NutriOn makes calorie tracking, food logging and everyday nutrition easier. Snap a meal photo, explore your calorie and macro estimates, and get AI nutrition guidance for your next meal. Whether you are working toward weight loss, maintaining your weight or building better food habits, bring your food diary, meal ideas and nutrition tracker together. PHOTO FOOD TRACKER Turn a meal photo into a starting point for calorie tracking. NutriOn estimates the food, portion size, calorie content and macro breakdown, so you can spend less time entering each meal. Use your food tracker for home cooking, restaurant food, snacks and everyday meals. Photo estimates are a guide, not exact measurements: review the food and portions to keep your nutrition tracking useful. CALORIE TRACKING THAT FITS YOUR DAY See how each meal contributes to your daily calorie goal. Your calorie tracker puts meal information and food choices in context, helping you understand your day beyond a single number. Use calorie tracking to support a weight loss goal or weight maintenance routine. MACRO AND NUTRITION INSIGHTS Look beyond calorie totals with protein, carb and fat estimates. Your macro tracker brings macro information into the same food diary as your calorie tracking. Explore available nutrition details, including sugar and fiber, to understand more about the food on your plate. Compare your meal choices with your goals and use nutrition tracking to build awareness of your usual eating patterns. YOUR AI NUTRITION COACH Turn food tracking into practical meal guidance. The AI nutrition coach uses your logged food, goals and preferences to suggest what to consider next. Ask follow-up questions about meal choices and explore suggestions that fit your routine. Nutrition guidance helps connect calorie tracking, macro tracking and meal planning without making every food decision feel like homework. PERSONALIZED RECIPES AND MEAL IDEAS Find meal inspiration with ingredient portions and nutrition details. Explore recipe suggestions around your preferences and the ingredients you have. Bring your calorie goal and macro goals into meal planning, then use your food tracker to review what you ate. Your nutrition tracker and recipe ideas work together to help make the next meal easier to plan. WEIGHT GOALS, EVERYDAY HABITS Use a calorie tracker as one tool in your weight loss or weight maintenance routine. Food tracking can help you notice patterns; nutrition tracking can help you reflect on choices. Weight loss is individual, and NutriOn does not promise a specific weight change. Keep your health needs in mind and choose a pace that fits your life. A food tracker supports awareness, not a judgment about you or your meal. PROGRESS WITH ENCOURAGEMENT Review your food diary, calorie progress and macro information over time. Build a meal logging routine with streaks and encouraging feedback from Appi. Let your nutrition tracker help you return to regular tracking after a busy day. Small food habits can be easier to maintain than an all-or-nothing diet or a rigid weight loss plan. FROM ONE MEAL TO THE NEXT • Photograph your food and review the calorie estimate. • Explore your meal's macro and nutrition details. • Look at daily calorie tracking alongside your goals. • Ask the nutrition coach about your next food choice. • Find a recipe and return to your food tracker tomorrow. Make room for health, enjoyment and everyday food. Start your calorie tracking and nutrition tracking routine with NutriOn. Some features require a paid subscription. Check the in-app offer for current access and subscription terms. Nutrition and calorie estimates are for general wellness and personal tracking, not medical advice, diagnosis or treatment. For health concerns or major diet and weight loss changes, consult a qualified health professional.

Verdict
The clearest difference is rating: NutriOn at 5.0 against Calorie Tracker's 4.7. NutriOn also leads on update cadence (every 3 days vs weekly) and device support (3 vs 1). Calorie Tracker's advantage is ratings volume (15 vs 1). 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. Calorie Tracker sells 2 in-app purchases, starting at $2.99 per 7 days and NutriOn sells 5 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
NutriOn holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Calorie Tracker has 15 ratings behind it against 1, so its average is the more settled of the two.
Calorie Tracker ships an update weekly, NutriOn every 3 days. The most recent releases landed on November 5, 2026 and October 30, 2026 respectively.
