How to Make a Secure Messaging App Like Signal? 

In the second quarter of 2023, mobile messaging app Signal registered almost 3.74 million downloads worldwide. Today, there’s a growing need for safe and secure ways of communication and apps like Signal are in high demand. In this article, we’ll talk about features that are necessary to build such an app and how much it would cost you. 

What’s a Secure Instant Messenger? 

Having a secure instant messenger implies that the messaging platform prioritizes user privacy and employs robust security measures to protect digital communications. Key features of a secure instant messenger often include end-to-end encryption, which ensures that only the intended recipients can access the messages, safeguarding them from unauthorized interception or surveillance. 

Additionally, secure instant messengers may incorporate features like self-destructing messages and stringent user authentication methods to enhance overall privacy and prevent unauthorized access to sensitive information. The primary goal is to create a trusted and confidential environment for users to communicate without the risk of their messages being compromised or accessed by unintended parties.

Features of an Encrypted Messaging App

While each messaging app has a different set of features, there are some key features that are significant to include in every app. Here’s a short review of these features: 


An encrypted messaging app begins with a secure sign-up and log-in process. Users create accounts with robust authentication methods, such as two-factor authentication or biometric recognition, ensuring only authorized individuals gain access. This initial step establishes a foundation of trust and confidentiality, safeguarding user data from unauthorized access or potential breaches.

Personal/Group Chat

The core functionality of an encrypted messaging app revolves around personal and group chats that prioritize user privacy. End-to-end encryption ensures that only the intended recipients can decipher the messages, preventing any interception or eavesdropping. Whether engaging in one-on-one conversations or group discussions, users can communicate freely and securely, knowing their messages are protected from external scrutiny.

One-Time Viewable Messages

To enhance privacy, the app can incorporate the feature of one-time viewable messages. Users can send sensitive information or images that are only accessible for a single viewing by the recipient. Once viewed, the content becomes inaccessible, adding an extra layer of security and mitigating the risk of unauthorized access or unintended sharing. This feature ensures that confidential information remains confidential, even if the recipient’s device is compromised.

Self-Destructing Messages

For ephemeral communication, the self-destructing messages feature allows users to set a timer for how long their messages remain visible. After the specified duration, the message automatically disappears from the sender’s and recipient’s devices, minimizing the chances of sensitive information being stored or shared beyond its intended timeframe. This feature is particularly useful for sharing temporary information that requires a higher level of discretion and confidentiality.

Cost to Make a Secure Messaging App

The cost to develop a secure messaging app can vary based on several factors, including the complexity of features, platform compatibility, design requirements, and the level of security measures implemented. 

A basic secure messaging app with standard encryption protocols may range from $50,000 to $150,000. However, more advanced features like end-to-end encryption, self-destructing messages, and robust user authentication can increase development costs, potentially reaching $200,000 or more. 

Additional expenses may include ongoing maintenance, server hosting, and updates to address emerging security threats. Engaging experienced developers, adhering to industry standards, and prioritizing robust security measures contribute to a higher upfront cost but are crucial for ensuring the app’s reliability and user trust.
