Logify - Food Journal

Logify is the calorie counter that doesn't feel like bookkeeping. Say, type or photograph what you ate – Logify estimates calories and macros and logs it for you.

Important: the AI features (photo, voice, text) only work with your own API key from Anthropic, Google or OpenAI. Everything else works without AI.

LOG FOOD IN SECONDS • Photo: take a picture of your meal and AI recognizes what's on the plate* • Voice: just say what you ate* • Text: “a slice of apple pie with whipped cream” is enough* • Follow up in the chat: “the slice was smaller” – the estimate is adjusted* • Barcode scanner for packaged products • Food search with favorites, recent and frequent foods • Save your own meals and log them again with one tap * AI feature, requires your own API key

YOUR DAY AT A GLANCE • Calorie budget with rings for protein, carbs and fat • Burned calories, steps and workouts from Apple Health • Log water with a single tap • Breakfast, lunch, dinner and snacks clearly separated

INTERMITTENT FASTING • Timer for 16:8, 18:6, 20:4, OMAD or your own schedule • Fasting phases from digestion to autophagy • History and statistics of your fasts

STATISTICS THAT MOTIVATE • Streaks with golden fruits for every milestone

KEEP AN EYE ON TOLERANCE • Rate meals and note symptoms • Logify shows which foods coincide with symptoms unusually often

YOUR DATA IS YOURS • No user account, no servers of our own • Sync through your private iCloud • The BLS and USDA food databases are built into the app – searching them never leaves your device

ALSO INCLUDED • Widgets for calories and water • Apple Watch app • Reminders for meals, water and fasting • Light and dark mode • Metric and US units

AI ONLY WITH YOUR OWN API KEY Logify's AI features – logging by photo, voice and text, and the chat – only work once you add your own API key from Anthropic, Google or OpenAI in the settings. You get the key directly from the provider, who bills you for usage. Your requests go straight to the provider you choose. Without a key, the barcode scanner, food search, fasting, water, weight and statistics remain fully available.

Logify is not a substitute for medical advice. The intolerance hints are patterns from your own entries, not a diagnosis.
