Questions

Before you start.

What to expect from photo estimates, the free plan and your data.

How accurate are photo calorie estimates?

A photo gives you an estimate, not a measurement. Clearly visible foods are easier to recognise; cooking oil, sauces and hidden ingredients are harder to see. Review the recognised foods and estimated portions before tapping Log Meal. For packaged food, you can scan a barcode instead.

What does Numi cost?

Numi is free to download, with 5 AI meal scans each day. Numi Pro is an optional auto-renewing subscription with unlimited AI scans and the full Progress and Weekly Report features. Prices and subscription terms are shown in the app before purchase. You can manage or cancel your subscription in your Apple Account settings. See our Terms of Use.

Is my food and health data private?

Numi does not sell your personal or health information or share it with advertisers. Meal photos are sent to OpenAI for analysis and saved privately with your meal history. GPS metadata is removed before upload. Numi does not use meal photos or food logs to train AI models. See our Privacy Policy for storage, processing and deletion details.

How does Apple Health sharing work?

You choose which Apple Health permissions to allow. With those permissions, Numi can share logged energy, nutrients, water and weight with Health and read supported health information. Manage access in Apple Health. Numi’s Apple Health setting opens Health when connected. Read the Apple Health setup guide.

Which devices and languages does Numi support?

Numi is built for iPhone and requires iOS 18 or later. It is available in English, Russian and Ukrainian. Widget sizes, Live Activities and other system features depend on your device and iOS version. Check the App Store listing for current compatibility.

Do I have to type every meal?

No. Take a photo, scan a barcode or describe a meal in words. Numi proposes the foods and nutrition, then you review the result and tap Log Meal to add it to your day. Saved meals and favourites make repeat logging quicker.

How are my calorie and macro targets set?

Numi estimates your calorie needs from your age, height, weight, sex, activity and goal. Protein targets also account for body weight and your chosen pace; carbs and fat use the remaining energy. These are estimates you can review. Adaptive maintenance is a trend insight based on intake and weight history; it does not automatically rewrite your daily targets.

Does Numi support intermittent fasting?

Yes. Choose an eating window to follow your fasting and eating times in the app. A Lock Screen Live Activity can keep the timing visible. Any fasting stages shown are based on elapsed time; they do not measure what is happening inside your body.

When is a Weekly Report available?

Weekly Report is a Numi Pro feature and needs enough logged meals to produce a useful summary. Progress also uses your available food and weight history, so insights change as you build a record.

What is Numi?

Numi is an independent iPhone app for photo food logging, calorie and macro tracking, fasting windows, hydration and weight tracking. On the App Store it is called Numi — Eat with clarity.

Is Numi a medical app?

Numi is a wellness and nutrition awareness tool, not a medical device. It does not diagnose, treat or manage health conditions or measure blood sugar, ketones or metabolism. For a health condition or a specific dietary requirement, speak to a qualified healthcare professional.

Is this NuMi by Nutrisystem?

No. Numi at getnumi.app is an independent iPhone app. It is not affiliated with Nutrisystem, Numi Organic Tea or the Numi calculator for Mac.
