In their own words
Threema
Threema is a paid messaging service for private and business communication, supporting text and voice messages, voice and video calls, group calls, media sharing and file transfers. It can be used without a phone number or email address, and contact synchronization is optional. End-to-end encryption covers messages, media, calls, profile pictures, group names and group-member lists. The apps are open source, with repositories for Android, iOS, macOS, Windows, Linux and Threema Web. The regular desktop app and web client require a mobile device with Threema installed and activated. Threema operates its own servers in Zurich data centers of an ISO 27001-certified colocation partner. It says its apps receive regular audits by recognized security experts, including Cure53 audits in 2020 and 2024. Business tools include Gateway integrations, Work APIs and Broadcast features such as feeds, distribution lists, bots and managed group chats. Private use costs $6, paid once, with price varying by app store and country; Core starts at $3 a month billed annually. A 30-day trial is listed.
WhatsApp is a free messaging and calling app for Android, iOS, macOS, web, and Windows. Users can exchange text, photos, videos, documents, and location, and make voice calls. Voice and video calls are end-to-end encrypted, have no time limits, and work one-to-one or in groups across iOS, Android, and web; group calls support up to 32 people. Calls can also be made in a browser. WhatsApp says end-to-end encryption keeps personal messages and calls private from others, including WhatsApp. Privacy controls include locked chats, disappearing messages, encrypted backups, online-visibility settings, and blocking unknown callers. Users can report messages, people, or businesses, and block contacts. Up to four devices can be linked to a primary phone, which is required to register an account and link new devices. Minimum requirements listed include Android OS 6.0, iOS 15.1, macOS 12.1, and Windows 10 or newer; iPadOS 15.1 is also listed. Data charges may apply, and calls use an internet connection. WhatsApp Business helps businesses showcase products and services and build customer relationships.
