Threema

I like the app basically. BUT on Windows Phone it is terribly buggy. Messages get constantly lost - even messages I sent myself. Notifications and Messages are often out of sync. Most messages containing photos can't be read. Last update has been rolled our months ago. I seems to me as if the Windows Phone port has been abandoned.

This is the ONLY privacy-focused encrypted communication app that I've found that DOESN'T require you to give up your phone number. It also lets you add PEOPLE IN PERSON manually WITHOUT NEEDING TO SCAN YOUR CONTACT LIST or leave any other unnecessary digital footprints. For that it gets 5 stars. Sure it might not look as good as some other apps out there, and the Windows Phone version is of course lagging behind the Android and iOS versions in the feature/customization department (like using your own photos for the chat background, or being able to nuke all data after a certain number of failed lock screen attempts), but it has it where it counts.

Thanks vor finally supporting Windows Phone! You guys are great! The App runs super smooth and has full fledged features just like WhatsApp but 100x more secure. and after its available for all major platforms it finally a true replacement. I'm currently converting all my friends to use Threema Keep up the good work!

Doesn't work any more

After the last update the app wont open chats. Reinstalled. Can't create new ID.

Doesn't work on Lumia 950 XL after update

Doesn't work on Lumia 950 XL after update. Please fix!

Kommt von der Performance immer noch nicht an WhatsApp

Mittlerweile etwas besser und stabiler. Viele Bugs wurden beseitigt. Die App ist aber immer noch langsam und braucht sehr guten Empfang damit Bilder raus gehen.

Full of bug.

Great application! Need to add more features and stability that are available in other platforms but so far I works great
