I purchased from an online promotion. I am an iPad user and not tech savvy. Luminosity not compatible with Apple IPads because you need Adobe flash. When I inquired there's a whole bunch of steps you need to take to make it iPad friendly. Like use google chrome etc. Don't think you click a button to purchase and away we go. Can't get refund because my claim is past 30 day expire. There are other choices out there, less complicated and other more effective options for brain health.
