Absolutely brilliant

Secure , well built UI, reliable

Wish Americans would WTFU!

3ma is great. Way better than either whatsapp or signal or telegram…. Eons better. But Americans would rather stake themselves as the internal colonially displaced subjects whose existence is permitted insofar as it relates to the economic system of capitalism alone.

The best

Muy fácil de usar

If I could give it 0 stars I would

The app constantly takes 30 minutes or more just to deliver a message, and many times just disconnects from the network for no reason.

Missing self-destructing messages like in Signal, WhatsApp, Telegram, Session, Wickr, SimpleX.

We’re living in 2025 and Threema still doesn’t have self-destructing messages.

Feature request: Add self-destructing messages.

Edit: Useless messenger with no self-destructing messages even in 2026

Response from developer

Thank you for taking the time to write down your suggestion. We’re happy to review it as part of our internal evaluation process. Although there are currently no disappearing messages, it is possible to edit and delete messages manually. You can find more information about that feature here: https://threema.com/faq/editdelete

Terrible and expensive

Can’t believe they charged me $7

Megge

Great app, no incredible!

Easily one of the worst paid app I ever used

I don’t know how an app can be so buggy and unpredictable in this age. And this is a paid app for God’s sake! It’s easily one of the worst paid apps I have ever used. Always something or the other.. it doesn’t connect.. those red and orange lines at the top. Have to restart so frequently. Honestly surprised how this is still on the AppStore. Very frustrating user experience.

Issues

So many issues for a paid app.

The best, the safest messenger you ever need

Compared to all the other main companies and their messengers , multimedia platforms.This one is the only one what really gives you privacy and peace of mind!

Amazing

Proper anonymity

It has always worked great for people who want a real anonymous messenger. Many options to set it up and your profile shows your user ID for if you need it. End to end encryption. Works as intended.

Pour une application payante, on s’attend à mieux!

Threema est un beau projet qui mise sur la sécurité avant tout ce qui est pour moi très important. Malheureusement, récemment, beaucoup de petits problèmes viennent régulièrement altérer l’expérience. On reçoit tout à coup certains messages avec quelques heures de décalage, les appels ne sont pas très stables ou ne connectent parfois simplement pas. La connexion aux serveurs est plutôt capricieuse et imprévisible. Parfois tout marche parfaitement, et d’autres fois rien ne va. Je voulais réellement pouvoir faire de Threema mon appli de communication par défaut, mais malheureusement le manque de stabilité fait que je continue à faire des aller-retour avec Signal et d’autres.

Messages not sending/going through

For several weeks now, when I send regular text message and then get out of the app. It will not go through to the person I sent it to unless I open the app back up and it reloads and then it will send the message and if I don’t do it right away the message will literally take hours to be sent if I don’t go back into the app. The last couple updates have been trash and I’ve been having all kinds of issues like this and the app not even opening when I receive a message.

Exceptional

Excelente way to keep it everything private

ずっとこれ一筋です。

広告なくて相手とストレスなく連絡が取れる。当たり前のことだけど最高です。10年近く使っていますが、バグ対応も早く、信頼できるアプリです。開発陣の皆様、いつも対応ありがとう!

Response from developer

Provided that a stable Internet connection is established, messages are typically delivered within a few seconds if the background permissions on the recipient’s phone are configured correctly. We are happy to help if you need assistance in configuring the settings correctly: help@threema.ch

Не регистрирует

Не регистрирует, не приходит ID код

Says initialise then nothing

UPDATE: WON’T CALL OR RECEIVE CALLS. 🤦‍♀️ Do not pay money for this absolute waste of space. Zero support too.
—-
Very often won’t call. Says it’s initialising but doesn’t. I like it other than this.

更新后老是黑屏呀

老是黑屏!老是黑屏!老是黑屏!
希望修复!!!!!
希望改善 另外希望兼容一下低版本的iOS

It’s great, not spammy or scammy like other apps

I refer this to people that are caring and protectors
