Logging a meal takes one photo. Point your phone at the plate. Calories, protein, carbs and fat land in your diary in seconds — no searching a food database, no weighing, no typing a portion size. That is the whole thing. HOW SLIMMING WORKS 1) Answer a few quick questions to get your daily calorie and macro targets 2) Snap a photo of your meal 3) It is logged — calories and macros, broken down item by item FREE SCANS EVERY DAY Scanning is not locked behind a subscription. You get free scans every single day, and you can watch a short ad to unlock another one. No trial that quietly expires into a paywall. FASTER THAN TYPING IT IN Missed an ingredient, or was the portion bigger than it looked? Say so in a few words — "the chicken was grilled, not fried" — and it redoes the numbers. Still quicker than entering the meal yourself. EXACT NUMBERS FROM BARCODES Scan a packaged food's barcode and read nutrition straight off the label. CHECK BEFORE YOU EAT Turn on the allergens and diets that matter to you — 14 major allergens plus medical and lifestyle diets like keto, halal, kosher and low-sodium. A barcode scan checks the label against what you've set and flags a match. This is a heads-up from public food data, always worth verifying yourself, never a guarantee. WORKOUTS COUNT TOO Log a walk, a run, or a session with weights, and those calories come back into your day. STAY CONSISTENT Streaks, badges, and a weekly recap worth sharing. Simple charts show goal progress, weight and BMI. SLIMMING PREMIUM • Unlimited scans, every day • Trends and history — 7, 30 and 90 days • Never watch an ad to keep scanning $7.99/month or $39.99/year, with a 7-day free trial. Cancel anytime — the button is where you expect it. NOTE: We do not offer medical advice. Calorie and macro figures are estimates for general wellness.

Verdict
The clearest difference is ratings volume: CTrackAI at 22 against Slimming's 1. On price, rating, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. CTrackAI sells 2 in-app purchases, starting at $9.99 per month and Slimming sells 2 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.9 for CTrackAI against 5.0 for Slimming. That said, the two scores are not equally well evidenced: CTrackAI has 22 ratings behind it against 1, so its average is the more settled of the two.
CTrackAI ships an update weekly, Slimming every 10 days. Both last shipped on October 31, 2026.
