Threema. The Secure Messenger App Comments & Reviews

Threema. The Secure Messenger Positive Reviews

Good, but buggyHas a lot of good features, and works a majority of the time, but has quite a bit of bugs. One of the bugs it has is that sometimes, during a video call, I begin to hear an echo of my voice. Once I end the call and reestablish a new connection, the echo goes away. Another issue just arose when I got 16.2, which is I won’t be able to hear the person I’m having a video chat with through speaker, but shutting the app down helps. Also has other bugs such as not given the option to use the camera unless I hold down on the users name from the contact list which will then give me the option to take a photo. There are a few more, but I could be here for a while. Just hoping some of these things can get resolved because they are quite annoying. That said, good app overall..Version: 4.8.5

Best messaging app for securityIf 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..Version: 3.0.9

Needs delete for everyone option & viewed option for received messagesI 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..Version: 4.5.4

Keeps freezingI use this app everyday and I like it, but it freezes alot. It’s been happening for months now on my IPhone. It used to freeze the moment I’d send a text or a picture through the app, but lately it even happens while I’m typing. It won’t look frozen; the text cursor will still be flashing like I’m able to type more but I can’t do anything. I have to swipe from the bottom and close out of the app, and then open it again. Happens about 5 times a day. This doesn’t happen to any other apps on my phone..Version: 5.5.2

Good but no “edit message” functionThis 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..Version: 4.5.3

Best app in the entire App StoreNo 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..Version: 4.1.3

Great at security, mostly great at the restThis 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..Version: 4.1.1

Easily doable features neededWe 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..Version: 4.8.4

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..Version: 4.6.4

Thank you Threema - you saved SlovakiaYour 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).Version: 4.3.2

Best app there isDon’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..Version: 4.3

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..Version: 4.3.2

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..Version: 4.6.12

Auto delete, c’mon fellasHere’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..Version: 4.6.18

Solid and safe, bud so buggy and subpar interfaceThis 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..Version: 4.6.13

Was Better before all the updatesRe review here… I understand you need to update apps to keep them relevant. I’ve had this app for years, but I will say all these new updates are making it far more complicated and far harder to navigate than it needs to be. It also is taking far more time to load with every new update. So, In my opinion, which means nothing, I think it was better before all these latest updates..Version: 5.5.1

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!.Version: 4.8.1

Would be of been greatThis app still need more option in their messaging system. Disappearing time need to be added in for safety reason. You don’t want someone phone to fall in someone else hands and have all old message read. Very scary situation for user. Also id need to be hidden better. Everyone shouldn’t be able to see your personal id in group. If they fix these problem this app would of been great.Version: 5.7.1

Absolutely great appThis 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..Version: 4.8.3

Great product but…Due to the nature of the beast there are sometimes delays in messages getting through. Again, goes with the territory of encryption and servers being used. Their customer service is wonderful and very prompt. Great product that, just like everything else, can use some tweaks here and there..Version: 5.6.2

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!.Version: 4.6.3

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!.Version: 4.6.17

Great but behind on featuresThis 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..Version: 3.0.2

Awesome messengerCouple 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..Version: 4.2.1

Well executed but missing some featuresOn 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)..Version: 4.3.2

Amazing app, lacks group permsFor just about anything I recommend this app to the fullest and was worth every penny. However I wish that when I made a group chat with friends I could choose who mod/admins the group-chat. Other than that perfect app.Version: 4.9.3

App keeps getting betterThe 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.Version: 4.6.17

Nice but could add a couple of privacy features.Message deletion for all parties as well as timed deletion options like signal. Also the desktop app is mostly useless because it requires your phone to be unlocked and the app open on the phone while using on your PC. Perhaps the devs can make some enhancements and make the app better..Version: 4.8.5

The best no question about that.First rule: you get what you pay..so 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..Version: 3.0.8

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..Version: 4.6.9

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..Version: 4.6.10

Not able to make calls after updateAfter updating, the app is no longer functioning for phone calls in China. I'm uncertain whether this is due to government restrictions or if the app has encountered bugs..Version: 5.6.1

