Well worth it! Consider it your Dana (donation)
I’ve started using this app for a couple of months now for about 2 hours daily. After taking the 10 day Goenka course almost a year ago , I’m still not feeling much sensations or feel I might not be doing it correctly. The app is very useful in keeping your mind focused in whatever topic you choose to do at that moment and the instructions are much clearer in helping you to understand what it is you’re supposed to do. I would never have imagined I’d be able to feel sensations all over but also to penetrate inside the body without this app. I wished I knew about this app right after my course. The only thing I find that might help is to have a few minutes at the beginning of each topic to settle down the mind or breath.
