Threema. The Secure Messenger Comments & Reviews 2022

- Needs delete for everyone option & viewed option for received messages

I like Threema but was horrified to discover that one cannot delete messages for everyone. I did not realize that all messages would remain on the receiver’s phone. I get confused on Threema when I have listened to an audio message because there is no indication that I have already listened to it. A check or something would be nice. If there are many audio messages and one gets interrupted, then it is unclear where to start relistening again. I do not like the red while recording messages, it is very distracting to the eye. I would prefer a milder color. I also like that in WhatsApp I can type a reply in the reply box while listening to a message but that does not work in Threema. Otherwise, I like the clean design of Threema and the privacy.

- Best messaging app for security

If you want a pretty messenger, stick with the Messages app, Facebook, or maybe Signal - they’re all “secure”. If you want a secure messenger, get Threema. It sends messages securely from device to device, not user to user, so you need to think a bit differently about using it, but that difference in thinking is “this message is encrypted on my device and sent to that other device, which I’ve confirmed is the correct device by scanning its barcode”. This is handy (and one of my main uses) because you know that your snarky comment isn’t going to show up on your wife’s computer as she’s projecting her screen in the conference room at work. True device to device encryption, plus the company’s location in Switzerland with physical control over its servers, combines to make this a very secure messaging app. Even if you’re just using it to send snarky notes about employers, it’s worth the price.

- Great at security, mostly great at the rest

This looks like a messaging app written by people who take security seriously. Well done. I’m only taking off one star because the onboarding process was a mess. At one point, you’re asked to enter a password, and again to verify it. That’s all fine, but the password fields are so far down the page that the on-screen keyboard completely covers the second one — and the page doesn’t allow scrolling vertically! Eventually I discovered a workaround (tap Passwords, then Cancel, then tap the second password field, then blindly type your password on the keyboard that appears). But this is really something that should have been caught in testing. This makes it impossible (AFAICT) to paste a password from the clipboard, which discourages the use of strong passwords from a password manager. And that’s not good for security. Aside from that one major inconvenience, though, this looks like a great app.

- Not impressed

While threema works overall, I’m less than impressed with the audio overrides and the disconnects. If I’m on a call and play a video, the call will completely disconnect. If I’m playing music and merely open the app, it will kill my audio for about 5 seconds, and then artificially lower the volume. Drives me bonkers. I’m constantly having to go into my settings and revoke (or grant) permission to the microphone depending on what-else I’m doing. Very annoying and detracts from the usefulness of the app itself. I’ve contacted support and the only thing they could tell me was to upgrade to the newest version of it. I’m already running the newest version. It’s the only message app that has been incapable of handling audio in a competent way. Very disappointing to say the least.

- An inconvenient communication app

Such an inconvenient communication app for voice-messages. It doesn’t support running in iOS-background, which means it can’t automatically download voice-messages or images you received. Every time you get a incoming-voice notification, you have to open this app and tap the voice-message you received and wait for a long while to download it. If you don’t live in Europe, I strongly suggest you not to using it, because downloading voices-messages from Threema’s sever takes really long time. Not even to mention that if you receive more than one voice-messages, you have to tap them each one by one to download, waiting and waiting for these downloading processes. Too annoying!! What an era do we live in? Almost every communication app is now having this feature downloading media automatically.

- Good but no “edit message” function

This could be the perfect secure messaging app if it were “fat-fingered perfectionist”-proof :D, as having to copy, delete, paste, edit, then resend just to “edit” a single sent message is so much hassle compared to just hitting an edit-button. For now I and my similarly fat-fingered perfectionist friends will be begrudgingly sticking with the less secure alternatives for now. If this is ever implemented, I will start recommending Threema, as otherwise the UX feels solid, better than Wire’s and even Signal’s. By the way, if the concern is with potentially allowing people to edit maliciously, maybe a mutual-consent-based “Allow editing of sent messages in chats” switch is an appropriate solution. Or perhaps just an “Edit history” list.