Best Secure Messaging App!!I love great security! I love Threema’s commitment to a very secure experience! My only bummer is that here in the USA, I rarely run in to anyone that has heard of Threema and even fewer who use it. Most everyone I know of uses Apple Messages and are so committed to that service..Version: 5.4.1

New logoOnly 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..Version: 4.1

Almost perfect.The only thing missing is automated ephemeral messaging. I see the manual option, but would prefer to set a timer and have it done automatically as some other apps do. Any chance this is on the roadmap?.Version: 5.6.1

Happy userI'm very happy with the threema app which I use to keep up with family members. My only disappointment is that I cannot join in on the group chats using an iPhone. Is there a projected date for adding capability for group chat with iPhone?.Version: 4.9.2

Preferred secure messengerReally 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..Version: 4.6.18

Decent but still flawedIt serves it’s purpose, but is still flawed. Some messages do not go through timely (especially if media is involved). Calling rarely works. The few times that it does - reception is patchy at best. As a plain, secure messaging platform with no frills- it’s adequate..Version: 5.4.1

🤯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! 😇.Version: 3.0.3

It’s whatever.Found two typos when signing up… here is what I found… errors in quotations. Do you want to continue without enabling Threema Safe? When using Threema Safe “YOUR” can restore your Threema ID, contacts “,and” groups in case you “LOOSE” access to your device..Version: 5.0.1

Calling works off and onHaving 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..Version: 3.0.1

Missing messages with this versionMissing messages, the other person receive the notification but not the messages. happened couple times already. if is fixed l'll give 5 ⭐️.Version: 3.0

Not many people use thisSomeone add me or share their id.Version: 4.6.5

Great end-to-end encrypted chat appThis app has 1-1 chat, group chat, calls and video calls. Everything is end-to-end encrypted and app is from a Swiss company with servers in Switzerland. App is open source and audited to guarantee privacy is as advertised. Best thing is that the identifier is not your phone number or email address..Version: 4.9.1

Blocked in China.Blocked in China..Version: 3.0.9

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..Version: 4.6.17

Best messaging appWas 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!.Version: 4.6.13

Nobody I knowAdd me ID: TFXVHAVJ.Version: 5.7.1

The best chat appThis app is the best chat app for encryption & offers the same plus more options than any chat app it is beyond a 5 star rating in my opinion. It only has no option to hide or unhide active status which I feel for privacy reasons is good plus if trust 100 than I feel its a no need to know option. Wish I found this app long ago 👍👍👍.Version: 5.6.2

Need a thing to addPerfect app just need disapprearing message time option ..Version: 5.6.2

My go toFlawless privacy and go to app.Version: 5.5.4

The bestI like Threema their support is excellent most of all though l like their desire for privacy.I don’t understand why more people aren’t using it,maybe they need to advertise more and possibly have a phone book for those of us who are already on threema..Version: 5.4

AwesomeLove this app and customer support is excellent!.Version: 5.3.1

Perfection♥️♥️♥️.Version: 4.8

Not a wallpaper or background pattern fanLeast attractive update ever. Is there an option to cancel _all_ wallpapers as well, so I don‘t have to produce a plain white screenshot anymore to get rid of irritating patterns and other wallpapers?.Version: 5.2

Really well done!It’s private It works amazing No personal information Wow a company doing it right.Version: 4.6.18

La meilleure!Vraiment rien à dire de négatif ! Superbe application 👌.Version: 4.6.3

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..Version: 4.6.5

The best!La meilleur messagerie!.Version: 4.4.3

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..Version: 4.5

I love it but no notifications for messages after turning my phone back on everytime for 4.2.3The 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..Version: 4.3.2

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..Version: 4.3.2

4.2 Spanish Glitch50% 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..Version: 4.2.1

Love it ❤️This app is awesome it keeps me in touch with family overseas ...just love this app.Version: 3.0.1

Highly RecommendedAmazing chat app. Reliable and secure..Version: 3.0.1

Brilliant AppHands down best chat app, the fact that they are putting security first is commendable. Interface is smooth and easy on the eyes.
