It seems that a big part of the value prop is that 1) it assumes there is some connection in terms of feelings experienced among people born on the same day (essentially a higher-fidelity astrology) and 2) that if you live in a later time zone, you can find out what is coming next by viewing the feelings of those in an earlier time zone. If one assumes that #1 has some truth to it, one has to wonder what will cause people in earlier time zones to use the app, since they don't get to take advantage of #2.
