The provided research suggests that using a photo-based meal diary combined with CGM data may help people with diabetes improve glycemic metrics such as time in range. The evidence is early and limited, with pilot/retrospective study designs and product-linked research, so it supports potential usefulness rather than definitive clinical benefit. It does not establish treatment effects beyond self-management support.

Undermyfork is a diabetes management app designed to help users track how specific meals affect their glucose levels. By integrating with continuous glucose monitors (CGM), flash glucose monitors (FGM), or blood glucose meters (BGM), the app automatically combines glucose data with meal photos to calculate the postprandial Time in Range for each meal. This feature allows users to identify which meals help maintain optimal glucose levels and which do not.

The app simplifies meal tracking by allowing users to take photos of their meals, which it then analyzes to suggest tags and automatically syncs with glucose and insulin data. This process helps users easily compare their glycemic responses to similar meals and situations, providing insights into their dietary choices.

Undermyfork also offers a feature called "Insights," which highlights meals that keep glucose levels within the target range and those that do not. This visual feedback helps users make informed decisions about their diet and insulin dosing. Additionally, the app supports data sharing with healthcare providers, enabling users to print their data or create a sharing link for real-time monitoring through Undermyfork Care. This feature enhances collaboration between patients and healthcare providers, facilitating better diabetes management.
