TUNA: Ultimate Nutrition App

About the startup

TUNA is a nutrition tracking application that monitors every micronutrient in your diet. While most trackers focus on basic calories and macros, TUNA provides detailed data on the specific vitamins and minerals within your food for a more complete understanding of your nutritional intake, while taking into account workouts, sleep, bloodwork, supplements, and for women: cycles, pregnancy, and postpartum with detail. With meal scores and user stats, TUNA creates a unique and fun, gamified user experience so logging meals becomes rewarding. Most food trackers stop at “how much did you eat?” TUNA goes deeper: it connects meals, nutrients, workouts, sleep, steps, bloodwork, and life stage data to give users a more complete picture of their nutrition status and what to improve next. Key features: TUNA tracks 100+ nutrients, including vitamins, minerals, amino acids, fatty acids, electrolytes, fiber, and more. Users can log meals with text or photos, review nutrient gaps, see macro and micronutrient breakdowns, and understand how individual foods contribute to their overall nutrition. The app is designed for people who want more than calorie counting: athletes, biohackers, women tracking cycle/pregnancy/postpartum needs, people optimizing bloodwork, and anyone trying to connect how they eat with how they feel and perform. TUNA also integrates lifestyle inputs like workouts, sleep, steps, pregnancy, breastfeeding, and bloodwork, so recommendations can adapt to the user’s real context instead of assuming everyone has the same needs every day. What makes TUNA different: TUNA is not just a food diary. It is built around nutrient intelligence. Instead of only saying “you ate 120g protein” or “you went over calories,” TUNA helps answer better questions: “Am I getting enough magnesium, potassium, choline, iodine, DHA, iron, zinc, B vitamins, fiber, and electrolytes?” “Are my meals supporting my workouts, recovery, sleep, hormones, and bloodwork?” “What nutrients am I consistently missing?” “Which foods give me the biggest nutritional return?” TUNA is also built with women’s physiology in mind. Nutrient needs change across menstruation, pregnancy, postpartum, and breastfeeding, but most nutrition apps treat users as static. TUNA is designed to adapt as the user’s body and goals change. It also brings together nutrition, performance, and health data in one place. Instead of having meals in one app, workouts in another, sleep somewhere else, and bloodwork in a PDF, TUNA helps users connect the dots. Real outcomes users can expect: Users can expect to become much more aware of their true nutrient intake, not just their calories. Within the first few days, they can identify obvious gaps in their diet, spot foods that are doing a lot of nutritional work, and understand where their meals may be falling short. Over time, users can build better meals, improve consistency, support training and recovery, make smarter supplement decisions, and personalize their nutrition based on actual patterns instead of guessing. TUNA is especially useful for people who already care about health but feel like existing trackers are too shallow. It gives them a clearer, more data-rich way to optimize nutrition without reducing food to just calories. TUNA helps users eat with more precision, adapt nutrition to their life, and turn messy health data into actionable insight.
