Alltrails: Excellent for trail finding globally, uses UGC (reviews, photos, condition reports), and offers filters for dog-friendly, kid-friendly, and some accessibility notes (stroller/wheelchair). Often talked about as the world best trail finding service.
TrailLink: Excellent resource for multi-use trails with information on length and surface type. Focusing on turning old railways into trails. (Rails to Trails program)
Our project has a deeper application than the ones mentioned above, while both of them are very useful apps, they aren’t integrating data sets like Unseen Philly. The beauty of our app is the local context to the Philly area. No other app is giving you directions to a hike via septa routes.
