Your app idea is Centrania, the next Tune In Radio or music app. (you) It’s an app that plays calm music. Babies who hear it are gaga to sleep. (me) You could charge any price for that. (you) It helps when babies wake up and go, “weehh heh heh weeehhh.” It makes them go back to sleep. It goes like this, “ahh ah ahhh ahhh.” It makes people go, “aahhhhhhhhhh” (in relaxation).
P.S. I bought 1050 Theta tokens. Might buy you a pony one day or buy into an ecovillage community one day.
