Morse Messenger vs Session
No phone number, and nothing left out
Session leaves the phone number out and routes messages through a decentralized network. Morse leaves the phone number out too, and adds what everyday conversations need: voice and video calls that are simply on, forward secrecy, and post-quantum key exchange.

Getting started
How conversations start
Both start without a phone number. What you share to connect looks different.
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.
Session
Session creates an Account ID for you when you sign up, with no phone number or email. You start a conversation by sharing that ID with the other person.
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.
Session
A Session account is identified by its Account ID. No phone number, email address or other personal detail is needed to create one.
Security
Encryption and network
Strong encryption is shared, the protection around the keys is not.
Both Morse and Session encrypt messages end to end. They differ in how the keys are protected over time, and in the network the messages pass through.

Features
Features and scope
Both cover private messaging. Morse is the more complete everyday messenger.
Morse
Share end-to-end encrypted messages, photos, videos, voice notes, stickers, locations, polls, quizzes, checklists, and more, without adding a public social layer.
Session
Session offers messages, attachments up to 10 MB, groups of up to 100 people and disappearing messages. Voice and video calls are an opt-in beta, and during a call your IP address is shared with the person you are calling.