- Get this app now

I’ve been using Threema for years It is by far the most safe and secure messaging app out there Once you pay for the original app, there are never any additional charges for any messages, pictures, videos, or texts sent... ever!! I used to pay a lot of money to send even just one text message to family members in Europe. Not anymore.. I hear this app is very popular in Europe, but somehow I don’t think it will ever catch on in the United States. But if you do purchase it, it is definitely worth it. You will need to tell your friends and your family members about the app because they need to have the app as well in order to communicate with you. Once anyone else has this app it’s the only way I communicate with them. They begin to use it too and it becomes your normal way of sending messages back and forth. Almost all of my text messages to people I know, go through Threema. Get this app and spread the word. Remember freedom means “No Big Brother!”

- Best app in the entire App Store

No need to give your phone number out to anyone. THREEMA gives you an ID which you use instead of your phone number. No other secure messaging application allows you to protect your phone number in this way. Also, because you pay for THREEMA you know exactly why they’re doing what they’re doing. For money from you. You’re paying and this your data isn’t the price. I’ve been with THREEMA since the start and their developers come with constant improvements and updates. I love this app because it means freedom.

- Love Threema but,

I’m giving Threema 5 STARS after it becomes open source but, what’s the point of all these features that added recently and Threema still blocked in many countries, what’s the point if I can’t call, text or send photos to anyone in my list. they can’t use Threema without a VPN 90% of my friends switched to another IM app because it’s available in their country’s that’s why Threema is not popular so until you find a way to use it without a VPN then we can enjoy all features otherwise it’s useless.

- easily doable features needed

We need to be able to delete messages from all devices similar to the app session. I’ve been sending all my friends $5 to convince them to join this app, I know it’s not much but I’ve bought about 8 accounts for people and that’s my only major complaint and why I still prefer session. If you can fix this I will be using this exclusively as will many people following me to the app.

- Thank you Threema - you saved Slovakia

Your app revelaed the biggest political scandal in the Slovak Republic history. All you need is to break inside (it took police some months to do it - you might work on more secure standards) of one of the biggest influential oligarchs who used it for long time. Now all Slovakia could read the messages and reveal the biggest political and economical thefts made by politicians, oligarchs, mobs. So big thank you for liberating our country. (all in the news last two weeks)

- Good privacy but quite some deficiencies

In general, it is a good app with high privacy standards. But the web version is highly complicated. Every time I have to try several times to make it work. It is very annoying. I don’t know if that has to do with privacy but there should be a way that I can just login with my password and it works. Also, I had friends that changed their phones and had lots of trouble getting the messages. I think they even had to, make a new account. I don’t know if it was really necessary, but they couldn’t figure out any other way to make it work.

- Best app there is

Don’t have to use a phone number to setup an account. That’s so massively important. They actually charge for the app which is a major positive if you care about what their motivations should be. Privacy first and then they basically try to copy WhatsApp on features. Always a little behind on the feature list but you’re choosing privacy over minor functionality bonuses. My favorite app and I couldn’t support this company or their vision more.

- The Best Secure Messenger!

Threema offers the best security of any encrypted messaging app available! Not only is it based in the pro-privacy country of Switzerland, but it has also been comprehensively audited by a reputable Swiss security firm and found to have no vulnerabilities. The other great thing that makes it unique is that only you have access to your private key and you can exchange public keys directly with friends and family, which proves the identity of your contacts. This robust authentication protects your communications to a greater degree than similar apps. For more confirmation, check out past Security Now podcasts for why Threema is the best and most secure messenger you can use. If you are looking for a messaging app that gets security right, look no further than Threema.

- Great app, but some slight issues.

Is it normal on iOS when recording a voice message, for voiceover iOS is built-in screen reader, to switch to the earpiece? I ask, because it makes it almost impossible to here, and determine where they stop/send button is, also the problem there, if you put the phone too close to your ear, the screenshots off. I'm running iOS 15.0.1.

- Auto delete, c’mon fellas

Here’s the thing: Auto delete might not be a 100% reliable (/ safe) feature, but not being able to delete messages is certainly 100% unsafe. Inform your users by a disclaimer and go on with it, not hide behind this silly pretense and cause negative reviews by people that either think they know better or are frustrated about messages that are forever saved on someone else’s phone. Just saw your app featured on The Terminal List, so much potential stopped short.

