The macro companion to PlainMoney.
Exchange rates and central-bank decisions as they happen. The gold standard to Bretton Woods to today's floating-fiat system — and the alternatives: hawala, mobile money, stablecoins, CBDCs. Formal models and the literature graduate finance programs assign. One body of content, three depth layers, every claim traced to the IMF, World Bank, BIS or a central bank — never a headline.
Both apps are in review with Apple and Google — launching soon.
Real screens from the app — search or ask in plain language, then drill into Applied practice and Research literature without ever losing your place.
The same topic page serves a curious reader, a working professional, and a graduate researcher. No tab is ever labeled by who you are — only by how deep the content underneath it goes.
The plain-language explanation, why it matters to your own finances, and the two or three sources that back it — always free, no account needed.
How practitioners and policymakers actually use it, live data where an official series exists, the governing documents, and worked examples.
Derivations, the empirical literature, data methodology, open debates — the readings a graduate finance program actually assigns.
Pro is one subscription, $9.99/month, no free trial — it unlocks Applied and Research on every page in the app. What's included →
For the general public, working professionals and policymakers, and graduate students and faculty — one body of content, never a simplified spin-off.
Exchange rates, policy rates, and inflation prints — refreshed on demand from the IMF, World Bank, BIS, ECB and national central banks. Keyless, official APIs only.
Citations are tappable and open in-app at full width, 85% height, and return you to exactly where you were. Never a bare footnote.
Barter to the classical gold standard, Bretton Woods to the floating era — plus hawala, mobile money, community currencies, stablecoins, DeFi and CBDCs.
An on-device AI answers questions grounded in the app's own sourced pages and names exactly which pages it used. Nothing you ask ever leaves your phone.
App onlyMechanisms, cause-and-effect chains, and what has historically followed — never a tip on what to buy, sell, or invest in.
No accounts, no bank linking, no ads, no analytics. The only network activity is data you ask it to refresh and citations you tap.
All 359 pages ship with the app. Read the full monetary history of the world on a plane, with zero connectivity.
Formal models, the empirical literature, and data methodology — deep enough for a graduate finance program, not a summary of one.
