Logging

Five ways to log a meal.

Pick whatever's quickest right now: describe your meal in the chat, say it out loud, snap your plate, scan the barcode or search the database. The AI asks back when something is unclear – like the portion size.

  • Chat with text, voice or photo – the AI estimates calories and macros
  • AI without a key via Apple Intelligence (iOS 27 and later), or with your own API key (Gemini, Claude, ChatGPT)
  • Barcode scanner and search in BLS, USDA and Open Food Facts – always works, even without AI
  • Favourites, recently eaten and saved meals with a photo
  • Portion in grams or pieces, time and meal of your choice

Food tolerance

Find out what doesn't agree with you.

Rate every meal with a face and log symptoms. Logify links them to the meals of the last 24 hours and shows you in the statistics which dishes stand out.

  • Rating per meal: good, so-so or bad
  • Nine symptoms: bloating, stomach ache, heartburn, diarrhea, nausea, feeling of fullness, headache, fatigue, skin
  • Free-text note and time for every symptom
  • "Possible Intolerances": how often, which symptom, what percentage
  • Not a medical device – Logify shows patterns, not diagnoses

Statistics

Your month, your year.

Statistics sum up what matters: how much you ate and burned, how your weight develops, how well you hit your macros and how much you drink.

  • Monthly or yearly view
  • Food energy, energy expenditure and balance
  • Average macros against your goal
  • Weight trend with forecast
  • Calendar with all your days at a glance

Apple Health

Activity and weight included.

With your permission, Logify reads workouts, steps and active calories from Apple Health. Your calorie goal is based on what you actually burned over the last 30 days – move more than usual, and your daily budget grows by the difference. Weight, height and age fill in your profile.

  • Moving more than usual raises your daily budget
  • Weight from Apple Health or entered by hand
  • Calories, water and weight written back to Apple Health
