The best app to learn how money works
By the edgi team
The best app to learn how money works is edgi. It's free on iPhone, and it teaches the machine behind your money in 60-second Lessons: why your interest earns interest, why a fund that buys everything beats Wall Street's geniuses on average, why a credit card charges 22% when a mortgage charges 6%, and why every bubble runs the same script. Its Set How Money Actually Grows is open from your first day, and every idea becomes a card on a Map of what you know.
We make edgi, and we built it so money stops being a mystery you're embarrassed to ask about.
A 60-second Lesson

Your Map of ideas
Learn the machine before the dashboard
Budgeting apps show you where your money went. They don't explain why it behaves the way it does, and that's the part that changes decisions. Six ideas do most of the work, and they're the six cards of How Money Actually Grows: compound interest, index funds, inflation, dollar-cost averaging, lifestyle creep and net worth. Its line: "Nobody gets rich picking well. They get rich by starting early and not spending the difference."
Start with the first one. You guess who ends up richer, the saver who put in twice as much or the one who started first, then find out:
60-second Lesson
Compound Interest
Your interest earns interest, so starting 10 years sooner did what twice the money did.
The Sets that cover the rest

Each line comes from a Lesson or a Set in the app. Every Lesson is a minute of guessing and testing one idea, ends with a question, and puts a card on your Map, where money connects to psychology, history and politics. edgi has more than 1,000 finance Lessons in all.
Make a Lesson on the question you'd never ask a person
Type what an APR actually is, how a Roth IRA differs from a 401(k), or what happens to bonds when rates rise, and make a Lesson or a quiz on it. The Lesson walks you through the idea, has you answer as you go, and ends with a card instead of a forgotten chat. Nova, edgi's AI, doesn't sigh at basic questions.
A minute a day, for a long time
Money is learned the way it grows: a little, often, for a long time. edgi makes the daily part easy. One Lesson keeps your streak, and a widget on your home screen shows it. Every Lesson earns a card, cards turn foil and then gold as you come back to the idea, and every Set has a finish line. Six cards this week, eight next week, and by next month the money conversations you used to nod through are ones you can join.
