Communication Apps

Definition

The message that matters is the one that arrives when the other person is in a basement with one bar. Communication apps carry calls, texts, and files between people you already know — phone numbers, work handles, or a small group thread. They are not social networks: there is no public feed to perform for. End-to-end claims, SMS fallback, and whether a call works on data-only SIMs are the facts that decide the pick. A sticker pack is not a messenger. If the product needs a phone number you do not want to give, that is a constraint, not a footnote.
