These are a great idea!
These are a great idea! It's almost like walking around, at your own pace, with your own 1:1 guide. You can stop, pause, rewind, fwd as you desire. The app uses your smart phone's GPS and magically guides you with a variety of turn left, turn right here instructions. Lots of info, photos and a route map. We've done the Cadiz and Jerez tours. Looking forward to Bruges in November. Well worth the money!
