All trials might have been unique a decade ago, but it's basically just yelp for trails and there are several apps that do the same thing but better. The only major changes all trails has made in the years I've been using it is locking more and more features behind a subscription fee. I guess that's "unique". Certainly more innovative that a pocket conversational AI that I can have an realtime voice conversation with, or send pictures to to ask about real world things I'm seeing, or generating a unique image based on whatever thought pops into my imagination that I can share with others nearly instantly. Nothing interesting about that. The decade old app that collates user submitted trails and their reviews and charges 40 dollars a year to use any of its tracking features is the real game changer.
