Photograph your food.
Understand your nutrition.
Snap a photo of any meal and get calorie, protein, carb, fat and fiber estimates in seconds — sized to your own calibrated plate. Track water, follow a heart-healthy, diabetes-friendly or fasting plan, and get advice from a coach that knows your meals.
Chicken salad bowl
Three steps between hungry and logged
No manual gram entry. No searching a database of 30,000 foods. Just point, shoot, and adjust.
Snap or upload
Take a photo of your meal or pick one from your library. Good lighting helps but isn't required.
AI estimates instantly
You get calories, protein, carbs, fat and fiber for every detected item — plus a confidence score so you know what to double-check.
Edit & save
Swap grams for natural servings (3 eggs, 2 slices, 1.5 cups). Totals recalculate instantly. Save to your journal and your streak keeps going.
Built for people who actually eat food
Not a spreadsheet. Not a diet. A quiet daily habit that adds up.
Plate-scale calibration
Tell us your plate size once. Every scan uses it as a real-world ruler, so portions are sized to your table instead of guessed.
One-tap water tracking
A daily goal worked out from your body weight. Tap a glass, bottle or large bottle — in ml or oz — and undo in one tap.
Eating plans that fit you
Heart-Healthy (DASH), Diabetes-Friendly, Low Fat, Keto, Mediterranean, vegan and more — each with its own macro and fiber targets.
Intermittent fasting timer
Pick 16:8, 18:6 or 14:10 and your first-meal time. A live timer shows how long until your eating window opens or closes.
Real photo analysis
GPT-4o vision identifies each dish, estimates portion, and returns structured nutrition — not a food-database lookup.
Everything is editable
Change quantity, unit, cooking method, or delete an item entirely. Totals recalculate in real time.
Weekly & monthly trends
See average calories, protein, on-target days and logging consistency. Progress is direction, not a single day.
AI Nutrition Coach
Pro members get a personal coach that answers using their meal history, macros, and goals — plus a daily insight on the dashboard.
Private by default
Meal photos are yours. No sharing without your explicit action. We don't train AI models on your data.

Answers to the honest questions
How accurate are the calorie estimates?
They're estimates — usually within 10–20% for common dishes with good lighting, less accurate for mixed dishes and unusual portions. That's why every value is editable and every item has a confidence score.
Is this a medical device?
No. CalorieLensAI is not a medical device, does not provide medical advice, and does not guarantee allergen safety. If you have a medical condition or eating-disorder concern, please consult a qualified professional.
Do you train AI on my meals or photos?
No. Your photos are used to produce your nutrition estimate and stored only in your journal. You can delete an image after analysis while keeping the nutrition record. We do not use your data to train models.
Can I cancel any time?
Yes. Monthly and Annual subscriptions can be cancelled from your device's Subscriptions settings (App Store / Google Play) or from the Customer Center inside the app. You keep Pro access until the end of your current billing period.
Which units does the app support?
Both. Choose Metric (kg, cm, g) or US Standard (lb, ft/in, oz) at onboarding — you can switch any time in Profile. Food items support grams, ounces, cups, tablespoons, slices, eggs and more.
Where does the nutrition data come from?
AI-detected foods are matched against nutrition data during analysis. Values are labeled with a per-item confidence score so you can see when to double-check. See our science page for the exact formulas we use to compute your daily targets.
Does it support heart-healthy, diabetes-friendly or fasting plans?
Yes. Choose Heart-Healthy (DASH), Diabetes-Friendly, Low Fat or one of 11 other eating styles and your daily macro and fiber targets adjust to match. Turn on intermittent fasting (16:8, 18:6 or 14:10) for a live eating-window timer, and the AI Coach will suggest meals that fit your plan and window. These are general nutrition tools, not medical treatment — if you manage diabetes or heart disease, follow your care team's advice.
How is my daily water goal set?
We start at about 35 ml per kg of body weight (rounded to the nearest glass) and you can change it any time in Settings → Goals. Log a glass, bottle or large bottle with one tap, in ml or oz.
How does the referral program work?
Every account has a unique referral code (visible under Profile → Invite friends). Anyone who signs up with your code gets 4 bonus AI scans on day one — 8 total before hitting the paywall. Once they pay their first month of Pro, we credit your Stripe balance with 1 free month (auto-applied to your next invoice). Stackable up to 12 free months per year. Fraud gates prevent self-referrals and duplicate rewards.
