Morse Messenger vs Threema
Same starting point, taken further
Threema showed years ago that a messenger does not need your phone number. Morse starts from the same idea and takes it further: there is no way to link a number or an address book at all, messages can disappear on a timer, and the encryption already includes post-quantum key exchange.

Getting started
How conversations start
Neither app requires your phone number. Morse never asks for one at all.
Morse
Morse does not use phone numbers or email addresses. You create an account with a PIN, without providing personal information. Conversations start by sharing a short Morse ID or scanning a QR code. There is no contact syncing and no upload of your address book. No SIM card is needed either: Morse works on Wi-Fi alone.
Threema
Threema gives every user a randomly generated Threema ID when the app is first opened. Linking a phone number or email address is optional, and so is synchronizing your address book to find contacts.
Identity
Identity and accounts
What an app requires to identify you shapes everything that follows.
Morse
Morse accounts do not require a phone number or email. A Morse ID is shared intentionally, and an optional encrypted profile can be shown to approved contacts without creating a public identity.
Threema
A Threema account is identified by its Threema ID. You can use it without adding personal details, or choose to link a phone number or email address so that people who already have them can find you.
Security
Encryption and design
Strong encryption is shared, post-quantum protection is not.
Both Morse and Threema encrypt messages and calls end to end, so the service cannot read them. The difference is in the protocol behind it.
Morse
End-to-end encryption based on the Signal Protocol
Post-quantum key exchange (ML-KEM)
No phone number or address-book upload
Threema
End-to-end encryption with its own protocol
Elliptic-curve key exchange, no post-quantum algorithm
Open-source apps
Business model
Sustainability
How a product sustains itself affects its long-term direction.
Morse
User-funded
Morse is funded directly by a user subscription, with no advertising or behavioral profiling.
Aligned with users
Threema
One-time purchase
Threema is sold as a one-time purchase and financed by app sales rather than advertising. The company has been owned by investment firms since 2020, and by Comitis Capital since the start of 2026.

Features
Features and scope
Both cover everyday messaging. Morse adds disappearing messages and post-quantum protection.
Morse
Share end-to-end encrypted messages, photos, videos, voice notes, stickers, locations, polls, quizzes, checklists, and more, without adding a public social layer.
Threema
Threema offers messages, media, polls, voice and video calls, group calls and a desktop app. It does not offer disappearing messages.

Who is it for
Which one is right for you?
Both keep your phone number out of it. Morse takes the idea further.
Choose Morse if:
You want an account that can never be tied to a phone number, email or address book
You want disappearing messages with a timer for your chats
You want encryption that already includes post-quantum key exchange
You want messages, calls, stickers, polls, quizzes and checklists in one private app
You think it makes sense to pay for a product that should stay private
Choose Threema if:
You prefer to pay once instead of subscribing
You need a desktop app or group calls today
You value open-source apps
Same starting point. Morse goes further.
Threema and Morse agree on the essential point: a private conversation should not need your phone number. Morse takes it further, with no way to link a number or an address book, messages that disappear on a timer, and post-quantum key exchange.
Start a conversation that stays between you and the people you trust.
Simple. Private. Independent.
