SajuSlim is an AI-powered diet and nutrition tracker. Photograph a meal, search it by name, or log it with one tap — and see calories and macronutrients immediately. THREE WAYS TO LOG A MEAL · AI photo analysis — snap your plate and get an estimate of calories, protein, carbohydrates and fat · Search by food name · One-tap presets tailored to you Nutrient values come from the food composition database published by the Korean Ministry of Food and Drug Safety (MFDS). Sources are listed in the app under "Information sources." SEE WHERE YOUR DAY STANDS · A daily calorie ring against your target · Protein, carbohydrate and fat for every meal you log · Weekly and monthly intake statistics · A meal timeline you can scroll back through REACH A WEIGHT GOAL Set your current weight and a target, then track progress alongside your daily intake. A short daily check-in keeps the trend line honest, and you can skip a day without breaking anything. NO ACCOUNT NEEDED TO TRY IT Guest mode gives you the full logging experience. Sign in only when you want your records saved across devices. PERSONALIZED BY YOUR BIRTH CHART SajuSlim also reads your saju — the traditional Korean four pillars of destiny, based on your birth date — to work out which of the five elements (wood, fire, earth, metal, water) runs high or low for you. That reading shapes which foods and nutrients the app suggests, and gives each logged meal a match score. If you are curious about the tradition itself, a daily saju reading is included as well. You do not need to believe in any of it for the tracker to work. Calorie and nutrient logging runs the same either way. A NOTE ON WHAT THIS IS NOT SajuSlim provides lifestyle and nutrition information for reference and education. It is not a medical device and does not diagnose, treat or prevent any condition. Nutrient estimates from photographs are approximations. If you have a health condition, are pregnant, or take medication, please talk to a qualified professional before changing your diet.
