I feel a lot of user's here are commenting without the experience of having any psychedelic trip before. I understand that you want to guide these trips into a meaningful learning experience but I couldn't think of anything worse than staring at a phone screen for 6-14 hours. The best trips are ones that you discover yourself, and not things that are guided by a blanket application. Also, music, I really wouldn't want to listen to preset meditation music, when I have access to what I love.
The best environment that you can be in when tripping is the outdoors, so this app can only really cater to the urbanites. Then again, if you are truly respectful of psychedelics, you'd plan your day accordingly so you can get yourself in the outdoors.
Before and after a trip I can see this being useful. During? Not so much. Please market this as a meditation app, and not one to be used when under the influence of psychedelics.
