Lunar Fasting

Fasting, water, weight and calories — tracked against the real lunar calendar. Snap a photo of your meal and get a calorie estimate, with Apple Intelligence keeping the photo on your iPhone. INTERMITTENT FASTING Log your meals and the app works out your fasting windows automatically — no timer to start or stop. Choose a protocol from 12:12 to OMAD; past days are always judged by the protocol that was active at the time, so changing your goal never rewrites your history. CALORIES FROM A PHOTO (Pro) Take a photo of your meal and the app breaks it into dishes and estimates calories for each portion. You choose who does the counting: • Local — Apple Intelligence on your device (iPhone 15 Pro or later, iOS 27): the photo never leaves your phone, no key or internet needed. • Cloud — OpenAI, Qwen, Gemini or DeepSeek using your own API key. In Auto mode the app tries Apple Intelligence first and falls back to your key. You can also type calories in by hand — that's free. MY FOODS Every food you log is saved to your library: favorites, recent items, servings (×2, ×3) and one-tap repeat of a previous meal. WATER Log water in one tap — it goes straight to Apple Health. Your daily goal is calculated from your weight (33 ml/kg) or set manually. WEIGHT Weight history with a chart and a reminder to weigh in regularly. WIDGETS Small, medium and large widgets: today's lunar day, fasting timer, water, calories eaten and burned, plus quick buttons to add water, log a meal, add a saved food or snap a photo. GOOGLE HEALTH → APPLE HEALTH Wear a Google-connected band? Sign in with Google and the app copies workouts, heart rate, steps, energy, distance and sleep into Apple Health, without duplicates. Optional, off by default. REAL LUNAR DAYS Not the generic calendar month: actual lunar days from moonrise to moonrise at your location, with moon phases. ACTIVITY INDEX AND FORECAST (Pro) Each day gets one activity score (0-100) from your steps, active energy, workouts and stand hours. See trends by lunar day and moon phase, and a forecast for the whole lunar month ahead. DAY RATINGS AND STATISTICS Rate each day on your own criteria — mood, energy, sleep, productivity — and see charts for activity, steps, water, weight, calories and ratings over a cycle, 3/6/12 months or your full history. SMART SCHEDULE Optional reminders for water and your eating window, built from your wake/sleep time and fasting protocol, with quick-log buttons right in the notification. PRO (SUBSCRIPTION) Photo calories, the full lunar-month forecast and the activity index are part of Pro, which includes a 3-day free trial. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel it anytime in your Apple ID settings. PRIVATE BY DESIGN No account and no server of ours. Your data lives on your device and in your Apple Health. We collect only anonymous usage statistics (which features are used) — never your meals, weight, photos or health data. If you add your own OpenAI, Qwen, Gemini or DeepSeek key, a photo goes straight to that provider; the developer never receives or stores it.