- Solid and safe, bud so buggy and subpar interface

This app overall isn’t terrible, but it is so buggy whenever I’m messaging anyone. Also the interface is weird and not placed weird. For example I’m constantly hitting the record button on keyboard while typing, but I have small fingers and it doesn’t happen texting on any other app or messaging. Anyway, it’s secure and it does what it has to do, that’s the only reason I’m not upset I spent money on this app.

- Excellent call quality and stability. Highly recommended!!!

We are calling half away around the world with very limited internet connection speeds, I mean very limited. We are amazed each time how clear and immediate the conversation can be. The stability is outstanding as well, calls are only dropped if I accidentally touch the wrong button!

- Lack of Phone Support & No Detailed Instructions re Use

The Threema App maybe superior and it may offer unique features that other Apps don’t offer. Yet, as a non-IT person, the ability to get the appropriate functions working without more comprehensive support or written instructions is a significant short coming. Chats are available but to get the benefits up and working appear to be a major effort. Inquiries were made to Threema regarding the availability of written instructional materials; it appears they are not available.

- Stellar Messaging App!

App has been great for my family and I. We’ve all switched over to messaging, video calls etc, via Threema. However, like with any app, some shortcomings. For example, on iPhone 14 Pro Max the text input bar is pretty narrow. Makes it difficult to tap on it to begin messaging. Another issue is when accidentally recording a voice message there isn’t an actual cancel button, so you will record until you click stop then you have to click off that main window in order to get a notification box requesting deletion. Some minor nuisances however this review is constructive criticism I guess. Keep up the great work!

- Absolutely great app

This app is great. It really proved itself to me when I stayed at a rental with restricted internet that disallowed photos from being sent over messenger. Their nosy internet settings couldn’t detect that I was sending photos with Threema. If you could add cropping to the in app camera (and other editing tools) that would be really useful.

- 1 thing missing…..

SELF DESTRUCTIVE MESSAGES IS A MUST. Other than that the app still deserves five stars because it is by in large the most trustworthy secure messaging app. Signal makes you linke phone number, Not Threema! You can use it totally anonymously. Clear pay for play profit motive. Still deserves 5 stars but please integrate Self destructive messages!

- Great but behind on features

This app is great for secure messaging and anonymity. I wish this app used a in-app purchase model so it could be downloaded for free to increase the user base. They could then charge an in-app purchase for features like voice calling, group chat, or other features that could be limited but allow for basic secure messaging for new users. However, for being a paid app, it seems to lag in features compared to competing products. I hope they add or fix some of these items: - Perfect Forward Secrecy on the end to end layer - self destructing and deleting messages - video calling - allow the user to do other messaging while a call is in progress.

- Awesome messenger

Couple of touches are missing, such as video call support and if developer can enable sent message edit function for short period of time i.e you can edit your sent message within first 20 seconds, then would be awesome. Another thing, instead of tap and select, slide right/left would be much easier.

- Well executed but missing some features

On the security side the application is very well executed. On the messaging side there are a few features that would be desirable to have; The ability to quote a picture. Read receipts on messages in group chats (who in the group has seen your message).

- App keeps getting better

The last few updates have made it even better. Please add stickers though. It’s the only feature I and my family still want from WhatsApp. Thank you

- Now has private investors. Can be compromised.

It's getting worse at sending messages in a timely manner. I hate WhatsApp, and I mean hate it. But it works consistently. NEVER an issue with WhatsApp. Threema, every freaking day. I'm starting to take it personally. We pay for this, and it holds up my messages, delivers them out of sequence or doesn't deliver them at all.

- the best no question about that.

first rule: you get what you if its free its crap or screwed you by the T&C. i like to see more support for the apple watch so that u can actually write a new message without the use of an notification of an unreaded message by the phone from the watch.

- Great app but it needs improvements.

