Have used it for a while and generally accurate and easy to use, BUT recently ads are continually popping up while trying to work out my travel, sometimes when it's urgent. I'm ok with ads in apps but NOT ones that insert themselves in the normal workflow of a user trying to get something done. REALLY frustrating closing full page ads between steps when trying to find a bus. Only put them in start up, or better places in app, or after inactivity/pause timeout, or paid version. May remove :-(
