Meet Nu-Trai Nu-Trai is an AI-powered nutrition and macro-tracking app designed for university students. It provides daily menu information for more than 350 university dining halls and helps students find, log, and plan meals that fit their nutrition goals. Unlike traditional food-tracking apps that require students to manually search a database for foods, Nu-Trai is designed to make nutrition tracking easier. Nu-Trai creates a personalized nutrition profile using your goals, activity level, dietary restrictions, food preferences, and favorite cuisines. It then recommends meals that fit your needs—whether you are eating at a university dining hall, ordering from a nearby restaurant, cooking at home, or grabbing food on the go. Personalized meal recommendations Ask Nu-Trai questions such as: - “What should I eat for dinner?” - “Where should I eat on campus?” - “What restaurant meal fits my remaining macros?” - “Do I have room for dessert?” Nu-Trai uses your personal profile, daily nutrition progress, preferences, and remaining calorie and macro targets to suggest relevant meal options. Natural-language food logging Log food by describing what you ate. For example: - “8 ounces of grilled chicken with rice and broccoli.” Nu-Trai estimates and records calories, protein, carbohydrates, and fat without requiring you to manually search through a food database. Multiple ways to log food Nu-Trai supports several food-logging methods: - Voice logging: Say what you ate. - Natural-language logging: Type a description of your meal. - Nutrition-label scanning: Take a photo of a nutrition label to record its information. Campus dining guidance At supported universities, Nu-Trai helps students explore dining hall menus and identify meals that fit their nutrition goals, food preferences, and dietary restrictions. Students can use Nu-Trai to see what is being served, decide where to eat on campus, and log dining hall meals more easily. Restaurant and everyday meal planning Nu-Trai can recommend meals from nearby restaurants and help users plan meals at home or on the go. Recommendations account for each user’s preferences, dietary restrictions, goals, and remaining daily calorie and macro targets. Built for busy lives Nu-Trai reduces the time required to plan meals and track nutrition. It is designed for university students, athletes, and other busy people who want to understand what they are eating without manually searching food databases or entering every ingredient.

Verdict
The clearest difference is review sentiment: Nu at 100% against MacroFactor's 71%. Nu also leads on rating (5.0 vs 4.8). MacroFactor's advantage is ratings volume (23K vs 19) and update cadence (every 8 days vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. MacroFactor sells 11 in-app purchases, starting at $9.99 per month and Nu sells 7 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.
Nu holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: MacroFactor has 23K ratings behind it against 19, so its average is the more settled of the two. Written reviews point the same way: 71% of MacroFactor's written reviews are positive against 100% of Nu's.
MacroFactor ships an update every 8 days, Nu every 3 weeks. The most recent releases landed on October 16, 2026 and October 5, 2026 respectively.
