On my Android OS, these are apps I can’t live without:
Saint A Day: While there are other apps around saints, Saint A Day have the stories nicely summarized with most relevant facts, easy to digest daily in the morning. I use it everyday.
Laudate. Probably the most complete app. It is where I learnt to play the rosary by myself, there are some nice and interactive rosaries. Also full of prayers, reading of the day, reflections, catechism, station of the cross, liturgy of the hours, … it is a kind of overwhelming app because you can find everything there
Confesion: A Roman Catholic App Good to exam of conscience and remember last confession date.
iBreviary: Because of Laudate I never gave a chance to this app. However, it is more compact and focused, and it appears to have better usability and user experience than Laudate. I shall give a try.
