I have a lot of prayers on my iPhone, including my Magnificat magazine. I also have an app. that reminds me when it's time to pray the Angelus. I like these prayers for a couple of reasons. One, they connect me to the universal Church. Two, they are habit-forming, and three, I think they are good "warm-ups" to having more intimate conversations with God.
I do pray "off the cuff" - those little moments when I thank God, or ask for favor or grace, either for myself or someone else.
How do you like to pray?
