Blood Sugar Journal
Track glucose, insulin, meals
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Blood Sugar Journal is a simple and thoughtful journal for tracking glucose, insulin, meals, and long-term trends in one place.
It is designed for people who want a clearer picture of daily patterns without turning every entry into a complicated medical workflow. You can log real values, review your day, follow trends, and export your data when needed.
The free version already includes the core diary experience, current charts, PDF export, and local algorithmic insights created directly on your device. Blood Sugar Journal Pro adds AI-written summaries based on your journal data, focused on patterns and data context without treatment advice.
IMPORTANT
Blood Sugar Journal is a journal and pattern-tracking tool. It does not provide medical advice, does not prescribe treatment, and does not replace a doctor or licensed healthcare professional.
