From Zen Mandolin:
iGongyo is an elegant app that will get you to chant quickly and without resistance. No confusing options to configure before you begin chanting. Simply start the application and begin your practice. Just double click to return to the Butsodan. Chants kindle the spiritual energies within us. They make a positive effect on our mind and heart and bring us nearer to our souls. iGongyo will help you begin your practice or continue it without hesitation. iGongyo will help you build your confidence in chanting. No need to chant alone at home or when traveling. Simply start the app and your iPhone will be transported into a Buddhist shrine where you can gaze upon an inspiring Gohonzon and hear the voice of prayer. You can chant Daimoku or Gongyo with a group as you view the Gohonzon. NAM MYOHO RENGE KYO! Translated:
NAM = DEVOTION MYOHO = MYSTIC LAW; MYO=TO REVIVE /RETURN TO LIFE/TO OPEN/TO ENDOW; HO=DEATH RENGE = LOTUS FLOWER*, SIMULTANEITY OF CAUSE AND EFFECT KYO = SOUND, VIBRATION, TEACHING, SUTRA
