Scout: Maps GPS Navigation is a free app developed by Telenav Inc. for iPhone users. It is a personal driving assistant and copilot that helps you navigate faster, easier, and safer. The app offers turn-by-turn GPS voice directions, real-time traffic and live speed updates, and the most up-to-date map information powered by OpenStreetMap (OSM).

With Scout, you can discover new places to dine, shop, walk, get gas, and more. You can also share your ETA with your friends and family in a single tap. The app allows you to customize your route preferences, favorite map views, and schedule personalized commute departure alerts for home and work. Additionally, Scout provides you with driving behavior insights to help you learn more about your habits and understand your driving behavior.

However, it is important to note that Scout's map and search coverage are currently only available for the USA. Also, continued use of GPS running in the background can decrease battery life. Overall, Scout: Maps GPS Navigation is a great app for those who want a reliable and easy-to-use navigation tool with additional features to make their driving experience safer and more enjoyable.
