I haven't followed up on the free program through the Joey Klein organization, but I investigated the free apps and picked one called Calm. I liked the sounds and pictures that came with it. It has a free 7 day intro program, which consists of 10-min guided meditations. Each day introduces a different meditation technique as a topic, which is helpful to a newbie, but basically, each day is a short meditation focusing on your breathing and being still. Access to more themed guided meditations open up to paid subscribers, and it sounds like more programs are introduced over time.
I completed the 7 day program in 7 days, making time to do it in the last part of the day. I like the quiet of it, because of all the bustle here at the house. I will try to tweak my timing or environment to create a better meditation space (for example, since the washer/dryer are in my bedroom, don't have them running). Regardless, I want to stick with this as a routine. My sleep became more restful. Going forward, I'll either repeat the free 7 day program, use the timed unguided meditation program (also free), or become a subscriber. It's $40/year ($39.99!), but a couple of days ago I got an email offer to sign up for $30/year.
