GreenFin

Personal finance across currencies, in one place.

Personal finance tools tend to assume one currency and a bank they can connect to. Neither assumption survives contact with holding money in Naira and something else at the same time.

GreenFin tracks accounts, goals, bills and investments across currencies, with Naira as the primary view. Entry is manual by design: there is no bank integration, so no banking credentials are ever handed to it.

It was built as a single-user application, and access is limited to allowlisted accounts.

The GreenFin dashboard: total net worth in Naira with a seven-day trend, a liquidity breakdown splitting the total across current, business, savings, investments and pension, and summary cards counting accounts, goals and bills. — Net worth across every account, split by how quickly you could actually reach the money. Figures and institutions here are invented.

GreenFin account balances grouped by type — current, business, savings, investments and pension — each row naming the account, the institution and the balance, with one account held in US dollars. — Accounts grouped by type, with foreign-currency holdings sitting alongside Naira rather than converted away. Figures and institutions here are invented.

The GreenFin bills view: how much of this month is paid against the total, the remainder, next month’s estimate and the annual commitment, then a list of bills due in the next fortnight with the account each is paid from. — Bills for the month, with what is left to pay and which account each one comes out of. Figures, institutions and bill names here are invented.

GreenFin Portfolio Companion

Reads Nigerian stock prices from investing.com and writes them into your GreenFin investment portfolio, so valuations stay current without typing prices in by hand. More price sources may follow.

Requires a GreenFin account — it updates a portfolio rather than creating one.
