Your personal recipe collection — with everything that goes with it
hammhamm.app helps you collect your favorite recipes, automatically calculate nutrition values, and structure your diet clearly. GDPR-compliant, distraction-free.
Personal recipe collection
Your recipes belong to you — not a social network, not a cookbook publisher. hammhamm.app gives you a private place to collect recipes from all sources: imported from websites, scanned via photo, or entered manually.
You can sort recipes into your own groups — by category, season, occasion, or however makes sense to you. Favorites can be marked and are always quickly findable. Whether 10 or 1,000 recipes: the collection stays organized.
- Import via URL (e.g. from Einfachkochen, BBC Good Food, Allrecipes)
- Photo import via OCR: photograph the recipe, the app does the rest
- Groups and favorites for personal organization
- Share recipes with others or keep them private
Automatic nutrition analysis
The heart of hammhamm.app is automatic nutrition calculation. As soon as you add a recipe, the app matches the ingredients against the USDA FoodData Central database and OpenFoodFacts — two of the most comprehensive nutrition databases in the world.
The result: calories, proteins, fats, and carbohydrates are calculated per serving — without you having to look anything up or enter it manually. The calculation runs fully automatically in the background as soon as a recipe is imported or saved.
This makes hammhamm.app especially useful if you want to lose weight, gain weight, or simply eat more mindfully. You see at a glance how much energy a meal provides — and can choose your recipes accordingly.
- Calories, protein, fat, carbohydrates per serving
- Data source: USDA FoodData Central + OpenFoodFacts
- Fully automatic — no manual lookups
- Helpful for losing weight, gaining weight, and mindful eating
Shopping list
A shopping list can be created from any recipe with one click. hammhamm.app automatically combines ingredients from multiple recipes so you don't buy duplicates and never forget anything.
The shopping list can be shared with other people — handy for couples, families, or flatmates. Changes are signaled via push notification so everyone is always up to date.
- Auto-fill from recipes
- Combine multiple recipes
- Share with others (real-time notifications)
- Check off items — the list remembers your progress
Weekly and monthly planning
With the meal planner in hammhamm.app you can plan meals several days in advance. This gives you an overview of the whole week's nutrition and helps you eat balanced without having to think about it every day.
A shopping list can be generated directly from the meal plan — you see exactly what you need for the planned meals and shop accordingly. No detours, no duplicate work.
- Weekly view: assign meals by day
- Monthly view for longer-term planning
- Create shopping list directly from the plan
- Nutrition overview for the entire period
