I strongly recommend this site. Based on the Daily Examen of the Spiritual Exercises of St. Ignatius, It offers a variety of types of examen, including Old and New Testament, Psalms, Regular, etc. following the format of the Exercises: Presence, Praise, Process, Penance, Promise. It also has different reading programs from a week to a year long. Very gentle, very non-intrusive, user-friendly.
