KalApp is a calorie and nutrition tracker for people who want to know exactly where every number comes from. YOUR OWN CATALOGUE • Create foods from the package label — exact values, your units, your names. • Build recipes by weight. Per-100 g and per-serving values are calculated for you. • Log restaurant meals by dish, with your own estimate — clearly marked as an estimate. • Search results are grouped by source — your own foods, the community database, generic foods (USDA) and online products (Open Food Facts) — so you always see where a value came from. FAST LOGGING • Meal slots for the day, quick-add of your most used items, barcode scanning. • Water tracker, history calendar, weight and trend charts, streaks. • Export of your history as PDF or CSV. • Apple Health: writes weight and nutrition to Health if you allow it, and reads active energy for the day's balance. YOUR DATA • Your log and your catalogue live on your device and in your own iCloud. No account, no login, no server of ours holding your diary. • Share a food or recipe with family by link — AirDrop, Messages, whatever you use. Links expire after 72 hours. • Send a food, recipe or restaurant dish to the community if you want to. Every submission is reviewed before it is published, and your original stays yours. FREE • No ads, no subscription, nothing locked. CZECH AND ENGLISH • Fully bilingual, including the food database. IMPORTANT — PLEASE READ KalApp is a logging tool, not a medical device, and it does not provide medical, dietary or nutritional advice. Nutrition values come from public databases, community submissions and your own entries and may be inaccurate, outdated or incomplete. Calorie and macronutrient targets are estimates based on general formulas and may not be right for you. Use the app at your own risk. Consult a doctor or a registered dietitian before changing your diet, especially if you are pregnant or breastfeeding, have a medical condition, a history of disordered eating, or take medication. If you are unwell, seek medical help; do not rely on this app. The app is intended for adults. Support and privacy: kalapp.cz
