PRIVACY AND ANONYMITY
Threema is designed from the ground up to generate as little data on servers as possible. Group memberships and contact lists are managed on your device only and never stored on our servers. Messages are immediately deleted after they have been delivered. Local files are stored encrypted on your mobile phone or tablet. All this effectively prevents the collection and misuse of your personal information, including metadata. Threema is fully compliant with the European privacy legislation (GDPR).
HIGHEST ENCRYPTION STRENGTH
Threema end-to-end encrypts all your communication including messages, voice and video calls, group chats, files and even status messages. Only the intended recipient, and nobody else, can read your messages. Threema uses the trusted open source NaCl cryptography library for encryption. The encryption keys are generated and safely stored on users’ devices to prevent backdoor access or copies.

No one should intrude in your 2 AM romantic chat or important business correspondence. This app permanently deletes each message from its server the second it gets delivered. No email address no phone number are needed to sign up. It's about as safe as it gets. more1 year ago

Needs delete for everyone option & viewed option for received messages
Jul 15, 2020 By Jale71I 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. more -
Best messaging app for security
Jul 9, 2018 By G-MoIf 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. more -
Sep 24, 2021 By A Google userit is very uncomfortable when I reply to message by swiping the message to the right, I cannot send a voice message. make this feature pls) there is a strong lack of highlighting messages for saving to favorites (undeletable), as in whatsapp. more -
Great at security, mostly great at the rest
Feb 22, 2019 By KokubuThis 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. more -
Sep 24, 2021 By Ismail MallemReally good only if there is possibility of disappeared messages, my argument for it is i use it a lot with my friends when speaking in very sensitive subjects instead of deleting messages manually you just make sure that messages will not be available after a specific time so you are safe if someone hacked your phone. and yes it's very useful if both parties agreed to it. is not security against the one who are chatting with but the one who might access your data one day. more -
Good but no “edit message” function
Mar 29, 2020 By satchnutThis 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. more -
Sep 6, 2021 By Andrew HancockVideo calls are better quality than telegram, duo, Facebook messenger, texts send fast, love the platform. What I don't like as much are the bugs. The videocalls, while fantastic quality video, are very buggy. The app does weird things sometimes, weird things freeze. Its still my daily go-to messenger because what I love about it is worth the sometimes annoying bugs. If you want perfect reliability, telegram is your vest bet. more -
Get this app now
Oct 6, 2019 By Zombie slayersI’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!” more -
Best app in the entire App Store
Mar 13, 2019 By PurpleMesaNo 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. more

An inconvenient communication app
Jan 1, 2019 By 程序员之家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. more -
Sep 19, 2021 By Sam TeslaNotifications only work half of the time (battery saving deactivated, app permissions activated). "Threema Web" is also only working half of the time. Threema allows only one admin per group chat, which can be awefull, when people wait to be added to the group (or refuses to). Of course you can always clone the group chat, lose the complete chat history, and annoy everybody by creating a new group chat (plus added people), and then tell everybody to ignore the old group chat. Check FAQ. more -
Sep 12, 2021 By T AFSorry rating 1, so that someone responds. Facing problem in rejecting calls. No matter how many times you slide reject button, it doest work. Also, my phone can mute the ring tone immediately, if I touch the power button. But it doesn't work with Threema. Puts in awkard situation, if you are in a meeting and Thrma starts ringing. Neither reject works nor mute. Also, sometimes my contacts are unable to receive my call, they only get missed call notification. When they call back, call connects. more -
Not impressed
Jan 26, 2021 By KeahilanikuponoWhile 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. more -
Jul 10, 2021 By Eric VollenweiderThe app does not work. I bought it on Google play store, open it up and it only says Error 291 along with a solution to clear Google PlayStore Cache and Storage. Doing that helped nothing. Other solutions I found on Google (Stackoverflow etc.) suggested the same steps, but did not work with this app. I never had any issues with other paid and free als before. I'll try to refund. more -
Aug 8, 2021 By Vas PatibandlaI bought and installed Threema but haven't used it yet. I didn't feel at ease with the privacy policy. Threema really needs to be available as a 7 day trial or at least post the full privacy policy. Confusing what is stored (other than a lot) and what is actually deleted. Understandable to help crime fighters but too many agencies, legal entities, and hostile governments around the world abuse their power for information (spying with no probable cause). Did get a refund though. Thanks more -
Jul 30, 2021 By meilla104Efficient about crypted messages, but very unstable. Something messages need hours to be delivered and calls are a nightmare. Most of the calls don't find the connection. When the connection is established, it always cut. Besides that, no Threema web for Mac... more -
Aug 16, 2021 By Skeleton Dad Gamingmissing an important feature, self destructing messges, it's enough for me to uninstall and go back to telegram, waste of money really who wants to manually delete every message? privacy is key but not when you have to scroll thru and delete 100 messges, long more

