What's New in MacroFast
1.2
August 13, 2026
What's new in MacroFast: • Fiber tracking — log fiber alongside calories, protein, carbs, and fat. Barcode scanning populates fiber automatically from Open Food Facts. Fiber syncs to Apple Health with your other nutrition data. • Ask your own AI — export your full nutrition history, fasting windows, and glucose data to your clipboard with one tap, then paste into ChatGPT, Claude, Gemini, or any AI assistant for personalized insights. • Log Again from History — long-press any food entry in the History food log to get the same context menu as Today: Log Again ×1, ×2, or ×3, Edit, or Delete. • Smarter trend charts — weekly and monthly charts now show only completed days in the averages. Today appears as a faded bar so you can see where you're tracking without skewing the numbers. • Photo library fix — the "Choose from Library" button in Add Food now works correctly alongside the camera option. • Calorie precision — values over 1,000 kcal now display two decimal places (e.g. 1.63k) for a more accurate read at a glance.
