From iBreviary.org:

The iBreviary is your portable breviary. You can use it to pray with the full texts of the Liturgy of the Hours. Simply use the live feed on this webpage or download the iBreviary app for your phone or tablet, and all the texts of the day will appear before you just as they appear in the printed version.

The iBreviary also offers you the complete daily missal to follow the Mass, daily readings and all the major Catholic prayers and more!