I love the app and the idea of the ID and no contact & email sync but it needs a few features. 1. Expiring photo option (view once or forever). 2. Messages time duration (1hr, 1 day, 1 week etc). Other than those, it’s all good.

- This App is Great but...

I am experiencing a bad experience when trying to send some pictures in this app. It get to long to sending, and mostly it failed, because i can not wait the pictures loading before close this app and move to another things i need to do on my phone. Please do something. I never tried video, but if pictures get that long, wondering how long the video will take

- New logo

Only thing I’d change is the icon. If your using this app and don’t want people to realize it’s a messaging app it’s kind of hard. The picture logo is literally a message bubble with a lock in it, which is pretty suspicious. Other than that I think it’s great.

- Preferred secure messenger

Really needs more reactions options. The ability to “like” or HEART a message would be greatly appreciated. This feature is used by empaths on other platforms extensively. A thumbs up doesn’t cut it.

- 🤯No disappearing messages?!?🤯

I love this app and all the privacy features it has to offer but I am blown away that it doesn’t have the option to users to choose or burn their messages (or conversations?!?) I’ll definitely give this app ⭐️⭐️⭐️⭐️⭐️ if (once) it’s added! 😇

- Missing messages with this version

missing messages, the other person receive the notification but not the messages. happened couple times already. if is fixed l'll give 5 ⭐️

- way bettet then zoom 😆🇺🇸🇺🇸🇺🇸

you should incorporate AI generated qr codes to every call and message for full anonimity👌✌️ i would pay 5 to 10 dollars if that was incorporated you could dominate britan,germany and china. maybe AI random generated IP address as well?

- Needs to be fixed since last update

Ever since the last update the voice message recording has a bug. It records super silently and you have to pretty much hold the speaker right to your ear to be able to understand. Even if the volume is all the way up. Please fix that issue! It's very annoying!

- Calling works off and on

Having some issues with calling to another threema user it will ring sit on connecting and then disconnect. Work fine a couple times and had just stopped.

- Needs option for disappearing messages

Nearly perfect, but I hope they can include an option for disappearing messages in the near future, like signal does.

- Alright app

Cool interface, and solid security protection from remote devices accessing information. I would recommend that they create a burn on read feature similar to wickr that deletes messages as they are read. Good protection unless someone has access to your physical device.

- Reset

I like this app but I just reset my phone and lost the app now I’m trying to open it again I’m not able please someone help me thanks. If I forgot my password any option to change it?

- Want a refund- not transparent

I want a refund, they are not a transparent company. They are suppose to be a opened source company but now have private investors. Do they let their customers know, no. You could just a app such as signal for free and have the option to have the messages auto delete and delete messages for everyone.

- Message Retract

You should be able to retract your messages and it doesn’t have this feature. Or Message expiration where messages get completely dusted after certain amount of time

- Screenshots

For added security I would recommend being unable to screenshot messages like Confide. I love Threema. Keep up the great work.

- Nice App, but need emoticon support to text messages

The app is nice and secure but I find it difficult to react to people’s messages. I do not like to use the quote because it takes up to much space. Use something similar to Apple when reacting to a message. If everybody reacts to a message it takes up too much space on your display!

- Customize icon

Can you please give us the option to change the apps icon?

- Password

I don’t understand why in an upgrade some time ago they took away the letters under the numbers (as on a telephone) and never put them back. For me this makes it harder to use because I remember letters more easily than numbers, hence I have to look up my password, hence I use less.

- down for the whole day

been using this app almost 6 months now. A good and bad experience. Threema is down today can’t make a call the whole day or accepting calls either. I needed to make calls every hour to out of country relying this app and totally useless.? hope they fix it now

- I love this Messenger

For several years I use this tremendous messenger. My family and I are very satisfied with the service which Threema provides. For several years I use this tremendous messenger. The performance & privacy is excellent, fast, calls are excellent (clear) and the videos called . Threema for its price offers excellent product and service. Thank You ! Threema .

- Web Client

Threema says that due to Ios/Macos limits Web client can only be used with iOS app running on background. I wonder how Whatsapp can overcome this but Threema can’t.

