How Remittance Apps Work: Lemfi, Grey and Others, Explained

Apps like Lemfi, Grey, Sendwave and Afriex have made sending money to Nigeria feel instant. Understanding how they actually work — and where they make money — helps you pick the cheapest one for your transfer.

How the money moves

You pay in locally (a UK or US bank transfer, say); the app pools those payments, converts the currency at a rate it sets, and pays out in naira from funds it already holds in Nigeria. You rarely wait for a cross-border wire — that is why it feels instant. The dollar-to-naira rate is the engine behind the rate.

Where their rate and fee come from

• A margin on the exchange rate — the gap from the mid-market mid-market is the main cost.
• Sometimes a small flat fee on top.
• A “zero fee” app often just widens the rate margin instead.

Comparing them honestly

Don’t compare fees; compare the naira delivered for the same amount on the same day. Our send-money calculator gives you a market-based reference to measure any app against. For the fuller route comparison, see best ways to send money to Nigeria.
