Snap your meal or describe it in plain English — Fun Diet Lab’s AI logs the calories, protein, carbs, and fat in seconds.
Point your camera at your plate and get an instant calorie estimate — restaurants included.
Type “two eggs, toast, and coffee” and three entries appear with full macros.
Photograph what’s in your fridge and get recipe ideas sized to your goal.
Scan a restaurant menu and see the smartest dish for your remaining budget.
Tell it “I want pizza” and get honest options: a lighter recipe, a smart swap, or a portion trick.
Paste any blog or video link and get a version rewritten to fit your calorie target.
Calorie targets use the Mifflin-St Jeor equation — the standard dietitians rely on. AI estimates are cross-checked against the USDA FoodData Central database, so the numbers are grounded in food science, not guesses. Works offline, syncs when you reconnect, and integrates with Apple Health.
