Numi Understand your body. Not just your calories.

Numi uses a combination of computer vision and large language models trained on a broad food dataset. It handles home-cooked meals, restaurant dishes, mixed plates, snacks, and drinks well. Complex multi-component meals are broken down by estimated portion. The more you use Numi, the more context it has about your eating patterns, which improves the relevance of its guidance — even when raw recognition has some uncertainty.

Traditional trackers are databases — you search, log, and count. Numi skips all of that. There's no manual entry, no barcode scanning, no searching a food library. You just take a photo. More importantly, Numi is not just a logger — it's an intelligence layer that interprets your data. Instead of showing you that you hit 2,000 calories, it tells you whether that was a high-quality day for your specific body, what your energy patterns suggest, and what to prioritize next.

Yes — that's the core design principle. Open the app, point your camera, done. No typing, no searching databases, no weighing food. Numi is built around the idea that the less friction between eating and understanding, the more likely you are to build a sustainable habit. You can add notes or adjust portion sizes if you want precision, but the default experience requires zero manual entry.

Numi uses the Mifflin-St Jeor equation to calculate your Basal Metabolic Rate (BMR) — the calories your body burns at rest — based on your age, weight, height, and sex. This is multiplied by an activity factor (1.2 to 1.9) to get your Total Daily Energy Expenditure (TDEE). From there, Numi sets a safe calorie target based on your goal (loss, maintenance, or performance) and optimizes your macro split — typically around 30% protein, 40% carbs, 30% fat — adjusted for how you actually eat.

Your data belongs to you. Numi does not sell your personal or health information and does not share it with advertisers. When you scan a meal, the photo is sent to our AI provider (OpenAI) to work out the nutrition, and it is also saved to your own private storage area so the meal shows up in your history on every device you use. We strip GPS metadata before upload, and we never use your photos or logs to train AI models. Deleting a meal deletes its photo; deleting your account deletes everything. Full details are in our Privacy Policy.

Numi is designed to support sustainable weight management through awareness and better decision-making — not crash diets or extreme restriction. It creates a moderate, safe caloric deficit (typically 200–400 kcal/day) that targets roughly 0.3–0.5 kg of loss per week, which preserves muscle and keeps your metabolism healthy. The goal isn't a number on a scale — it's understanding your body well enough that better choices become natural over time.

Numi is free to download and gives you 5 AI meal scans every day at no charge — no credit card, no trial countdown. Numi Pro is an optional auto-renewing subscription that removes the daily scan limit and unlocks the full Progress and Weekly Report features. Lengths and prices are shown in the app before you buy, payment is charged to your Apple Account at confirmation, and the subscription renews automatically unless you cancel at least 24 hours before the period ends. Cancel any time in Settings → [your name] → Subscriptions. See § 5 of our Terms of Use for the full terms.

Yes. Numi uses a multi-model AI pipeline: computer vision to identify food from photos, a nutritional reasoning layer to calculate macros and glycemic impact, and a large language model to generate personalized, context-aware insights. The system also references structured food databases (including USDA FDC data) for nutritional grounding. Over time, the Body Engine layer builds a personal model of your patterns — it's not just a generic AI response, it's one that knows your history.

Numi is a wellness and nutrition awareness tool, not a medical device. It is not intended to diagnose, treat, or manage any health condition, including diabetes, eating disorders, or metabolic diseases. If you have a specific health condition or dietary requirement, please consult a qualified healthcare professional before using Numi or making changes to your diet based on its guidance.

Numi is an AI calorie tracker built specifically for iPhone that uses computer vision to identify food from a photo and automatically calculate calories, macros, and glycemic impact. Unlike traditional calorie trackers that require manual logging or barcode scanning, Numi eliminates data entry entirely — you point your camera and get instant nutrition analysis.

Numi is a modern AI-powered alternative to MyFitnessPal. Where MyFitnessPal requires you to search a database and log each food manually, Numi uses photo recognition to identify meals automatically. It also adds personalized insights and glycemic impact tracking that MyFitnessPal does not offer. Free to download, with no ads.

Yes. Numi is a calorie tracker for iPhone that eliminates manual logging entirely. Instead of searching a food database or scanning barcodes, you point your camera at any meal and AI computes calories, macros, and glycemic impact in seconds. It works for home-cooked food, restaurant meals, snacks, and drinks.

Yes. Numi estimates portion sizes and macros (protein, carbs, fat) directly from a photo using computer vision and a nutritional reasoning model. No food scale, weighing, or manual portion entry required. Accuracy improves as the app learns your typical portion sizes over time.
