Threema vs Sign: Design & customization choices

Sign might very nicely be the moment messenger that Edward Snowden recommends in terms of utilizing a safe WhatsApp various. Nonetheless, the Sign Basis has been paying an increasing number of consideration to creating Sign right into a full-fledged instantaneous messenger not too long ago, each when it comes to performance and visuals, whereas conserving tabs on safety, after all.

For those who check out the chat, you might have stickers and GIFs which have been made accessible along with the standard slew of emojis to make your messages much more private.

Sign permits you to select between a light-weight and a darkish theme, with a selection of language, in addition to as much as 4 completely different font sizes.

A light-weight and a darkish theme can be accessible in Threema. As well as, you may select from three font sizes and 15 languages within the settings. Nevertheless, the backgrounds and look are extra spartan on the whole. You’ll be able to decide any picture from the gallery, in any other case you find yourself with solely the selection of a Threema background or having no background in any respect. As well as, there are presently no shade choices in terms of the chat look or the potential for customizing the chat bubbles.

Those that love colourful and different chat home windows will certainly be happier with Sign than with the moment messenger from Switzerland. Threema is useful however it’s not the final word revelation for these of you who like to customise apps primarily based to your visible preferences proper right down to the smallest element.

Threema vs Sign: Platform help

Okay, there wasn’t that a lot going for Threema when it comes to visuals, however what in regards to the variety of platforms supported? Certain, the apps can be found for each iOS and Android, with Sign being free to obtain whereas Threema requiring you to fork out $2.99. We’ll discuss extra about that later.

It’s also possible to get hold of Threema from Huawei’s AppGallery, and if you happen to choose, you can too land the app from the Threema store, the place it is likely to be cheaper for you by a number of cents (depends upon the place you reside). Android customers who’re unable to entry Google Play have undoubtedly taken Threema into consideration as an instantaneous messaging various. For those who like, you can too use Threema Web within the browser.

As with WhatsApp, all you want to do is to scan a QR code to attach your smartphone to your laptop. If in case you have set a password earlier than scanning, you do not have to re-scan the QR code each time you need to use it. It’s good to know that every part is encrypted from end-to-end.

Threema additionally provides Threema Work, an instantaneous messenger service meant for firms, alongside Threema Training, which is an excellent instance for instructional establishments. Corporations with even increased safety necessities can even run the messenger on their very own firm servers because of the self-hosting choice Threema OnPrem. Sign will also be used on the pc however not within the browser. As a substitute, you’ll have to set up Signal for the desktop the place it’s accessible for Home windows, Mac and Linux.

Sign could be operated concurrently on as much as 5 gadgets. Threema doesn’t but provide this multi-device choice, because it says that that is troublesome to implement on account of knowledge safety and safety points. Nevertheless, they’re engaged on it and there’s a probability of this characteristic being provided sooner or later.

I’d additionally wish to see a desktop utility for Threema, however on the whole I really feel that the moment messenger from Switzerland has the sting over Sign in terms of platform availability, particularly with the enterprise choices like Threema Work.

Threema vs Sign: Features

In each instantaneous messenger comparability, I all the time ask myself simply how essential the person features are within the first place, if we discover them in each chat service anyway. It doesn’t matter whether or not it’s the chat home windows themselves, group options, the choice to ship media and knowledge on the whole or video and voice calls: Such options are nearly ubiquitous, so it is price peering into the main points that differentiate such options from each other.

Particular person or group chats

The lynchpin of any instantaneous messaging app can be the chat view, the window wherein you talk along with your contact or group. We now have already talked about the truth that Sign permits you to use stickers and GIFs, along with Reactions that add an identical emoji to each message.

Threema usually comes throughout as extra spartan, as there are neither GIFs (for privateness causes) nor stickers. On the very least, there are many emojis to play with. Additionally, you may approve or disapprove every particular person message by briefly urgent down on the message after which giving it a corresponding thumbs up or thumbs down on the prime.

With Threema you may ship recordsdata which can be no bigger than 50MB in dimension, whereas Sign provides double the file capability. It’s also possible to ship places and contacts with each apps. In order for you, you may pin chats with Threema in addition to in Sign. What’s unique to Threema is that this, you can too create polls very simply. The latter is unavailable with Sign, however you profit from disappearing messages.

