Healthy Nutrition App Logo Grid

A clean matrix of 20 modern mobile app icon concepts, covering nutrition, calorie tracking, healthy eating, food recognition, and AI health tools. The background is a vibrant electric blue, complemented by soft studio lighting and subtle shadows. The icons are arranged in 4 rows and 5 columns with even spacing. Each icon is a rounded square with advanced iOS-style depth, smooth gradients, glass-like highlights, and clear 3D rendering details. The color scheme should primarily feature saturated blues, cyans, teals, whites, and lime greens, accented with small amounts of orange and yellow. It includes 20 distinct icon designs: 1) A bowl containing avocado, cereal, broccoli, and cherry tomatoes, surrounded by a camera scanning frame; 2) Four horizontally arranged nutrition bars in green, yellow, red, and blue, next to a white fork on a deep navy blue background; 3) A camera lens with a small bowl of vegetables in front; 4) A circular blue badge with text.{argument name="headline text" default="kcal"} And a green leaf overlapping at the bottom; 5) a cyan icon with text above a white bowl and two glittering symbols.{argument name="brand text" default="Ai"} 6) A glossy green apple with circuit traces and nodes, hinting at food technology AI; 7) Half an avocado in the center of a glowing scan frame; 8) A metal spoon with a blue lightning bolt symbol and curved tracing lines; 9) A segmented nutrition meter in green, orange, and red circles surrounding salmon and broccoli; 10) A divided plate containing roasted chicken, broccoli, rice, blueberries, and a small upward-rising histogram; 11) A camera lens on a white background with green leaves; 12) A glowing green apple in a scan frame with a flashing symbol; 13) A glowing circular ring in blue, green, yellow, and orange on a dark background; 14) A blue shield with a white fork in the center; 15) A yogurt or oatmeal bowl in a scan frame topped with strawberries, blueberries, and granola; 16) A dark navy blue calorie icon with text.{argument name="calorie text" default="kcal"} 17) A mint green square with a white circuit tree or branch chip pattern; 18) A healthy plate containing roasted chicken, avocado, tomato, and vegetables within a scanned frame; 19) A dark bowl filled with blueberries and white yogurt or cream, overlaid with a bright electric lightning symbol; 20) A light blue 3D cube icon with a fork and plate symbol on one side and green leaves on the other. The overall style should be highly refined, slightly futuristic, and commercially viable for App Store brand promotion. Ensure the visual language of the 20 icons is consistent, containing no additional text besides a visible short label, and presenting a sophisticated AI-generated product design aesthetic.
