Radio Maria Perù, an iPhone application by RADIO MARIA E.T.S., is a multimedia program falling under the Music & Radio category. It serves as a platform for spiritual growth and evangelization, offering a unique path of conversion for its listeners. Operating on a volunteer basis, this app is dedicated to fostering a spiritual journey for its users without resorting to advertisements, relying solely on listener contributions for support.

Established on April 28, 1994, during the Feast of Saint Louis Marie de Montfort, Radio Maria Perù started its journey on Radio Santa Rosa with a one-hour daily program titled "Radio María por Radio Santa Rosa." The official formation of the Radio María Association on May 13, 1995, marked a significant milestone, becoming the first Latin American member of the World Family of Radio Maria. With 46 repeaters in Peru, this app received the apostolic blessing from Pope John Paul II in July 1995, and the support from Radio Maria Italy's president, Emanuelle Ferrario, further solidified its presence in Peru.
