ArcFast vs DeepFast

ArcFast is a simple fasting tracker built around a free, no-ads intermittent fasting timer. Start a fast in one tap, follow your fasting window, use reminders and widgets, and review your history without clutter. KNOW YOUR BODY ArcFast displays your current metabolic phase in real-time as you fast: Sugar Burning transitions into Fat Burning, then Ketosis and Deep Ketosis. Stay informed about what's happening inside your body during every fasting window. SEE YOUR PROGRESS Fasting streaks, weekly bar charts, and detailed session history help you spot patterns and celebrate consistency. Review any missed fasts and learn from your patterns over time. BEAUTIFUL THEMES Four carefully crafted themes — Cosmos, Midnight, Cloud, and Linen — let you personalize ArcFast to match your style. Your fasting experience should feel as good as it looks. FLEXIBLE FASTING PLANS Choose from popular presets including 16:8, 18:6, 20:4, 22:2, and OMAD — or create a custom fasting schedule that fits your lifestyle. STAY ON TRACK Daily reminders to start and end your fasts, milestone notifications, and streak nudges keep you accountable without the noise. WIDGETS Add ArcFast widgets to your Home Screen for quick at-a-glance fasting status without opening the app. FOOD SCAN Add quick calorie estimates to your fasting routine. Take a photo of your meal and ArcFast gives you a clear estimate of calories and food items, so you can understand what you eat between fasting windows. Estimates are for guidance only and are not medical or nutritional advice. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
