The application offers an audio-Corona to San Michele Arcangelo:
This pious exercise was revealed by St. Michael himself, Prince of the Celestial Militia, in an apparition to the servant of God Antonia of Astonaco in Portugal. He told her he wanted to be venerated with Nine greetings corresponding to the nine Choirs of the Angels, each followed by a Pater and three Ave Maria, and finally concluded with four Pater: the first to his honor, the second to S. Gabriel, the third to S. Raffaele and the fourth to our Guardian Angel.
He also promised to those who venerated him in this way, before Holy Communion, to obtain from God that he was accompanied to Communion by an Angel from each of the nine Choirs. And to those who recite this Crown every day, he promised his assistance and that of the Angels in life and, in Purgatory, after death.


Furthermore, prayers to St. Michael the Archangel are presented why
He who honored St. Michael, says St. Bernard, will not stay in purgatory for a long time. St. Michael will use his power and will soon lead his soul into the celestial sojourn of Paradise

There is also a Chaplet to St. Michael the Archangel in suffrage of the dead because the Prince of the celestial militia, says St. Anselm, is omnipotent in Purgatory, he can give relief to the souls that the justice and holiness of the Most High keep in that dimension of 'beyond. It is indisputably recognized since the foundation of Christianity, said Cardinal St. Roberto Bellarmino, that the souls of the deceased are freed from purgatory through the intercession and ministry of the archangel St. Michael. We add to this authoritative theologian also the opinion of St. Alphonsus: St. Michael, he says, is in charge of consoling the souls in purgatory. He does not cease to assist and help them, providing them with many relief in their pains.
