Diabetic's Diary

Keep personal health records organized on your iPhone—without creating an account or sending your records to a developer-operated server.

Diabetic's Diary is a private, offline-first record-keeping tool for information you enter yourself. Use it to:

• Log glucose, uric acid, laboratory results, meals, fruit, hydration, medication, and exercise • Review local charts and 7-day, 14-day, or 30-day record summaries • Create medication and hydration reminders using local iPhone notifications • Optionally read activity, workout, and sleep summaries from Apple Health • Optionally save glucose and plain-water entries to Apple Health • Attach meal photos that are automatically removed after no more than 30 days • Export up to 30 days of records as CSV or PDF using the iOS share sheet • On compatible devices, optionally generate a reference-only insight with Apple's on-device system language model
