Threema. The Secure Messenger - Reviews, Revenue and Downloads - Apple App Store

Description

Threema is the world’s best-selling secure messenger and keeps your data out of the hands of hackers, corporations, and governments. The service can be used completely anonymously. Threema is open source and offers every feature one would expect from a state-of-the-art instant messenger. The app also allows to make end-to-end encrypted voice, video and group calls. Using the desktop app and the web client, you can also use Threema from your desktop.

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).

ROCK-SOLID ENCRYPTION
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 the users’ devices to prevent backdoor access or copies.

Threema is not only an encrypted and private messenger but also versatile and feature-rich.

Calls don’t work much

Messaging is OK, probably secure, but calls get stuck at initialisation 80-90% of the time.

Features

Not bad but still lacks what are these days basic functions. Please add the ability to make admins on groups, and timed messages on chats! Features which both Signal and WhatsApp have and make total sense. Also more reactions than thumbs up and down for individual messages would be a nice to have. Keep up the great work!

Freezes on private chat

I like threema a lot and would give probably 5 stars but can’t as on private chat freezes then need to be completely restarted app. PLEASE FIX IT

Was amazing now crashes almost ever other sentence.

Even on a new phone I find the app slow to open eg takes 8 to 13 seconds to pop up with Face ID check on iPhone 15 Pro. Find the app crashes almost ever other sentence. Never used to be this bad. Tried remove old history and tried fresh install but no difference

Excellent App

Threema is concerned with one thing, and one thing only - privacy. To this end, Threema is, imo, the most secure messenger app out there. Nothing in life is free which is why I like paying for my privacy and security. Great app, keep up the good work.

Hang issue

While during call many time app hanged and disconnected the call automatically and app went crash. Please fix this issue.

Nothing worth buying

Whilst this secure messenger does what it says to a degree there are other applications that do it for free. I’ve had most video connections not connecting and saying trying to connect when both phones have got full signal. This I know for a fact, as I have trialled them side-by-side and can see what is on the display in both instances. I certainly don’t think this company yet has the sufficient infrastructure for video calling compared to the likes of Facebook et cetera hence bad quality calls even when they are connected at best. The other slightly annoying thing is, you cannot customise one or two of the notification sounds you end up with the default one which is horrible and for a paid app this shouldn’t be the case.

Pretty good

Ive been using threema for years now. Security wise its good. But i still think it lacks features. 1- id like there to be sending/delivered/read notifications on group chat messages. 2- the same thing many people have requested for yeaaars! Is auto deleting messages. Always same answer: “its not as secure as u think, people can still take image with another device” yada yada Yes, but its still a good feature to have, and has been requested countless times. And its not just about security. It saves memory, time and hassle. Ive had chats that end up lagging a LOT and i have to empty the chat, but it can take a good 10-15 mins to empty and i cant do anything else until its done. Just add the auto deleting feature and add a disclaimer. I suspect theres another reason why they wont add it and wont say what it is.

Edit sent messages

I’ve been using Viber for a few years and wanted a change. This App is not free yet it has less features than Viber. Can we add a feature to edit sent messages?

Gol standard in encrypted communications

I have been using Threema for the last 7+ years, the bottom line very happy with the voice and video chat experience without exploiting its users. Keep up the great work Threema team!