- I love it but there is no Mac version

It’s a great secure messaging app with huge potential but still needs some improvement. Hope it can support Mac OS soon!

TransferWise 💸

Enjoy high maximum transfers into more than 20 currencies while saving up to 90% over local banks! The cheap, fast way to send money abroad. Free transfer up to 500 USD!

- Good app, but hide stale contacts is the dumbest feature I have seen in a while

This is a very nice messaging app with excellent privacy features, but the feature to „inactivate“ and hide contacts that have not been on there is really the dumbest thing I’ve seen in a while, and I doubt it’s tested with users. From my perspective: 1) It will certainly hurt uptake of the app: Most people who decide on whether or not to use the app will check how many people are on there. Seeing only a few contacts will discourage them. See network effect. 2) Having „(inactive)“ display next to your name for 24 hours after you started using the app again just feels plain weird in an app that is boasting it’s privacy features. Who says I‘m inactive? And why doesn’t the very action of sending a message determine activity? Also, having to chat with „inactive“ contacts with the constant reminder that they are deemed inactive (it shows in the chat and in notifications) is an unpleasant experience.

- Anonymous

Now if only there’s disappearing messages and Threema would be perfect

- Well maintained and secure

I’ve been using Threema for over five years. It’s constantly improved, secure and has a great feature set. I’ve never had it crash. Paying for it is a great, sustainable idea. I recommend anyone serious about privacy consider using Threema.

- Not bad but no Burn on Read timer!

It’s not a bad app but in the scheme of things is really no better than any other encryption messaging app. The biggest downfall of Threema is the lack of ability to have messages deleted on both ends either upon reading or after a set time eg; 5mins, 30mins etc. it lacks the privacy users are wanting in an encryption messaging app.

- Can’t edit or delete for all

Great principles this app but very inflexible - can’t edit messages or delete for all. Also no Mac desktop version. Will keep using unencrypted alternative for now and watch to see if this app improves.

- Highly Recommended

This is without a doubt best in class for security and data encryption. Highly endorsed. Great job

- Everyone should be using this

East to use, perfect UI and totally secure

- Fantastic

A really great messaging app!!! It pains me to use other messaging apps now that I use Threema. Threema is definitely in a league of its own.

- Auto Delete

The app needs auto delete, it does not have this function this its downfall.

- Push notification

No notifications even on Lock Screen. FIX ASAP!


This was meant to be the BEST from the REST.. every time you make phone calls it breaks up and I believe it’s not 100% encrypted and insecure.... IF I COULD RATE YOU IT WOULD BE ZERO!!! Who ever is running it should be sacked ASAP.👎🏽

- Solid effort at encrypted communication

Excellent app so far with a little room for improvement.

- Auper

Worthy alternative to others. Safe an easy to use

- Good app

Nice easy to use interface. I wish it used the Axolotl 2 protocol like TextSecure.

- Usabilty average

There is still no high-res support for the latest ipad even after the most recent update. Disappointing. Until this is fixed it's unusable for me. Two stars.

- Awesome secure messaging

Secure messaging done properly. Exactly how I envisioned it working. Love the 3 star system and the QR codes.

- Perfect

End to end encryption. Clean. Fast. Dark theme was the cherry on top. Keep it up.

- Best messenger ever!

So much better than WhatsApp! Very neat app, secure and super reliable! Perfect messenger!

- iPad support!

Needs to support iPad.

- Perfection


- blocked in China.

blocked in China.

- Really well done!

It’s private It works amazing No personal information Wow a company doing it right

- Love it 👍

The app takes privacy to the next level and then some. Unlike Telegram and Signal you don’t have to provide a phone number (or even an email address) although you could for convenience. Call quality is great and texting works flawlessly. Well worth the small one-time investment.

- Call Quality is great, video crystal clear

I am looking for best call quality, I can say the audio quality is way better than most apps, but group audio / video call feature is missing. Slightly buggy at times, but overall great.

