  • Needs delete for everyone option & viewed option for received messages Jul 15, 2020

    By Jale71
    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.

    Looks promising indeed. Does not need linking to email or phone number.( you can link but that kills the idea). It's the Holy grail of privacy for all who are searching here & there after WhatsApp fiasco. Signal is good for common users, Telegram might be good for the undecided souls trapped between more privacy and ease of use. Whatsapp is suitable for those who ONLY want free lunch & don't care being a product or a corporate slave for data mining rather than being a user with peace of mind.

    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.

    This is a good app with some nice features, particularly uncompressed image sharing. A couple of things I'd suggest. Why can't you thumb up posts in group chats? This is an essential feature for me. A quick response option, the perfect lazy solution. The other thing is the chat bubbles. Grey, grey, grey everywhere. It's a bit bland. I prefer blue, like Signal and iMessage. Some colour options would be nice. Other than that, a decent effort indeed. Keep up the good work!

  • Great...needs a few changes Jan 8, 2020

    By Charlie Full
    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.

Please do something. I never tried video, but if pictures get that long, wondering how long the video will take

  • Get this app now Oct 6, 2019

    By Zombie slayers
    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!”

    Awesome application! It's a little bit hungry for battery, especially when you're using the web access in your browser. That'd be something to improve :)
  • 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.

    I DO NOT LIKE the storage setting. This is one of a few apps i highly recommend for people interested in taking back their privacy. However there is a setting that deletes anything over 1 year. Why do i need to have this as an automatic feature? Why cant the time be customizable up to indefinate? Is not the media stored on the users device? Is.this app transitioning into a dictative place on user's devices? This app was paid for. It was not free! Atleast it was not for me! Caution!!!!

    Now. it would be a very good idea for Threema to provide this app for free for a short period... You would prove a big flexibiliy and enforce the much better alternative to WhasApp, in a time where people are looking for alternatives. This would make it easy for all those who already bought the app as well...

    I like everything about Threema: The approach towards data security and the official stance on privacy. The decision to go open source. The user interface is clean and simple. It's all good. Unfortunately, there is one deal-breaker: Calls between Europe and South-East Asia frequently drop. Regardless of the Internet connection, almost every single call sooner or later drops and is difficult to reestablish. As if the data connection had gone dead. Without this deal-breaker, Threema would be five stars.

  • Good but no “edit message” function Mar 29, 2020

    By satchnut
    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.
