Sure, you could remotely wander about a foreign city with Google Earth but you don't get any sort of feel for the local culture that way, just a superficial view of its storefronts. The Wander app instead connects you with an actual local for a guided Instagram tour.
Users first create a profile and select a guide from a list of suggestions. After you've picked a guide, the two of you exchange photos, providing a look into your respective lives through photo-based assignments. After the week is up, you have the opportunity to pick a new guide in another far-off land. [Wander via PetaPixel]
