 6th that they will have to agree to let Facebook and its subsidiaries collect WhatsApp data – including location and phone numbers before Feb 8 or they might have to lose access to the application.
A Sensor Tower representative said, “From January 6 to January 10, Signal saw approximately 7.5 million installs globally from across the App Store and Google Play,”.
WhatsApp has since then been taking measures to reinstate that the move will not leave users’ chats unprotected. They also clarified that the effect will only be seen by users outside the EU and UK.
What Are the Must-Have Features for Signal Like Application?
There are a number of features that contribute to the process when you build a chat app like Signal. While 80% of them are the same as any messaging platform, there are a few elements that make Signal special as every social networking app development companies would tell you.
Let us look into what they are.
1. Invite friends
The option to invite friends and start a new group is the first thing that users see when they open the Signal social media app. The invite friends option, which we consider a must-have functionality asks users to give the app access to their contact book.
2. Real-time messaging
At the core of the Signal app features lies the functionality of real-time messaging. Signal enables users to interact with each other from around the world in real-time, without any evident concurrency issues.
3. Sharing features
Signal private messenger app makes the sharing process easier for the users by giving them the option of sharing documents, contacts, media (images, videos, and GIFs), and location with their contacts or in a group.
4. Video and in-app call
Calls have become a must-have feature of today’s messaging platforms. While once limited to text messaging, today users are demanding the facility to make video and in-app calls to their contacts.
Devising a strategic push notification strategy is not difficult for the messaging apps domain. The application only has to show messages, call and missed call prompt, and when it’s time to back up the data. Signal, however, gives users the option to turn off lock screen notifications on their devices.
6. Privacy settings
The Signal chat app comes backed with a series of privacy settings like screen lock, incognito keyboard, etc. Following WhatsApp’s failure to give users a guarantee that their data will be secured, privacy settings like these are poised to become a must-have element of answers around how to create app like Signal.
7. End to end encryption
End to end encryption is one of the top ways to secure a mobile app. The open-source end to end encryption feature of Signal private messenger app makes it impossible for telecom companies, advertisers (Signal doesn’t allow advertisements in the app), and even Signal to read users’ chats or view their activity.
While these are some of the must-have features for Signal secure messaging like application development, there are a number of other features that are native to Signal but absent in other messaging apps. Some of those are Disappearing messages, Safety binary numbers that one can cross-check with their contact’s to ensure that there’s a complete end to end encryption, group chat with 8 users, and voice record functionality.
The privacy and security of Signal are one of its key selling points and also one of the prime elements of Signal like app development cost. So in order to know how much does it cost to build a messaging app like Signal, it is first important to know what makes it truly secure.
How Does Signal Encryption Works?
The uncontested reputation of Signal privacy backed by high-profile users like Edward Snowden and Brian Action is something that is leading the onset of a new movement – one where users’ chats are kept truly private and encrypted.
Here’s how the most secure messaging app of 2021 works.
With most encryption systems, when an application is installed in a phone, a permanent key pair is created. The pair is then used for encrypting and decrypting messages: one ‘public’ key is sent to the messaging server and is used to identify users, and the ‘private’ key never leaves users’ phones.
If the private key gets compromised, messages become prone to decryption and misuse.
The protocol that Signal uses changes the key after every message by generating multiple temporary key pairs for users in addition to their permanent keys. When a user sends a message over Signal, the application merges the permanent and temporary pairs of private and public keys for both the users and creates a shared secret key which is used for encrypting and decrypting the message.
Since the generation of the secret key needs access to the users’ private keys, it lives only on their devices. And Signal’s protocol system of the temporary keys – where it constantly replenishes keys for every user – enables the app to get new shared keys after every message.
Besides the encryption protocol, there are a number of other things that make Signal fairly unhackable –
- Lock screen notification off function
- Disappearing messages
- Encrypted calls
- Blurred photos
Now that we have looked into the features and the encryption system that makes up for Signal like app development cost, the next step will be to break down the components that a social media app development company will give you as Signal app development cost estimate.
How Much Does It Cost To Build A Messaging App Like Signal?
The Signal app development cost range is dependent on a number of factors. Like every mobile app development cost estimate, four key factors contribute to the overall price quote.
- Mobile app design
- Team size
- Location of the agency.
When we talk about Signal specifically, imitating the same feature set will prove to be on a higher side. So what we recommend is to create a messaging app MVP and add the encryption protocol in it. This way, you will be able to test the waters before launching a full-fledged application.
Our social media app developers advise that entrepreneurs must first create a plan of features that they would like to have in the application. On the basis of the features, we can drill down on the technological and resource capabilities, which in turn would decide the social media app development cost.
Now that we have reached the end of the piece, let us throw some light on how you can earn money at the back of your Signal like application.
How Can You Earn Money From Your Signal-like Application?
It is extremely difficult to answer how Signal makes money because it doesn’t. It is a non-profit business meaning they stay afloat from government funds and donations. While this is a noble stance, it can make it difficult for entrepreneurs to enter the space.
But then with in-app advertisement out of the picture, since that is what raised havoc on Facebook in the first place, what other options do entrepreneurs have?
An option that you can explore is extending your brand to enterprise users. You can create a version specifically looking into business communication needs with features like third-party integrations and on-premise deployment.
The key to whichever way you finalize to make money from your app, ensure that it doesn’t go against the moral value of the application. It should not put users in an if this then that situation. You should have a workaround to give users the same experience whether or whether not they share their data.
The creation of a Signal-like app is in many ways different from building any other messaging platform, both on a business and ethical level. You will have to ensure that the application respects people’s privacy and that there is no loophole for data to flow out from.