Aug 19, 2021 By Nico FrickeWorks fine apart from not being able to disable vibration for new messages. I turned it off in the settings but it still vibrates. As I really hate it when my phone vibrates for new messages this is actually a deal breaker for using this messenger more often. Edit: Seems to be fixed now. Therefore we are at 5 stars now. more -
Love Threema but,
Jan 25, 2021 By OmarBayatyI’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. more -
Aug 2, 2021 By Himanshu MittalAmazing messeging application, security which you can't find anywhere, literally anywhere. Based on cryptography and secure end to end encryption with public and private keys, Threema experience is like nobody else. Except from stellar privacy and confidentiality using key pairs, the app is designed very well, offering encryption features even for locally stored data and UI pin protection. Full data exports, Threema Safe backup and ID exports are all fully encrypted. Keep it up Threema 👍🔥 more -
Thank you Threema - you saved Slovakia
Aug 16, 2019 By Budfit007Your 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) more -
Aug 4, 2021 By Saurabh SinhaVery good app with lots of features and excellent security options. Two factor authentication is missing. It would have been an added advantage. Delete for everyone option needed. Twenty four hour status is required. Starred messages is not available. more

Great but behind on features
Nov 16, 2017 By secured2kThis 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. more -
Sep 20, 2021 By Anke KellermannLooks good so far, but some features are missing, like switching to a chat during a call to send a picture for example. -
Great, but needs a disappearing msg feature
Apr 9, 2020 By flyingsnowballSignal and others allow one to have messages over a user-definable age automatically erase from the device. Please consider this feature request. It also allows for shrinking the amount of data backed up and helps keep conversations ephemeral. more -
Aug 3, 2021 By Ton MusarajLooks good at the begginin! But has a few thing to improve and im testing it! First try to add timer messages disappearing, Second try to add optional photo sendind only view time and and the receiver cant save it on gallery! Try to be the best than signal on cybersecurity and more anonymously! I dont want when i send my phone to some technical support they can read my messages with tools etc. Try to improve and be the best to win my trust! more -
Well executed but missing some features
Sep 22, 2019 By Jay Van QuickOn 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). more -
Aug 1, 2021 By Wayne EverettWorks fine. No issues and is as easy to use as any other messaging app. Probably 5 starts if it would run in landscape mode.

You really need to add sync between devices
Jan 19, 2021 By WaswhatwerThis is almost a deal breaker, and certainly keeps from being able to use it for anything but messages that need to be secure. It’s one thing to deal with it for just your account, but when you tell that to other contacts and family it becomes impossible as most people just expect sync no a day's on iOS. more

Jul 30, 2021 By meilla104Efficient about crypted messages, but very unstable. Something messages need hours to be delivered and calls are a nightmare. Most of the calls don't find the connection. When the connection is established, it always cut. Besides that, no Threema web for Mac... more

An inconvenient communication app
Jan 1, 2019 By 程序员之家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. more -
Sep 19, 2021 By Sam TeslaNotifications only work half of the time (battery saving deactivated, app permissions activated). "Threema Web" is also only working half of the time. Threema allows only one admin per group chat, which can be awefull, when people wait to be added to the group (or refuses to). Of course you can always clone the group chat, lose the complete chat history, and annoy everybody by creating a new group chat (plus added people), and then tell everybody to ignore the old group chat. Check FAQ. more -
Sep 12, 2021 By T AFSorry rating 1, so that someone responds. Facing problem in rejecting calls. No matter how many times you slide reject button, it doest work. Also, my phone can mute the ring tone immediately, if I touch the power button. But it doesn't work with Threema. Puts in awkard situation, if you are in a meeting and Thrma starts ringing. Neither reject works nor mute. Also, sometimes my contacts are unable to receive my call, they only get missed call notification. When they call back, call connects. more -
Jul 10, 2021 By Eric VollenweiderThe app does not work. I bought it on Google play store, open it up and it only says Error 291 along with a solution to clear Google PlayStore Cache and Storage. Doing that helped nothing. Other solutions I found on Google (Stackoverflow etc.) suggested the same steps, but did not work with this app. I never had any issues with other paid and free als before. I'll try to refund. more -
Aug 8, 2021 By Vas PatibandlaI bought and installed Threema but haven't used it yet. I didn't feel at ease with the privacy policy. Threema really needs to be available as a 7 day trial or at least post the full privacy policy. Confusing what is stored (other than a lot) and what is actually deleted. Understandable to help crime fighters but too many agencies, legal entities, and hostile governments around the world abuse their power for information (spying with no probable cause). Did get a refund though. Thanks more -
Aug 16, 2021 By Skeleton Dad Gamingmissing an important feature, self destructing messges, it's enough for me to uninstall and go back to telegram, waste of money really who wants to manually delete every message? privacy is key but not when you have to scroll thru and delete 100 messges, long more
