Don't buy the bundles - they will NOT be UPDATED – Brain Power | AmbiScience™ • Binaural & Isochronic Ambient Mind Utility Review

I asked several times to have the "Zen Master" bundle that has nice tones and features to be updated to be consistent with the presets and other nice upgrades that the main app has and it has STILL NOT HAPPENED. Overall, the app is good and I'm an almost daily user. They just really let me down with the failure to update the bundle, even when specifically asked. I have tried a few others and think this is the best of breed.
