Harpoon SMS

Harpoon Labs

About this app

Tired of fake Mobile Money payment screenshots? Harpoon verifies every MoMo payment the moment it lands, straight from the SMS receipt your phone already gets. No screenshots, no waiting, no second-guessing.

HOW IT WORKS
When a customer pays you via MTN MoMo, Vodafone/Telecel Cash, or AirtelTigo Money, your phone receives a confirmation SMS from the network. Harpoon reads that SMS, extracts the amount, sender, and transaction ID, and shows you the result in real time. If something looks off, a wrong amount, a wrong number, or no SMS at all, you know before the customer leaves.

USSD SHORTCUTS
Save the MoMo actions you repeat, like checking your balance or buying airtime, and run them with one tap. Harpoon fills in the menu steps for you and keeps the result in your history.

This feature uses Android's accessibility service, which is what lets Harpoon answer a USSD menu for you. It reads only the USSD screen your network shows during a shortcut you started.

WHAT YOU GET

• Wallet for unmatched payments: payments that don't match an order are held safely until you claim them

PRIVACY YOU CAN TRUST
Harpoon only reads SMS from Mobile Money providers on a server-maintained allowlist (MTN, Vodafone/Telecel, AirtelTigo). It does NOT read your personal messages, social media notifications, banking alerts, or any other SMS. The allowlist lives on our servers, so it can't be changed on the device, and you always know exactly which messages Harpoon can touch.

WHY HARPOON
Mobile Money fraud is real. Screenshots get faked. Customers fake confirmations. By the time you call the bank, they're gone. Harpoon kills that loop. If it didn't come through as a real MoMo SMS, it's not real.