- Best messaging app

Was initially apprehensive, but really glad we chose Threema! This is the best messaging app I have used and on top of it has real security features. Well worth the one time cost. That small payment got rid of all kinds of spam, noise and unwanted connections on Telegram/Whatsapp. Very nice feature that it is not necessary to use your phone number or even an email in order to sign up. Very very happy with this app!

- Meh

Mediocre messaging app. It crashes quite a bit then when the prompt to send report pops up it disappears before I can hit submit. Sometimes messages get stuck as undelivered for some time. Cannot receive phone call while on a call in this app or the app call drops. On occasion when answering a call one or the other persons can hear but can’t be heard. Have to hang up and call back. When on a video call one or the other person can’t hear or be heard by the other person. Have to hang up and call back. When an alarm goes off while In a call the call drops. Keyboard disappears randomly. Have to close app and open again to get it to reappear. Options at the top to open media, contact picture and call button disappear randomly. Have to close app and open again. I don’t think a day has gone by without some kind of bug but it’s better than WhatsApp and all those other privacy compromising messaging apps

- La meilleure!

Vraiment rien à dire de négatif ! Superbe application 👌

- Can we get GIFs please?

Threema is a great very reliable messenger that finally respects the privatsphere of Personal messaging. However, even after years into the business, and especially not at the current run for WhatsApp alternatives, people are missing some toys. Since I also on signal, I fell that chats there are much more fun just because of the use of GIFs. It would be great to see a GIF library integrate to Threema, too.

- The best!

La meilleur messagerie!

- Dark mode.

Please bring back the possibility to select dark mode (or other king of appearance change) inside the app (user can override the systemwide settings) to have the possibility to distinguish threema from other texting app.

- I love it but no notifications for messages after turning my phone back on everytime for 4.2.3

The older version would notify you of messages as soon as you turn on your phone. On the latest version of Threema (which I got this year), if my phone is turned off and someone sends me a message, I don’t get any notifications at all even when my phone is turned back on already. I flew to Europe so I turned my phone off during the flight. My friend sent me a message while my phone was turned off. After landing in the airport, I turned my phone on. I got notifications for my emails and texts, etc right away with no issues. But Threema never gave me a notification for the messages that I received during the roughly 10 hours that my phone was turned off. Also, my friend said that she only saw the envelope picture next to the message that she sent me which meant that it was only sent to the server so she thought I blocked her too LOL The same thing happens everytime my phone has no battery and loses power. As soon as I turn my phone back on, no notification for messages. I love Threema but how do I fix this issue? I would like to be notified for messages sent to me while my phone is turned off, even without opening the app, as soon as I turn my phone back on again. The older version used to do this. Thank you.

- Enjoying the app so far!

The only thing I’d like to see is more sound choices for messages; I think a greater selection would be nice or maybe even the possibility to choose a tone that you have on your phone. I like the sound selection for calls though, they all sound pretty neat — maybe some similar tones in a shorter sequence could be made for messages? Overall though, it’s been a pleasant app to use thus far.

- 4.2 Spanish Glitch

50% of the app text is now in Spanish, yet I am French and my device is set to French! Had to downgrade to 4.1.3 for a bug-free experience. AVOID 4.2 Edit : 4.2.1 working fantastically well. I recommend updating to this version. 5 Stars.

- Love it ❤️

This app is awesome it keeps me in touch with family overseas ...just love this app

Amazing chat app. Reliable and secure.

- Works really smoothly

Spread the word, invite others and get your privacy back!

- Good app

So far so good keep it up so fast and smooth

- Great App

Simply the best secure iOS messaging app out there.

- Can't use on extra device

Great chat functionality throughout, with end to end encryption as a bonus.

- Brilliant App

Hands down best chat app, the fact that they are putting security first is commendable. Interface is smooth and easy on the eyes. The icon has even grown on me, although I'd be interested in seeing it's appearance change. Thank you for putting your time and efforts into such a great app.

- Love it! But…….

Needs iPad version……Also needs to be able to reverse the camera in iPad.

- Greatest app!

So far so good! Will love to have yahoo! Emoticons instead on worthless emoji... Hope the app will stay stable ! Very nice so far! Plz increase video length (1minutes is nothing!)
