SlimAI Calorie Tracker Features
Track meals, calories, macros, workouts, water, and progress — estimate your body fat from two photos — and get your week read back to you as one insight and one action.
SlimAI Calorie Tracker helps you log food faster, understand your calorie balance, adjust serving sizes, and build a more consistent food and fitness routine on iOS and Android. SlimAI is also the first AI calorie tracker with a built-in AI body fat calculator: AI Body Assessment estimates your body fat percentage from two photos, so you can see progress the scale can’t show.
A tracker that only adds numbers up leaves the interpretation to you. SlimAI closes that gap: AI Coach reads the week you already logged and answers where your weight is heading, what drove it, and the single next thing worth doing — with a written report every Monday and one observed pattern a week drawn from comparing your own fasting, training, hydration, meal timing, and body scan data.
A plan that never changes is the other half of that gap. In SlimAI every fact behind your target stays editable, and changing one — your weight, your goal, your pace, your activity level, your cuisine — recomputes your calorie target, your macro grams, your per-meal budgets, your diet plan, your stats, and your home-screen widgets in one pass, with the new number shown to you before you save it. Log a weigh-in and the same recalculation runs.
Tracking gets harder when your meals, workouts, water intake, steps, and progress live in different places. The features below show how SlimAI turns daily tracking into a clearer routine instead of a scattered process. SlimAI works in 7 languages — English, French, German, Italian, Spanish, Dutch, and Arabic — so you can track in the language you think in.

All SlimAI Features
AI Coach
NewYour logged week turned into three answers: where your weight is heading, what drove it, and the one thing worth doing next — each ending in a button that opens the right screen.
Unique benefit: You get an interpretation of your week, not just a total.
Learn more →Weekly Report
NewEvery Monday, a written summary of the week: calories against goal, macros, weight change, body fat change if you scanned, two to three insights, and one recommendation.
Unique benefit: You get the weekly review you always meant to sit down and do.
Learn more →Health Patterns
NewOne observed pattern a week from comparing your own days — fasting against non-fasting, training against rest, low water against normal, and lean mass against the scale.
Unique benefit: You find out what works for your body instead of for a population.
Learn more →Smart Food Swaps
NewThe heavy dish you keep repeating, replaced by a specific lighter alternative in the same cuisine — at most 70% of the calories, with the most protein per calorie saved, logged in one tap.
Unique benefit: You get a named dish to eat instead, not the advice to “eat lighter”.
Learn more →Adaptive Plan
NewChange your weight, goal, pace, activity level, or cuisine and SlimAI recomputes your calorie target, macro grams, per-meal budgets, diet plan, coach, stats, and widgets — showing you the new number before you save it.
Unique benefit: Your plan describes the body you have now, not the one you had at signup.
Learn more →Adaptive Calorie Goals
NewWhen your weight has been flat for 14 days and your logging has been solid, SlimAI names the plateau and proposes one small change — a lower target or 2,000 more steps. You approve it, and you can undo it.
Unique benefit: Your plan changes when it stops working, without ever changing itself.
Learn more →Ask About Your Meal
NewOne question about one logged dish, answered from its own ingredients and macros, in your app language. No chat thread — deliberately.
Unique benefit: You get an answer about your actual plate instead of a generic nutrition search.
Learn more →AI Body Assessment
Estimate your body fat percentage from two guided photos — plus fat and lean mass, and where fat is stored across six body regions. See what the scale can’t.
Unique benefit: You track what your body does with your effort, not just your weight.
Learn more →AI Calorie Tracker
Log meals, review calories and macros, and connect food choices with daily progress — with less manual effort.
Unique benefit: You get calorie clarity without managing every detail manually.
Learn more →Fast Setup, Personalized Tracking
One question at a time: your goal and pace, body type, one of five activity levels, preferred diet, favourite cuisine, and any health details you choose to share — turned into a daily calorie goal and protein, fat, and carbohydrate targets.
Unique benefit: You start faster with a setup that fits your routine instead of a generic profile.
Learn more →Personalized and Custom Calorie Goals
SlimAI helps estimate daily calorie needs from your inputs, and you can also create your own calorie goal — plus gram-level protein, fat, and carbohydrate targets for athletes and coached training plans.
Unique benefit: You can follow a guided target or set your own calorie and macro goals without losing control of your plan.
Learn more →Macro Tracker
Protein, carbohydrates, and fat shown in grams and percent across every logged meal, recipe details, the daily dashboard, and weekly Insights — against targets you can set yourself.
