Parknav is a free iPhone application developed by AI Incube Inc. under the Travel & Navigation category. It aims to assist drivers in saving time by providing real-time street parking availability for free, metered, or permit parking in the US and Germany.

The app works by allowing users to select the type of street parking they seek and then displays real-time open street parking within their immediate area through a color-coded street grid, where green indicates a high chance of finding parking, orange denotes a fair chance, and red signifies a low chance. Users can also benefit from features like the "Best parking route" for optimal driving routes, "Save car location," "Walk to car," and more.
