I really like this app... I've used it consistently and read it almost everyday for the last 6 years. It used to be my favorite tool for personal insight but the recent updates make me feel like it's skimping on anything related to self. there is way more to read about others than there is to read about self and ive got to say that it's incredibly disappointing and although the insight on others is good. I find myself reading less as my purpose for being there is to navigate my own path.

Agree with other's posts. I have had this app for a while and a lot of the info that was free is no longer and there's barely any info that is available without paying for it. If you added new aspects and charged for those that might make sense but to take away what we already had access to has made this app unusable and honestly the greed makes it repulsive, Thanks but no thanks. Ya'll were awesome at one point and now...well, you've made it easy to delete.

Bad update! The You page is practically completely gone and that was honestly the best part of the app. They tried to add the You section information to the home page (sort of) but now I'm noticing that the information there is so superficial (and kind of weird honestly) and not very accurate at all. The new blurbs feel like weird stuff an AI would come up. Edit 1: they changed it back to how it was and that was great Edit 2: went back to the previous update that I wrote a negative review for
