First time in Edinburg, bought the £4 day pass 2 days in a row and went everywhere! The app worked seamlessly. We must have used the bus at least 10 times to different places like out to the royal yacht Brittania. The app suggests routes, tracks your progress in real time and even warns you that your stop is coming up. Brilliant! P.S instead of paying £15 for a hop on hop off, use the Lothian buses, sit upstairs at the front and just hop on and off all day. These buses go everywhere and a lot cheaper!
