De Week is an informative Android app developed by Barbara Martens that provides a comprehensive guide to your stay in Costa Blanca. The app covers a range of categories, including local news, cultural events, walking trails, day trips, restaurants, markets, and much more. The best part is that most of the listings come with GPS locations, directions, and direct calling functions, making it easy to navigate and explore the region.

Apart from the listings, the app also features advertisements from local businesses offering their services, giving users a chance to discover new places and experiences. The app is regularly updated with new information and expanded listings, making it an excellent resource for anyone visiting Costa Blanca.
