ZeroSettle helps iOS developers keep more of what they earn. Instead of handing Apple 30% on every transaction, route eligible purchases through our web checkout and pay just 5% + 50¢. We handle everything — payment processing, tax compliance, refunds, and receipts. You stay focused on building your app.
