Beware - may have undesired side effects

I tried this and had a migraine 15 minutes later, the first one in probably a year. It seems pretty likely that the brainwave tuner experience bought on the migraine. This is relatively new medical technology. A smart phone app is not the right place for it.

devo2.0 stinks about BrainWave Tuner-Binaural beats, v4.5
