Logify: AI Calorie Counter

Logify is the calorie counter that also keeps track of how your food agrees with you. Say, type, or snap a photo of what you’ve eaten — Logify estimates calories and macros, logs everything for you, and over time shows you which meals you tend to feel worse after. One-time purchase. No subscription, no account.

AI AT NO EXTRA COST: APPLE INTELLIGENCE
On devices with Apple Intelligence, you can log meals with AI right from the first launch – no sign-up, no API key, no extra cost. Or connect Logify to your own API key from Anthropic, Google, or OpenAI. That works on devices without Apple Intelligence, too.

LOG FOOD IN SECONDS
• Photo: snap your meal and the AI recognizes what's on your plate*
• Voice: just say what you ate*
• Text: "A slice of apple pie with whipped cream" is all it takes*
• Follow up in the chat: "The slice was smaller" – the estimate updates*
• Barcode scanner for packaged foods
• Food search with favorites, recent, and frequently eaten items
• Save your own meals and log them again with one tap
* AI feature: requires Apple Intelligence or your own API key

TRACK HOW FOOD AGREES WITH YOU
• Log symptoms like bloating, stomach pain, or heartburn alongside your meals
• Rate how well you tolerated each meal: good, okay, or poor
• See which foods often show up around your symptoms

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

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

STATS THAT MOTIVATE
• Weight trend with goal weight and forecast
• Food energy, energy expenditure, and water by month and year
• Days on target, calorie balance, and detailed macros
• Streaks with golden fruits for every milestone

YOUR DATA BELONGS TO YOU
• No user account, no servers of our own
• Sync via 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

HOW THE AI WORKS
Logify uses Apple Intelligence automatically as soon as it's turned on in iOS Settings. Alternatively, add your own API key from Anthropic, Google, or OpenAI in Logify's settings. You get the key directly from the provider, they bill you for usage, and your requests go straight to them. Without AI, the barcode scanner, food search, symptom tracking, fasting, water, weight, and stats remain fully available.

Logify does not replace medical advice. The food intolerance insights are patterns from your own entries, not a diagnosis.