Unique benefit: You see the structure behind the calorie number, not just the total.
Learn more →Flexible Ways to Log Meals
Log meals by camera, gallery upload, voice input, text entry, database search, recent foods, saved foods, suggestions, or diet-plan-based logging.
Unique benefit: You can log food faster when you are busy and use manual control when you need more detail.
Learn more →Photo Calorie Tracker (Camera Scan)
Point the camera at your meal and get calories, macros, and an ingredient breakdown in seconds.
Unique benefit: You can log real-life meals without searching a database item by item.
Learn more →Voice Calorie Tracker (Voice to Log)
Say what you ate and SlimAI logs it — hands-free food logging for busy moments.
Unique benefit: You can track meals even when typing is not practical.
Learn more →Barcode Scanner
Scan packaged foods to pull calories and macros fast, then adjust servings to match what you actually ate.
Unique benefit: You can check how packaged foods fit your target before you eat.
Learn more →Food Label Scanner
The scanner’s third mode reads the printed nutrition facts panel itself, so store brands, imported products, and anything whose barcode returns nothing can still be logged from the package.
Unique benefit: A product missing from a database never becomes a missing entry in your day.
Learn more →AI Food Recognition You Can Correct
When a scan reads your plate wrong, pick from similar dishes, type what you were actually looking for, adjust the serving, or edit ingredients one by one — before anything is logged.
Unique benefit: A wrong result costs you ten seconds instead of ending the entry.
Learn more →Smarter Serving Guidance & Ingredient Editing
Review meal details, adjust serving size, and add or delete ingredients when a result needs correction — with real-time suggestions for how much of the plate fits your day (0.25, 0.5, or the full serving) and a warning before you exceed your goal.
Unique benefit: You can make better portion decisions while you are eating, not only after you finish.
Learn more →Calories, Macros, and Food Health Score
Every food opens a full detail screen: calories and what share of your goal they take, protein, carbohydrates and fats in grams and percent, a junk-level health rating, percent-of-daily-value nutrition facts, an ingredient-level breakdown with exact weights you can edit or add to, and cooking time with numbered directions.
Unique benefit: You can see what a calorie number is built from, correct it when it does not match your plate, and even cook the dish from the same screen.
Learn more →Daily Calorie Dashboard
One home screen showing calories eaten, your goal and calories burned together, macro progress against your targets, and a recommended calorie range for breakfast, lunch, dinner, and snack — each with a live status: Over Limit, Not taken, Need to Eat, or Optional.
Unique benefit: You can see how many calories you have left and which meals still have room, instead of guessing at dinner time.
Learn more →Diet Plans, Regional Foods & Meal Suggestions
Explore diet plans and meal ideas based on preferences like vegetarian, Mediterranean, keto, or paleo — plus regional food personalization that fits how you actually eat.
Unique benefit: You can find food options that fit your preferences without planning every meal from scratch.
Learn more →Progress, Streaks & Insights
A Statistics screen with Progress, Weight, and Insights tabs: longest streak, logged days, perfect days, calorie and macro trends by week or month, and your weight and body fat charted over time.
Unique benefit: You can review patterns over time instead of judging progress from one day.
Learn more →Weight Tracking
Set a target weight and a pace, see your BMI score and healthy weight range, and let SlimAI turn that into the daily calorie goal your dashboard runs on.
Unique benefit: The scale connects to a daily number you can act on, not just a chart.
Learn more →Workout Tracking
Log workouts and see the estimated calories burned land in the same daily balance as your meals, alongside steps and back-dated exercise entries.
Unique benefit: Training and eating are measured against one number instead of two apps.
Learn more →Step Tracking & Health Sync
Daily steps with your own step goal, plus steps and workouts synced from Apple Health on iPhone and Health Connect on Android — including an Add Back Calories Burned setting you control.
Unique benefit: Everyday movement counts toward the same balance as your meals.
Learn more →Home Screen & Lock Screen Widgets
NewCalories left as a ring banded by macro, a water glass you can top up in one tap without opening the app, your logging streak with an at-risk warning, and your coach’s next line — plus a fasting countdown on the lock screen and the Dynamic Island.
Unique benefit: The number that matters is on the screen you already unlock a hundred times.
Learn more →Reminders That Protect Your Streak
Meal logging nudges, water reminders, fasting window alerts, and a prompt when the day is running out — sent from SlimAI’s servers, so they still arrive when the app has been closed for days.
Unique benefit: The reason you stopped tracking is never that you forgot.
