Haha I am realizing that now. It does indeed sound like a totally fluke argument, but what I can assure you is that Apps I've used require $10/month subscription and that I think is excessive. Get a book, read it once, and sell it off and you have all the knowledge and understanding of mindfulness for life. It is not like a C++ reference book that I need to pull off every other day for reference. It is a technique which once you learn, its cemented and you don't need anything else forever!
