Everything You Need to Know About BMI, Calorie & AI
Answers to top questions regarding AI health tracking, BMI accuracy, water intake calculation, and calorie photo recognition.
What makes BMI, Calorie & AI different from basic BMI calculators?▾
Most BMI calculators only divide weight by height. BMI, Calorie & AI by Appgah is an all-in-one health companion that combines WHO BMI tracking with an AI Calorie Scanner for meals, a Daily Water Tracker with 7-day habit streaks, the US Navy Body Fat formula, and a voice-powered AI health coach that answers diet and workout questions in real time.
How accurate is the AI Calorie Scanner from meal photos?▾
The AI food recognition engine identifies ingredients on your plate and allows portion adjustment in grams. By fine-tuning portion sizes, you get accurate per-item macronutrient breakdowns (protein, carbohydrates, fats) and calorie totals in 15+ languages.
How much water should I drink daily according to the app?▾
The app calculates your baseline water intake target based on body weight (35ml per kg of weight) and adds smart increments for physical activity (350ml to 1100ml) and warm climates. You can log water with 250ml, 500ml, and 750ml presets to build a 7-day streak.
Why does the app include the US Navy Body Fat formula alongside BMI?▾
BMI does not distinguish between lean muscle tissue and body fat. Athletes with high muscle mass can register as 'overweight' on BMI charts despite having very low body fat. The US Navy formula uses neck, waist, and hip circumferences to analyze true body composition.
Can I export health reports for my doctor or trainer?▾
Yes! The BMI, Calorie & AI app includes one-tap export of professional medical PDF summaries and historical CSV spreadsheets, perfect for sharing with your physician or fitness trainer.
Does the app work offline?▾
Yes! All calculations, history tracking, and water logs work completely offline using local device storage. You can also sync securely across devices using Google or Email login.
