Just apparently not TM. http://fortune.com/2016/03/12/meditation-mindfulness-apps/
Problem with apps if there are a lot of them (and probably many free) there actually is no money in it except for the ad placement businesses. If you have seen "Billions" on Showtime, the two principal characters practice meditation in the show and have an annoying app that tells them when the time is over. No "Jai Guru Dev." ;-)
