# Compound

> Compound is a zero-based envelope budgeting app for iPhone, iPad, and Mac. Give every dollar a job, then spend normally — Apple Pay, voice, or type — while live envelopes show what’s left.

Compound helps people budget without end-of-day receipt catch-up. It is built for the Apple ecosystem and focused on calm, accurate envelope balances.
