Kulhydrattælleren is an educational app designed for iPhone users, focusing on carbohydrate counting for better dietary management. It features a database of over 500 food and drink items, providing detailed information on carbohydrates, energy, protein, fats, sugars, and dietary fiber. Users can easily navigate through categories or search for specific items, making it accessible for anyone tracking their intake.

The app offers additional functionalities through a user profile, allowing for personalized meal creation, sharing of food items and meal plans, and the ability to save notes on individual food experiences. Users can adjust portion sizes and have their custom entries synced across devices. While the basic features are available without a profile, creating one unlocks a more tailored experience for managing dietary needs.
