From Calories to ActionSlimAI — AI Calorie Tracker with a built-in AI Body Fat Calculator

SlimAI Calorie Tracker is a personalized AI-powered calorie and macro tracking app — and the first AI calorie tracker with a built-in AI body fat calculator. It helps you log meals by photo, voice, or text, track calories and macros, estimate your body fat percentage from two photos with AI Body Assessment, monitor workouts, water, fasting, and steps, and review progress in one connected app.

Yes. AI Body Assessment is SlimAI's built-in body fat calculator. It estimates your body fat percentage from two guided photos using peer-reviewed formulas (US Navy, RFM, CUN-BAE), shows fat mass versus lean mass with regional fat distribution across six body regions, and offers a tape-measure option if you prefer no photos. Results are always an estimate for fitness awareness, not a medical diagnosis, and AI photo analysis is part of SlimAI Pro.

SlimAI supports weight loss by helping you set personalized calorie goals, log meals quickly, understand calorie balance and macros, and stay consistent with daily habits. Individual results vary, and SlimAI does not guarantee weight loss outcomes.

Yes. You can set your own daily calorie target plus gram-level protein, carb, and fat goals — a guided estimate is available, but never forced. When you scan a meal, SlimAI also suggests how much of the plate fits your remaining day (0.25, 0.5, or the full serving) and warns you before you exceed your goal.

Your dashboard shows calories eaten, your goal, and calories burned together, and each meal gets its own recommended range with a live status — Over Limit, Not taken, Need to Eat, or Optional. So you see not just what is left overall, but which meals you still owe and which are optional. The ranges are guidance, not rules.

Yes. AI Coach reads the week you already logged — meals, calories, macros, water, fasting, steps, workouts, weight, and body scans — and answers three things: where your weight is heading, what drove it, and the single next action, with a button that opens the right screen. It is not a chatbot: every sentence comes from fixed rules over your own data, so the same week always produces the same output. The coach card, trajectory, attribution, weekly score, and the Monday weekly report are free.

SlimAI Pro includes unlimited scans, Speak and Get Your Recipe, Type to Log, AI Body Assessment photo analysis, cross-feature health patterns, smart food swaps, adaptive calorie goals, Ask About Your Meal, priority access to new SlimAI features, and support from a SlimAI representative. It is $4.99/month or $34.99/year, with a 3-day free trial.

Yes, and the headline numbers other apps advertise are worth reading carefully. A database count is a count of rows, not of foods: the same item takes a separate row for every brand spelling, plural, language, and portion variant, plus a user-submitted copy from everyone who could not find an existing one — which is why searching a multi-million-row database returns dozens of near-identical entries with different calorie figures. Counted properly, the world’s whole foods run to a few thousand; the millions are branded packaged products and duplicates. SlimAI keeps a 50K+ curated database sized so the right entry is usually the first result, and covers anything missing four other ways — AI photo scan, voice, barcode, and printed nutrition label. A food does not need to exist in a list for you to log it.

Because SlimAI is an app, not a coaching programme, and everything sits in one tier instead of being split across two or three. SlimAI Pro is $4.99/month or $34.99/year — a full year for less than a single month of a coaching programme at publicly listed rates — and it covers unlimited AI scans, body fat estimates, fasting, water, workouts, steps, diet plans, health patterns, food swaps, and adaptive calorie goals. Coaching programmes charge more because a human coach and a written curriculum cost money to deliver. Of the four things a coach does — tell you where you are heading, why, what to do next, and hold you to it — SlimAI’s AI Coach does the first three every week from your own data, and does not claim the fourth.

Yes — that is the point of it. Every fact behind your target stays editable, and changing one reruns the same calculation that produced your original plan. Edit your goal, target date, pace, activity level, body type, cuisine, or health details and SlimAI shows you the new daily calorie target live, before you save. Saving then 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, so a lower target genuinely produces a lighter list — plus your stats, your coach, and your home-screen widgets. Logging a weigh-in that is your latest reading runs 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 instead of being reset.

Every coaching surface in SlimAI ends in an action rather than a number. The coach card reads your logged week and gives you one insight plus a button that opens the right screen with the context already applied — your 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 all three achievements, including the ones you have not earned, with how far you have come and exactly what is left. The Monday report closes with one thing to try next week, and if progress stalls, plateau detection proposes one specific change for you to approve.

SlimAI checks two things before calling it a plateau: whether your smoothed weight trend has been flat for at least 14 days, and whether your logging over that period was solid. If both hold, it proposes one small change — a single step down in calories, or 2,000 more steps a day — and applies neither until you confirm. You can undo it. If your logging was patchy, SlimAI treats it as a data problem and does not touch your calorie target at all.

Yes. SlimAI includes a wide food database covering different cuisines, including desi, Asian, American, Mediterranean, Thai, and more, with regional food personalization so meal ideas feel closer to how you actually eat.

Skipping a day does not ruin your progress. SlimAI supports back-date food and exercise logging, so you can fill in missed entries and get back to your routine without feeling like you have to start over.

Yes. SlimAI respects user privacy and handles data according to its Privacy Policy, which explains how information is collected, used, and protected. You can also review privacy details on the App Store or Google Play listing.

SlimAI supports 7 languages: English, French, German, Italian, Spanish, Dutch, and Arabic. Meal logging and tracking work in all of them.

SlimAI needs an internet connection to work properly. This helps the app access food data, AI features, recipes, and tracking updates accurately.
