Most calorie apps hand you a goal from a formula and never check if it works. MacroStack checks every week. It compares what you logged against how your weight actually moved, reveals what your body really burns, and retunes your goal. THE ADAPTIVE ENGINE A textbook formula can only guess your metabolism, and your metabolism changes as you diet. A static goal quietly stops working. MacroStack treats your own results as the source of truth: - Revealed TDEE: the calories your body actually burns, computed from your logs and weigh-ins - Weekly recalibration that adjusts your goal and explains every change in plain language - A weight trend that smooths daily scale noise into a line you can trust - A forecast of where you are heading once enough data lands - Steady when the data says steady. No random goal churn. Cutting, bulking, or maintaining, it works the same way: your results drive your targets. TRACK FAST - 395,000+ foods, searchable offline - Barcode scanner - Popular restaurant items built in - Custom foods and recipes - Today at a glance: progress ring, remaining calories, and a bar for every macro - Home screen widgets and streaks AI FOOD SCANNER No label and no barcode? Point the camera at your plate and get calorie and macro estimates in seconds. AI NUTRITION COACH Ask what to eat. The coach answers with your numbers in front of it: remaining calories, protein gap, current goal. Meal ideas, weekly meal plans, and progress summaries grounded in your actual data. FASTING, IF YOU WANT IT An optional fasting timer with eating window reminders. PRIVATE BY DESIGN No account, no signup. Your log lives on your device and works offline. Export anytime, with encrypted backups when you want them. Set a goal, log your food, step on the scale. The engine does the rest.
