For those folk looking for a meditation app, I highly recommend Insight Timer. I use it to time my meditation sessions and it shows your progress over time. It was motivating to see how many days in a row I had practiced and this gently encouraged me to sit for longer and longer periods of time. Plus, the social aspect has really grown on me. I feel warm and fuzzy inside when folk from across the world send a comment to thank me for meditating with them. It also has a range of free guided meditations in many different traditions – there is something for everyone.

2019 Update: A few of my guided meditations have been posted on Insight Timer! If you search for my name, they should come up.
