Loving it mostly, I feel now I'm reaching my limits in many areas, and wonder if I really want to pursue this as a daily event. Update: I paid for a year's worth, and just cancelled after a couple of months use. This game / learning app can be very stressful at times. To achieve high scores in certain training modules you have to answer certain questions within a limited time, this time pressure can be very stressful. For this reason I've cancelled my subscription and deleted the app.
