My friend Simon release his app called Peregrine this week. From the description:
"Pick a starting point and an end point – Paris to Berlin, Mumbai to Kathmandu, Vancouver to Mexico City, or anywhere else – and walk the journey with your own steps. Every day, you'll see a new photo taken at the place you've virtually reached."
iOS only, get it here: https://itunes.apple.com/dk/app/peregrine-journey/id1430790121?mt=8