Okay, you can too delete messages in Threema, however this selection is buried deep throughout the settings beneath the storage administration menu. You’ll solely have the choice to delete something that’s older than per week, a month, 3 months, 6 months, a 12 months, and as much as two years for the time being. Therefore, it’s merely a delete perform and never a predetermined timeframe for computerized deletion.

One other good chat characteristic which is simply accessible on Threema (albeit just for Android for the time being) is personal chats: Personal chats, now what’s that every one about? This perform will allow you to defend chats and conceal them within the chat overview if you want. Confidential content material is thus shielded from prying eyes. In relation to personal chats, solely the sender’s identify is displayed within the push notifications.

Each chat instruments additionally give you the chance to create teams. With Sign, these teams could be as giant as 1,000 individuals, whereas with Threema, the restrict stands at 256 pax. Sign even permits MMS teams with as much as ten individuals, however do keep in mind that these aren’t encrypted. In any other case, with each instantaneous messengers, the teams provide end-to-end encryption similar to in particular person chats.

Threema additionally provides a sensible characteristic in terms of group messages (an Android solely characteristic up to now): broadcast lists! Just like teams, you may create a listing of contacts whom you need to attain after which ship all of them a message in a single chat. For recipients of such broadcast checklist messages, it stays unknown to them that others too, have obtained the identical message.


For chatterboxes like me, voice messaging is the first characteristic that I am all for! Voice messages are logically discovered on each companies. With Sign, I’ve seen that generally voice messages get minimize off midway when you’re listening to it. Recording voice messages is strictly the identical with Sign as it’s with WhatsApp: Maintain down the document button that has the microphone icon, and also you’re good to go. After that, you may ship or faucet “Cancel”.

Threema handles voice messages barely in another way which in my view, is a wiser methodology. A easy faucet is sufficient to start voice recording, and also you even have the choice to pause a voice message which I discovered to be very handy. As soon as you might be carried out, you might have the choice to ship the recorded message to the digital trash can or to ship it to the supposed recipient.

Do I even have to say that each instantaneous messengers that declare to be equally safe, additionally ship encrypted voice messages? By the way in which, I discover the voice high quality to be very excessive with each apps, higher than its major competitor WhatsApp. In the meantime, you can too change the playback velocity between 0.5 instances and a couple of instances to fit your desire. By the way in which, each voice message in half velocity sounds as if it was recorded by somebody who continues to be in stupor.

Voice and video calls

For those who’re extra of an individual who prefers to speak to individuals straight as an alternative of sending them voice messages, you are most likely extra possible to make use of voice or video calls. Each can be found on Threema in addition to Sign, and each are also wholly encrypted as regular. Threema would not even require your telephone quantity, because the Threema ID is sufficient. Threema solely launched video calls as a characteristic final 12 months, whereas group calls stay out of attain. Sign provides group video calls that helps as much as eight individuals concurrently.

As a conclusion, we will mainly say that Sign provides greater than Threema in terms of options. Nevertheless, there are some very useful tricks conjured by Threema masters which make sure that buying the moment messenger could be a worthwhile effort for everyone, and never solely for individuals who depend on absolute safety.

Threema vs Sign: Encryption and knowledge safety

Let’s inform it like it’s: those that select Sign or Threema do not achieve this as a result of that is the place “everybody” is, so it is one of the best ways to achieve your contacts. Quite, we use these platforms as a result of they promise us extra safety than the moment messengers provided by Fb. Those that use Threema or Sign are additionally combating in opposition to a standard enemy, the place they every should persuade the plenty to modify. Each instantaneous messengers present many causes and incentives to take action, particularly within the areas of information safety, privateness, encryption, and anonymity.

Each get pleasure from a superb popularity for his or her security measures, however there are a number of tiny weaknesses that we’ve present in Sign:

  • It’s obligatory to offer your telephone quantity.
  • Sign is topic to the CLOUD Act of the USA and thus US authorities are entitled to entry knowledge saved inside.

