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. more9 months ago

Needs delete for everyone option & viewed option for received messages
Jul 15, 2020 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. more -
May 9, 2021 Review #: 1 There are commendable features wherein one can set the app to automatically reject an incoming mobile call while a Threema call is active and enable or disable Threema video and voice calls (makes sense if one wants to use Threema only for messaging). Above features are non existent in WhatsApp. more -
Best messaging app for security
Jul 9, 2018 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. more -
May 5, 2021 Great app! So far, it seems Threema is doing a great job filling the niche of a private chat app that isn't harvesting your data. Worth the price and then some. -
Great...needs a few changes
Jan 8, 2020 I love Threema and the spirit of the developers' vision. I really trust this company. They just need a few additions. Needs a delete for everyone feature. This is very necessary for a number of reasons: error in typing, privacy, etc. Needs to make indicating bubbles of phone calls less intrusive, as they take up the same or more space as actual messages. Need conference calling. Near perfect app. Thank you. The ability to quote a picture...any message to or from. Also read receipts in group chats. Actually, this might catch on in the USA. I've got people looking at it. But still need to differentiate calls from actual messages in appearance. more -
May 9, 2021 I started to trust this app and hope you keep up with the promises made and keep privacy top priority all the time ! -
Apr 14, 2021 They made a change which forces all text messages to be condensed. You have to tap a button that says "read on" which will allow you to read that one message in full. You must then condense that message again to see any other message. Would be great if this feature was made optional so we could disable and just see the full text of every message. more -
Great at security, mostly great at the rest
Feb 22, 2019 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. more -
Get this app now
Oct 6, 2019 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!” more

Apr 19, 2021 Strangely not working? The app is amazing and well worth the money... But for some strange reason it's just completely stopped working. It can not establish a connection anymore. Sad if I had to find a new app because I really love using this one 😔 more -
Not impressed
Jan 26, 2021 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. more -
Mar 26, 2021 The setting for "original" photo size and no compression for video DO NOT WORK! I sent a 5.5MB photo, ir was received as a 500KB photo. When I sent a 250MB video, it was received as a 20MB video and the quality of BOTH are noticeably worse. Those settings do NOTHING. I am sick and tired of saying this. You also cannot send files larger than 50MB which is tiny. Telegram allows 2GB files. Finally, there are no read receipts on voice messages. Why not? I can't find a reason to use this over Telgrm more -
Apr 6, 2021 No automated backup method to off-device locations. Phones get lost, stolen, and break- and I don't want to suffer the loss of all of my messages. Otherwise a seemingly good and safe messenger. EDIT: Reduced to one star, as the dev who responded to this rating clearly did not read my concern. The article the dev comment points to explains how to do manual backups to internal storage. more

Mar 4, 2021 Great application in the functional simplicity. Gets 5 stars with hope that next update fixes the problem with push notifications not working in Android 9 and 8. [Update: Was fixed a while back - awesome dev team] Swiss perfection displayed in a great application. Let's see the updated fix soon dev team. I know it is cold there, but I'm sure you will come through. more -
Apr 19, 2021 Love this app and what it does, but it's so difficult to convince people to use APKs to install if you buy this for them. It sounds silly I know. But being able to gift on Android would solve so much in spreading this 🙁 5 stars - I can't fault Threema for Google Play not supporting gifting paid apps. more -
Best app in the entire App Store
Mar 13, 2019 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. more -
Apr 23, 2021 Great app!!! Does what it says, and does it reliably. No stupid ads. No nonsense. Simple, and Straight forward. Way better than other private messaging apps that i have tried in the past... Definitely worth the small fee... I am impressed... more -
Mar 24, 2021 the best messaging app hands down dont bother with others if you want security this is it.. only thing i would add would be auto delete messages after a certain time period.. also can we add auto destructive messages after set time period It's been almost 2 years now.. I still like it but it's feeling dated .. needs self destructing messages.. it's not bad just not great more

Great but behind on features
Nov 16, 2017 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. more -
Mar 2, 2021 The app is very good no complaints however I don't understand why Threema doesn't implement a auto delete or burn feature. It's almost like an archive of old messages at least implement the option to delete messages for both parties in the chat? Even what's app does this? What is the reason this has not been implemented? It seems like it's archiving the conversation and we have no other choice more -
Apr 25, 2021 I've got notification today on Samsung S20 that Threema is requiring access to Threema account. Combined with fact that I neither used nor launched Threema for weeks it seems suspicious. If this is change in architecture of the software users should be notified before such permission requests as your users may also be afraid of state actors which could be in position to substitute binary with other. more -
Great, but needs a disappearing msg feature
Apr 9, 2020 Signal 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 -
Well executed but missing some features
Sep 22, 2019 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). more -
New logo
Feb 10, 2019 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. more

Apr 14, 2021 They made a change which forces all text messages to be condensed. You have to tap a button that says "read on" which will allow you to read that one message in full.

Good but no “edit message” function
Mar 29, 2020 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. more -
You really need to add sync between devices
Jan 19, 2021 This 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

What’s Groovy
Have been using Threema for several years now; more or less. Well, rather less. The reason for this: relatively few people around me use it. Unfortunately! The concept is 💯 times better than Whatsapp and has some functions that Whatsapp & Co. don't have. AND, I never had any concerns about the use of my data. Does it cost any money? Yes! And I'm fine to pay for Threema, cause I don't pay for that by disclosing my privacy. Let me say: Guys, support your own privacy, support Threema using it!

What’s Subpar
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.
