A running app that routes you through shade when it is hot
Route planners optimise for distance and elevation. In summer, whether you are in the sun decides if the run is bearable.
Build a route planner that takes a distance, a start point, and a time of day, then returns a route that keeps you in shade.
Tree canopy data, building heights, and sun position at that hour are all available. Nobody has combined them into a route.
The same thing works in reverse in winter, and for walking rather than running.
Launch in one city and make it correct there. People will notice on the first run whether it worked.
