Key App | 84 followers on LinkedIn. Our mission is to provide instant and affordable money transfers globally. | We developed Key App in response to the high-fee, slow, and inconvenient money transfer services currently available. According to the World Bank's report "Remittance Prices Worldwide Quarterly," people pay an average of 6% for sending money. These fees are paid by hard-working individuals who send money to their friends, support their families, and cover their parents' treatment costs.
