NutriSnap

Snap a photo of your meal to log its calories and nutrients, track the calories you burn with Apple Health, and follow a personal plan for your goal — on iPhone and iPad. Version 1.3

What it does

NutriSnap makes food tracking fast. Point your camera at a meal and it identifies the food on your device and suggests matches — pick one, set the amount, and it's logged with calories, protein, carbs, fat and more. It reads the energy you burn from Apple Health, so you always see calories in and out, and it builds calorie and nutrient targets around your goal: losing weight, maintaining, gaining, or building muscle.

How to use it

• Set your goal. On first launch, choose your goal and enter your sex, age, height, weight and activity level (or import them from Apple Health). NutriSnap calculates a daily calorie and macro target for you.
• Snap a meal. Open the Scan tab and take a photo — NutriSnap finds each food on the plate on-device and suggests matches (always an estimate you confirm). Pick a real household portion ("1 cup", "1 slice"), or use the no-scale portion guide.
• Scan a barcode. Point at a product's barcode to look up its nutrition from Open Food Facts — free for everyone, no daily limit. Product data © Open Food Facts contributors (ODbL).
• Or search. Search 13,000+ foods from USDA FoodData Central with real portion weights, re-log recent meals in one tap, copy yesterday's meals, or create a custom food.
• Understand your sleep. The Sleep page pairs your food log with the sleep Apple Health records — see whether late dinners, afternoon caffeine, or evening alcohol line up with shorter nights, plus sleep debt, schedule consistency, and overnight vitals. Computed on your device, with published sources cited in the app.
• Balance your training. The Activity page shows your rings and workouts next to what you ate — calories in vs out on one screen, and whether you fueled with protein after training.
• See your day. The Today screen shows calories remaining, your macros, the calories you've burned, your meals and your weight trend at a glance.
• Get coaching. The Coach tab turns your day into personal tips — what to eat to hit your protein, or a quick walk to balance an over-budget day.

Apple Health

NutriSnap works best with Apple Health, but it's optional. When you connect it:

• It reads your active and resting energy, steps, exercise, workouts, activity rings, sleep, and overnight vitals so the app can show the calories you burn, your training pattern, and how your diet relates to your sleep — all computed on your device, never uploaded, and never shown alongside advertising.
• It reads your body measurements (weight, height, age, sex) — only to personalise your targets — if you choose to import them.
• It writes the food you log (calories, protein, carbs, fat, fiber, sugar, sodium) back to Health so your nutrition stays in one place and is available to your other apps.

You control every permission in Settings → Health → Data Access & Devices → NutriSnap, and you can turn the "add burned calories" and "write food to Health" options off in the app's Profile tab at any time. Your health data stays on your device and in Apple Health — it is never sent to us.

How accurate is photo recognition?

Food recognition runs entirely on your device and is meant as a fast starting point, not a lab measurement. NutriSnap suggests the most likely foods and always lets you confirm or change the match and the portion before logging. For packaged foods or anything it doesn't recognise, search the database or add a custom food. Nutrition values are typical reference figures per serving and will vary with brand and recipe.

Your data & iCloud

Your food log, weight history and settings are stored on your device. If you're signed in to iCloud, they also sync through your own private iCloud so the same diary appears on your iPhone and iPad and is restored on a new device. We never see this data — it lives only in your Apple Account. Photos you scan are processed on your device and are not uploaded or saved by the app.

Goals & targets

NutriSnap estimates the calories your body needs using the Mifflin–St Jeor formula (your sex, age, height, weight and activity level), then adjusts for your goal and chosen pace. Protein, carbs and fat targets are set from your goal and bodyweight. You can fine-tune everything — or set your own calorie goal — under Profile → Adjust goal & body data.

NutriSnap Pro & the free tier

NutriSnap is free to use: unlimited manual logging and search, Apple Health sync, weight tracking, the Coach, and 3 photo scans a day (watch a short ad for 3 more). The free tier is supported by ads. NutriSnap Pro — monthly or yearly, each with a 7-day free trial for new subscribers — unlocks unlimited photo scans, the full weight-history chart ranges, and removes all ads. Subscriptions are billed by Apple, renew automatically unless cancelled at least 24 hours before the period ends, and can be managed any time from Profile → NutriSnap Pro → Manage or Cancel Subscription or in your App Store account settings. Terms of Use (EULA).

Where the numbers come from

Every calculation and Coach recommendation in NutriSnap cites its source — the Mifflin–St Jeor equation (Am J Clin Nutr, 1990), CDC and WHO guidance, the Dietary Reference Intakes, and more. Tap Sources & References on the Today screen, the Coach tab, or under Profile to read them.

FAQ

It didn't recognise my food.

Recognition works best on clear, well-lit photos of a single dish. If there's no confident match, tap Search manually and type the food, or add it as a custom food. Your choice is logged exactly the same way.

How do I cancel or switch my Pro plan?

Open Profile → NutriSnap Pro → Manage or Cancel Subscription, or go to Settings → your name → Subscriptions on your device. Cancelling stops the next renewal; you keep Pro until the end of the paid period.

I subscribed but Pro isn't active on my other device.

Open Profile → NutriSnap Pro and tap Restore Purchases on that device (signed in with the same Apple Account).

Why am I seeing ads?

Ads keep the free tier free. If you declined tracking, ads are non-personalized. NutriSnap Pro removes all ads.

The calories burned show zero.

Connect Apple Health (Profile tab or the prompt on Today) and make sure your iPhone is recording activity. On a brand-new device or simulator there may be no energy data yet. NutriSnap uses your active + resting energy when available.

Does it work on iPad?

Yes — NutriSnap is universal and your diary syncs between iPhone and iPad through your private iCloud.

My diary isn't syncing to my other device.

Both devices need to be signed in to the same iCloud account with iCloud Drive on. Open the app on each device and give it a moment to sync.

Is this medical advice?

No. NutriSnap is a general wellness and food-tracking tool, not a medical device, and its estimates are not a substitute for advice from a doctor or dietitian. If you have a medical condition or specific dietary needs, talk to a professional.
