Bought and installed. Worked immediately after installation but then struggled to work again. Offline doesn't work well. Kids enjoyed finding owls but descriptions are not kid friendly. Probably easier to use a free map and follow owls, looking up buildings and places on smartphone.
We liked finding the owls around town but the app was useless. There's no search function for the numbered items and the descriptions were not aimed at kids. The map didn't even have the numbered items on it, only the start of each short walk.
Spent so much time trying to make it work, that did not enjoy the otherwise charming Dijon.
The app is well made, has offline mode and looks really nice. It's cheaper than the corresponding booklet that you can buy from the tourist office in Dijon. The walk is a great idea and this app an even better one. The walk is rated the best thing in Dijon on trip advisor. Kevin Shepherd obviously thought this was something other than what it clearly is.
This app is not worth paying for.