Sign is backed by a basis, so every part is supported through donations. Which means that there is no such thing as a monetary incentive to promote knowledge, as a result of Sign doesn’t should churn a revenue. Threema doesn’t promote knowledge however its product as an alternative. Therefore, there is no such thing as a temptation for them to promote knowledge as nicely. 

As well as, IT specialists usually all the time give a thumbs up when discussing Sign and Threema: Every thing is end-to-end encrypted, whether or not particular person or group chats, video and voice calls, and even voice messages. One other nice characteristic is that this: contact lists, teams and consumer profiles are managed regionally in your gadgets and never on a central server.

With each, messages are instantly and irrevocably deleted from the server after supply, so there is no such thing as a server-side storage of the message historical past. With each instantaneous messengers, it is usually not essential to grant entry to the tackle e-book to be able to use the app absolutely with none restrictions. As well as, each Sign and Threema are open supply and provide customers the choice of verifying different contacts, like sending a QR code prior.

In relation to privateness, Threema is the winner!

So that you see, each companies are actually involved about our safety! Nevertheless, we discovered Threema to be much more constant than Sign and gained a number of extra factors the place Sign stumbled. As an illustration, Threema doesn’t require a telephone quantity or e mail tackle and can be utilized anonymously with out offering any private knowledge. After all, you may embody your tackle e-book if you happen to so choose, however Threema customers are likely to to not need to try this.

Threema depends by itself servers in Switzerland, whereas Sign makes use of US firms like Amazon and Google. So if you wish to use a service whose servers are positioned in Europe, Threema does appear to be the one recreation on the town. By the way in which, Threema can be topic to jurisdiction in Switzerland, and in contrast to Sign, the Swiss additionally complies with the provisions of the European Basic Knowledge Safety Regulation (GDPR).

In order for you a ultimate phrase on safety and knowledge safety: Sign is a very safe instantaneous messenger however Threema is just a bit bit higher. Are you looking out for probably the most safe messenger? Then you definitely would undoubtedly need Threema!

Threema vs Sign: Worth

Earlier than we arrive on the conclusion, let’s discuss very, very briefly in regards to the worth. Ought to we’ve carried out that initially of the comparability? Sure, maybe! However I believe this level should not be that vital, particularly in terms of instantaneous messengers which can be primarily about safety. Sign is free, whereas Threema isn’t. The moment messenger from Switzerland presently expenses $2.99 a pop. 

Anybody who forgoes an instantaneous messenger like WhatsApp or Telegram, the place we presume most of their very own contacts are positioned, will need to have an excellent motive for his or her selection of another instantaneous messenger. The safety degree is one such motive and it will be ridiculous then to quote the $2.99 charge as a stumbling block. That is why I need to point out it right here earlier than the conclusion, however I undoubtedly will not take it as an argument in Sign’s favor.

Threema vs Sign: Conclusion

We do not even should have an extended dialogue right here: Sign is forward in lots of elements: It’s much more versatile in personalization, provides extra options, permits you to probably discover your personal contacts and above all, it is usually free! With Sign, teams could be simply as giant as the info that you simply ship. So if you wish to use the extra full instantaneous messenger between these two, the selection would definitely be Sign.

However do not forget that this can be a duel between safe instantaneous messengers and due to this fact we’ve to pander to the consumer who solely needs to make use of probably the most safe messenger. In order for you the most secure among the many lot, then no different instantaneous messenger other than Threema can lay declare to that crown – not even Sign.

Nevertheless, it will be improper to dismiss Threema as a easy instantaneous messenger with a deal with safety! A few of its options are actually nice and modern, and I even just like the dealing with of the voice messages higher than on another instantaneous messenger. So in your cash’s price, you get a extremely useful chat service that does not should cower among the many different market choices.

I am such an instantaneous messenger fan, and I not solely use WhatsApp and Telegram, but in addition Threema and Sign. From my viewpoint, I can inform you that in each instances, you get far safer alternate options than WhatsApp and Telegram. If you’re extra into fancy shade choices, GIFs and performance, your selection ought to be Sign. For many who need to play it protected, go for Threema!
