Ghent Audio Guide
Read full descriptionHide full description
Walk medieval Ghent in eight stops, from the old grain market to the counts' fortress. Hear why the city built a bell tower taller than its cathedral, how the van Eyck brothers' altarpiece survived looting, the Nazis and a still-unsolved 1934 theft, and why the prettiest quay in Flanders is really a receipt for the wool trade. Two narrators, real history, and a route you can walk at your own pace. Audio plays offline once downloaded.

Verdict
The clearest difference is update cadence: Ghent Audio Guide at every 5 days against OBDLink's every 2 months. OBDLink's advantage is chart position (#178 vs unranked) and device support (3 vs 1). On price, ads and in-app purchases there is nothing between them.
