As concerns over data privacy and security grow, encrypted messaging apps have become a go-to choice for many. Among those, Threema and Signal stand out as two of the most popular options.
Both apps promise top-notch security and privacy measures to protect your data and communication. But how do they compare, and which one should you choose? Let’s compare both apps, comparing their features, privacy, security, usability, and pricing so that you can make an informed decision.
What Is Threema?
Threema was developed in Switzerland, a country known for its strict privacy laws. The app was launched in 2012 by Threema GmbH and has since grown into one of the most trusted secure messaging apps available.
Threema's primary focus is on data restraint, meaning it collects as little data as possible. It also doesn't require a phone number or email address to create an account, allowing you to use the app with complete anonymity.
Plus, Threema offers end-to-end encryption on all types of messages, including text messages, voice calls, and even file transfers. This encryption ensures that only the intended recipient can read your messages — not even Threema has access to them.
What sets Threema apart is its unique set of features. For instance, it offers group polls, a feature not commonly found in other secure messaging apps. Plus, Threema provides a contact synchronization option that helps users find other Threema users from their contact list. Of course, this feature might pose some concerns for those looking for a completely anonymous messaging experience.
In terms of privacy, Threema operates under strict Swiss data protection laws and doesn't log IP addresses or metadata. Its servers are also located in Switzerland, offering an extra level of security.
What Is Signal?
Signal is a free, open-source messaging app known for its strong encryption protocols. Developed by the Signal Foundation and Signal Messenger, it was introduced in 2014 and has since become a favorite among those who prioritize their online security. Signal is also funded by donations and grants, which means it doesn't rely on selling user data for revenue.
Signal provides end-to-end encryption for every message and call, making sure that only the sender and the receiver can access them. It also uses the Signal Protocol, which is widely regarded as the gold standard for secure communication. This protocol combines the Double Ratchet algorithm, prekeys, and a three-DH (Diffie-Hellman) handshake to offer robust security.
Signal's features include text messages, voice and video calls, group chats, and the ability to send files and pictures. And, of course, all of these features are protected by the same strong encryption. It also offers disappearing messages that automatically delete after a set period and a screen security feature that prevents screenshots.
As for privacy, Signal collects minimal data, only storing the date of account creation and last connection time. It doesn't store your contacts, social graph, conversation list, location, or user avatar. It also operates under US jurisdiction, and the transparency of its open-source code provides an extra layer of trust.
Threema vs. Signal
Both Threema and Signal offer end-to-end encryption for all forms of communication, ensuring that only the sender and receiver can access the content. They also prioritize data minimization, collecting as little data as possible. Plus, both apps offer features like group chats, file sharing, and voice and video calls.
However, there are also significant differences. Threema requires a one-time fee, while Signal is free to use. Threema also doesn't require a phone number or email for registration, offering total anonymity, whereas Signal does require a phone number.
Another difference lies in their legal jurisdictions and operational models. Threema operates under Swiss laws, while Signal falls under US jurisdiction. Threema's servers are located in Switzerland, which is known for its strict privacy laws, while Signal's operational details are open-source.
The two apps are also different in their additional features. Threema offers group polls and contact synchronization, while Signal provides disappearing messages and screen security.
Which Is Best for Privacy?
While both apps offer high levels of privacy and security, Threema's ability to be used anonymously and its strict adherence to Swiss privacy laws might appeal to those seeking the highest level of privacy. However, Signal's transparency through its open-source code and strong encryption also make it a popular choice.
Some users might be concerned about using Signal because it requires a phone number to create an account. However, there are ways to use Signal without divulging your personal phone number.
To use Signal without providing your phone number, simply download Burner and create an account. Our subscription service allows you access to up to three different temporary phone numbers, none of which can be traced to your personal information.
Ultimately, the choice comes down to what you’re comfortable with and what privacy features you’re looking for.
Which Is Best for Usability?
While it might not be the first feature that comes to mind, user experience is an important factor in choosing a messaging app. Threema offers a clean, intuitive interface with features designed to make the user experience seamless and simple. However, while valuable for privacy-conscious users, Threema’s added features can make it seem slightly more complex, especially for those new to secure messaging.
However, Signal also boasts a straightforward and intuitive interface. The app closely resembles mainstream messaging platforms, helping to smooth the transition to encrypted communication. Plus, the desktop version syncs seamlessly with the mobile app, ensuring a seamless user experience.
While both apps offer a user-friendly experience, the choice between Threema and Signal may come down to your personal preference and which specific features you value most.
Which Is Best for Pricing?
When considering which secure messaging app is best for you, pricing is another important factor to consider. Threema and Signal both take different approaches to pricing.
For instance, Threema operates on a one-time fee model. Users pay a small fee to download the app, and this includes all future updates.
There aren’t any subscription fees or in-app purchases, making it a cost-effective option for those willing to pay an upfront cost for privacy. This one-time fee also helps support the development and maintenance of the app, as Threema doesn’t sell ads or user data.
On the other hand, Signal is free to use. It operates on donations and grants, which means it doesn't rely on selling ads or user data for revenue. This funding model helps make sure that Signal can continue its commitment to privacy and security.
While Threema's one-time fee might be a concern for some, it's a small price to pay for the level of privacy and security the app provides. However, Signal's free-to-use model is undoubtedly appealing, especially to those who are new to secure messaging apps and want to try one out without any financial commitment.
So, Which One Is Best Overall?
Choosing between Threema and Signal ultimately comes down to your individual needs and preferences. If maximum privacy is your priority and you don't mind paying a one-time fee, Threema's strict data restraint policy and Swiss jurisdiction might appeal to you. Its unique features, like group polls and contact synchronization, can also make it more accessible.
On the other hand, if you prefer a free, open-source messaging app with high-level encryption protocols, Signal is an excellent choice. Its disappearing messages and screen security features add extra layers of security to your conversations. Plus, Signal's transparency through its open-source code can add an extra layer of trust.
Ultimately, the best app for you depends on what you’re looking for and how much you’re willing to invest in your experience.
