Protein Hunter is a protein and nutrition app with a database of 232 foods — from a leaf of kale to a wagyu steak — plus AI tools that answer protein questions, count a whole meal, build recipes to a macro target, and track what you actually eat.
- Search any food
- Count a full meal
- Recipes to your macros
- Scan a plate or label
Why it's different: the numbers are calculated from a fixed ingredient database rather than guessed, and when a target is not physically achievable the app says so instead of inventing a figure.
