Methylation Coach AI is a personal mobile companion that leverages the records of what you eat each day with the genetic variants that shape how your body processes key nutrients, turning two dense data streams into one clear, daily recommendation.

Nutrition data is drawn from Cronometer API export that logs in and retrieves recent entries, while raw genetic reports are parsed for the SNPs that matter most in the methylation pathway. These are then processed via an AI provider of your choise so that a single actionable insight can be generated: one sentence of guidance, a practical next step and the brief reasoning that links today’s nutrients to your genetics. Credentials and genetics stay on-device; only the minimum necessary data leaves the phone, and a local history keeps past insights available for reflection over time. There is also a chat mode where you can ask further questions or request accomodations to your dietary needs.

The work grew from the recognition that methylation is heavily influenced by both diet and common genetic variants, yet reading the two together is rarely straightforward without specialist help. By automating the analysis and keeping sensitive information local, the app aims to lower that barrier, offering a calm daily moment of clarity rather than another layer of complexity. The app was submitted to the Apple Store as a proof of concept to evaluate market fit.
