Digital maps stepped in the shoes of paper maps today as they provide detailed relevant information without need of carrying kilometers of paper in the pocket. Still online maps require Internet connection and users are limited by their data plans. The best solution when you want to travel around the country without fear of paying a fortune to cellular provider is to use GPS with offline map support.
Certain GPS app providers propose a possibility to use pre-downloaded maps for offline use. So when you use the app, the device will use built-in GPS and a map stored in the phone.
Here are the best apps of the market of offline GPS systems:
Sygic GPS Navigation. Though the app is considered to be free, the world map costs $50. Before you start using the app you will have to select necessary countries and download maps. The search system of the app requires full address of the destination point – city, street and house number before it will start searching. Be prepared for slow searching, though it will work without Internet connection. 3D display is preferable for driving as it is more user-friendly. Audio notifications are annoying, though voice navigation is helpful and accurate. One of the paid additional features- celebrity voices for navigation including voice of Homer Simpson.
Navmii is a free app that is great to use as here almost everything is free (national map packs are exception – under $5 each). The app is available on major mobile platforms and there are some differences of usage: Android users get a single app with a whole world map and Apple users have to select certain regional option. The app is easy to use, fast and well-designed. And try some add-ons: be guided by the voice of Snoop Dog.
CoPilot Premium. This app is commercial – even free version of it requires additional fee for every extra feature, no matter how small is it. The distinctive feature of CoPilot is that the app splits the map of the U.S. regionally, not by state. POI search system is categorized and you have to pick the category first before searching the keyword. The app also proposes a possibility to browse through Google and Yelp for certain items, though this feature will not help you when you use the app in the offline mode. Search system is bamboozling and requires ZIP code of the city first.
