The best app for AP Macroeconomics
By the edgi team
The best app for AP Macroeconomics is edgi. It's free on iPhone, it covers all six units of AP Macro in 60-second Lessons, from opportunity cost to the Phillips curve to exchange rates, and it's strongest exactly where students struggle most: money, banks and the Fed. Each Lesson walks you through one idea and has you play with it: you predict what the Fed's move does to rates, tap to test it, and see the chain run. Make a Quiz on any unit or an Explainer on the graph you can't read yet, and you've built your own study guide. Every concept becomes a card on a Map of what you know.
We make edgi, and we built it so the economy stops being a diagram and starts being a story you can follow.

edgi has more than 2,700 economics Lessons and more than 1,000 in finance. For anything your teacher covers that isn't listed, make a Lesson on it.
Unit 4, made concrete
Unit 4 is where AP Macro gets abstract: money backed by nothing, banks that create money by lending, a Fed that moves interest rates by trading bonds. It's also where edgi is at its best, because two whole Sets live there.
Why Money Is Worth Anything is seven cards: barter, the gold standard, fiat currency, central banks, the US dollar, inflation and Bretton Woods. Its line: "Your money isn't backed by gold. It's backed by everyone agreeing not to ask what's underneath."
How America Rolls Over Its Debt is nine cards that carry you from Unit 5 into Unit 4: deficit spending, the national debt, Treasury securities, auctions, maturity, yield to maturity, the yield curve, market liquidity and open market operations. Here's the last one, including what changed in 2008:
60-second Lesson
Open market operation
The Fed buys and sells bonds to steer interest rates, not to pay the government's bills, and since 2008 it mostly steers by other means.
Build your own practice
Type what you need and edgi makes it. "Quiz me on Unit 3" gets you a 20-question quiz. "Quiz me on what happens when the Fed sells bonds" gets you one on the exact chain the free response asks about: money supply, interest rates, investment, real GDP. "Make me an explainer on the loanable funds market" gets you a few minutes of audio, screen off. "Teach me crowding out" gets you a Lesson that walks you through it, has you answer as you go and ends with its card.
The exam is 60 multiple-choice questions in 70 minutes, then three free-response questions in an hour, one long and two short. Most of them are chains of cause and effect, and chains are what a quiz a day trains.
A little every day
AP Macro builds on itself: Unit 5 makes no sense without Units 3 and 4. edgi makes the daily habit the easy part: one Lesson keeps your streak, a widget on your home screen shows it, every concept earns a card, cards turn foil and then gold as you come back to them, and every Set has a finish line. Your Map fills in unit by unit, and economics connects to history, psychology and politics, so you can see why it matters.
