I like that it has an option where if there's no internet connection then still works fine with offline mode which helps me in those times when i'm traveling without wifi/mobile data plan etc..
And also its free so whats not? nothing really dislike about spottikeep but maybe some features are missing (like how easy would be share link via text message) But overall good app! use only while travelling around town / city areas because otherwise will need mobile network coverage at least once every hour just to sync up again & get back online using WiFi hotspot -.-.
