Chicago drivers face daily variability on the Kennedy (I-90/94), Dan Ryan, Eisenhower, and Lake Shore Drive — especially in winter weather. BoardSpy sends a push alert before your configured leave time when your saved route is slower than normal.
Pre-departure, not in-car navigation
BoardSpy answers: Should I leave 15 minutes early? It uses Google Maps traffic data and opens Google Maps for directions when you are ready. Keep your preferred navigation app for the drive itself.
