KetoLog is a private food and fasting log for people who count net carbs. Everything stays on your iPhone in an encrypted database. No account, no server, no ads, no tracking. Free. PRIVATE BY DESIGN - Works offline. The app makes no network connections. - Your log is encrypted on the device. You hold the key. - Food photos stay in your photo library. TRACK YOUR DAY - Net carbs against your own goal, with calories, fat and protein. - Saved dishes: log a share or a weight and the app does the numbers. - One-tap repeat for the foods you eat most. FASTING - Start and stop with one tap, with progress toward your target. - A week of eating and fasting hours at a glance. BODY - Weight, ketones, glucose, blood pressure and more, each with its time. - Glucose-ketone index (GKI) from your latest readings. - Water, symptoms and notes. INSIGHTS - Averages, streaks and charts for 7, 30 or 90 days. ON-DEVICE ASSISTANT - On iPhones with Apple Intelligence: write what you ate, paste a food table or send a photo, and ask about your day or week. - Runs on the phone. Nothing you write leaves the device. - Nothing is saved until you approve it. ALSO - Optional Apple Health sync. - Home Screen and Lock Screen widgets. - Encrypted backup file and CSV export. KetoLog is a personal logging tool for adults. It is not a medical device and does not give medical advice. Talk to your doctor before changing your diet or fasting.
