About this app

pheLena helps people with phenylketonuria (PKU) manage their daily phenylalanine intake (PHE) easily, accurately, and safely. Instead of complicated calculations or generic nutrition trackers, pheLena provides exactly the features that people with PKU and their families need in everyday life: a PHE diary, barcode scanner, blood level history, recipes, and a curated PKU database.

FEATURES
• PHE diary: Search for foods, enter the amount, and automatically calculate the PHE values against the daily limit — including breakfast, lunch, dinner, and snacks.
• Blood level history: Record blood PHE levels, track them in charts, and keep an eye on the target ranges.
• PHE calculator: Quickly calculate the PHE value of individual products — ideal when shopping or eating at a restaurant.
• Barcode scanner: Scan the EAN code and add products directly from the database or link them again.
• Recipes: Save your own recipes and automatically calculate the PHE value per serving.
• Offline mode: Entries can also be made without an internet connection and are automatically synchronized later.

PKU DATABASE
More than 2,500 products with PHE, calorie, and nutritional information. The database also includes many special low-protein products for people with PKU.