Learn more →Available in 7 Languages
English, French, German, Italian, Spanish, Dutch, and Arabic — the whole interface, including the spoken guidance during a body scan.
Unique benefit: You track in the language you think in instead of translating as you go.
Learn more →Fasting Tracker
Choose from 6 intermittent fasting plans — from a beginner-friendly 14:10 to weekly 5:2 — set your schedule, and keep fasting connected to meals, calories, and water.
Unique benefit: You can follow a fasting rhythm that fits your experience level, in the same app as your food.
Learn more →Water Tracker
Set a daily hydration goal and log drinks by utensil — Jug, Bottle, Mug, or Glass, each with a custom quantity — with percent-of-goal progress and drink history.
Unique benefit: You can keep hydration on track with one-tap logging inside your daily check-in.
Learn more →Why SlimAI Combines These Tools
SlimAI combines these tools because real tracking does not happen in separate parts. Your meals, portions, calories, macros, workouts, water intake, steps, and progress all affect the same routine.
When you use separate apps, you lose context and spend more time connecting the dots. SlimAI brings the core tracking tools into one experience so you can understand what happened, what changed, and what to do next with less friction.
The goal is simple: help you track with clarity instead of managing scattered tools.

Still Wondering About SlimAI
What features does SlimAI Calorie Tracker include?
SlimAI includes AI-powered meal logging by camera, voice, text, and barcode, personalized and custom calorie goals, macro tracking, food health scores, serving guidance, ingredient editing, diet plans, AI Body Assessment, workout tracking, water intake, fasting, steps, back-date logging, and progress history — plus AI Coach, a weekly report, health patterns, smart food swaps, adaptive calorie goals, single-question AI answers on a logged meal, and home and lock screen widgets. Every target in the app is recalculated whenever your weight, goal, pace, activity level, or profile changes.
What is the newest SlimAI feature?
Home and lock screen widgets are the newest addition — a calorie ring banded by macro, one-tap water logging that works without opening the app, a streak tile with an at-risk warning, a coach tile, and a fasting countdown on the Dynamic Island. Before that came AI Coach, which reads the week you already logged and answers where your weight is heading, what drove it, and the one thing worth doing next, with a written report every Monday, one observed cross-feature pattern a week, one-tap food swaps, and plateau detection with an adaptive calorie target. And before that, AI Body Assessment made SlimAI the first AI calorie tracker with a built-in AI body fat calculator.
Does SlimAI have an AI coach or an AI chatbot?
SlimAI has a deterministic AI Coach. It runs fixed rules over your own logged data, so the same week always produces the same sentence, every number traces back to something you logged, and every insight ends in a button that opens the right screen — where a generative chatbot coach would produce a different, unverifiable answer each time you asked. The only AI question surface is Ask About Your Meal — one question about one logged dish, with no conversation thread.
Does SlimAI adapt when my goal, weight, or lifestyle changes?
Yes, and it is the core of how the app works. Editing your goal, target date, weight, height, activity level, body type, cuisine, or health details reruns the same calculation that produced your original plan — and SlimAI shows you the resulting daily calorie target live, before you save. Saving updates your macro grams, your per-meal calorie ranges, your BMI, your diet plan (the cached meals are cleared and refetched against the new budget), your stats and coach, and your home-screen widgets. Logging a weigh-in that is your latest reading triggers the same recalculation, and the confirmation names your new goal. If you set your own macro split, it is kept as a ratio and re-applied to the new total rather than reset.
Does SlimAI tell me what to do next, or only show numbers?
Every coaching surface ends in an action. The coach card gives you one insight and one button that opens the right screen with the context already applied — the diet plan filtered to the meal that overshot, the scanner with the meal type set, the water tracker, or the swap that fixes your protein. The Progress tab shows every achievement including the ones you have not earned yet, with how far the window has come and what is left. The Monday report closes with one thing to try next week, and plateau detection proposes one specific change when progress stalls.
Do I need separate apps for food and fitness tracking?
No. SlimAI connects meals, calories, macros, workouts, water, fasting, steps, and progress in one app, so you can see how food and activity affect the same daily routine.
Which SlimAI features are included in Pro?
SlimAI Pro includes unlimited scans, Speak and Get Your Recipe, Type to Log, priority access to new SlimAI features, and support from a SlimAI representative, $7.99/month or $29.99/year.
Does SlimAI work for different cuisines and regional foods?
Yes. SlimAI supports regional food personalization across cuisines including desi, Asian, American, Mediterranean, and more, so meal suggestions feel closer to how you actually eat.
