A developer, frustrated with the existing options for managing diabetes, has meticulously crafted and publicly released a new iOS application called "Islet" designed to streamline and simplify the complexities of diabetes management. Leveraging the advanced capabilities of the GPT-4-Turbo model (a large language model), Islet aims to provide a more personalized and intuitive experience than traditional diabetes management apps. The application focuses on three key areas: logbook entry simplification, intelligent insights, and bolus calculation assistance.
Within the logbook component, users can input their blood glucose levels, carbohydrate intake, and insulin dosages. Islet leverages the power of natural language processing to interpret free-text entries, meaning users can input data in a conversational style, for instance, "ate a sandwich and a banana for lunch," instead of meticulously logging individual ingredients and quantities. This approach reduces the burden of data entry, making it quicker and easier for users to maintain a consistent log.
Furthermore, Islet uses the GPT-4-Turbo model to analyze the logged data and offer personalized insights. These insights may include patterns in blood glucose fluctuations related to meal timing, carbohydrate choices, or insulin dosages. By identifying these trends, Islet can help users better understand their individual responses to different foods and activities, ultimately enabling them to make more informed decisions about their diabetes management.
Finally, Islet provides intelligent assistance with bolus calculations. While not intended to replace consultation with a healthcare professional, this feature can offer suggestions for insulin dosages based on the user's logged data, carbohydrate intake, and current blood glucose levels. This functionality aims to simplify the often complex process of bolus calculation, particularly for those newer to diabetes management or those struggling with consistent dosage adjustments.
The developer emphasizes that Islet is not a medical device and should not be used as a replacement for professional medical advice. It is intended as a supplementary tool to assist individuals in managing their diabetes in conjunction with guidance from their healthcare team. The app is currently available on the Apple App Store.

HN users generally expressed interest in the Islet diabetes management app and its use of GPT-4. Several questioned the reliance on a closed-source LLM for medical advice, raising concerns about transparency, data privacy, and the potential for hallucinations. Some suggested using open-source models or smaller, specialized models for specific tasks like carb counting. Others were curious about the app's prompt engineering and how it handles edge cases. The developer responded to many comments, clarifying the app's current functionality (primarily focused on logging and analysis, not direct medical advice), their commitment to user privacy, and future plans for open-sourcing parts of the project and exploring alternative LLMs. There was also a discussion about regulatory hurdles for AI-powered medical apps and the importance of clinical trials.
The Hacker News post titled "Show HN: The App I Built to Help Manage My Diabetes, Powered by GPT-4-Turbo" at https://news.ycombinator.com/item?id=42168491 sparked a discussion thread with several interesting comments.
Many commenters expressed concern about the reliability and safety of using a Large Language Model (LLM) like GPT-4-Turbo for managing a serious medical condition like diabetes. They questioned the potential for hallucinations or inaccurate advice from the LLM, especially given the potentially life-threatening consequences of mismanagement. Some suggested that relying solely on an LLM for diabetes management without professional medical oversight was risky. The potential for the LLM to misinterpret data or offer advice that contradicts established medical guidelines was a recurring theme.
Several users asked about the specific functionality of the app and how it leverages GPT-4-Turbo. They inquired whether it simply provides information or if it attempts to offer personalized recommendations based on user data. The creator clarified that the app helps analyze blood glucose data, provides insights into trends and patterns, and suggests adjustments to insulin dosages, but emphasizes that it is not a replacement for medical advice. They also mentioned the app's journaling feature and how GPT-4 helps summarize and analyze these entries.
Some commenters were curious about the data privacy implications, particularly given the sensitivity of health information. Questions arose about where the data is stored, how it is used, and whether it is shared with OpenAI. The creator addressed these concerns by explaining the data storage and privacy policies, assuring users that the data is encrypted and not shared with third parties without explicit consent.
A few commenters expressed interest in the app's potential and praised the creator's initiative. They acknowledged the limitations of current diabetes management tools and welcomed the exploration of new approaches. They also offered suggestions for improvement, such as integrating with existing glucose monitoring devices and providing more detailed explanations of the LLM's reasoning.
There was a discussion around the regulatory hurdles and potential liability issues associated with using LLMs in healthcare. Commenters speculated about the FDA's stance on such applications and the challenges in obtaining regulatory approval. The creator acknowledged these complexities and stated that they are navigating the regulatory landscape carefully.
Finally, some users pointed out the importance of transparency and user education regarding the limitations of the app. They emphasized the need to clearly communicate that the app is a supplementary tool and not a replacement for professional medical guidance. They also suggested providing disclaimers and warnings about the potential risks associated with relying on LLM-generated advice.
