Jack Dorsey Introduces Sun Day App to Track Vitamin D and Safe Sun Exposure

Twitter co-founder Jack Dorsey has launched a new application, Sun Day, which combines health technology with sun exposure tracking. Leveraging real-time UV data, the app estimates Vitamin D synthesis and provides a personalized approach to managing sunlight exposure, aligning with the growing demand for preventive health and digital wellness tools.

Currently in beta on TestFlight for iOS, the app highlights a wider shift toward AI-powered health solutions designed to enhance lifestyle habits, strengthen immunity, and support holistic well-being through more informed choices.

Sun Day leverages location-based services to determine the local UV index and duration of sunlight. After users provide details such as skin type, clothing coverage, and manually log their sun exposure, the app generates estimates for:

The amount of Vitamin D the body may have generated

The safe duration of sun exposure before the risk of sunburn arises

Sun Day’s Relevance and Open-Source Development

This personalized approach is particularly valuable for individuals at risk of Vitamin D deficiencies, including those with limited outdoor activity, darker skin tones, or those living in higher latitudes with weaker sunlight. The app is also part of Jack Dorsey’s broader experimentation with open-source and AI-driven coding tools. The Sun Day project is publicly available on GitHub, inviting developers to contribute or expand upon its code. It was developed alongside Goose, an AI-assisted development tool created by Dorsey’s team. Together, these projects highlight his evolving role as a solo open-source developer exploring the intersection of AI, health, and communication.

Key Features of the Sun Day App

Developed by Jack Dorsey, the Sun Day app delivers personalized, real-time insights into Vitamin D production through the following features:

Vitamin D Estimates – Calculates the amount of Vitamin D the body may have synthesized.

Location-Based UV Data – Utilizes real-time UV index and sunlight duration for accuracy.

User Inputs – Factors in skin type, clothing coverage, and time spent in the sun.

Safe Sun Exposure Guidance – Provides recommendations on how long users can stay outdoors without risking sunburn.

Potential Impact of the Sun Day App on Health

The Sun Day app represents a significant advancement in the health sector by encouraging users to monitor their Vitamin D levels, an essential nutrient for overall well-being. Additionally, it may play a preventive role by helping users avoid the harmful effects of excessive UV exposure, including sunburn, skin damage, and severe conditions such as skin cancer.

Summary:

Twitter co-founder Jack Dorsey has launched Sun Day, a new health app that uses real-time UV data and user inputs such as skin type and clothing coverage to estimate Vitamin D production and provide safe sun exposure guidance. Currently in beta on iOS, the app aligns with the growing trend of AI-powered health tools aimed at preventive care and lifestyle improvement. Available as an open-source project on GitHub, Sun Day not only helps users manage Vitamin D intake and reduce risks like sunburn and skin cancer but also reflects Dorsey’s broader push into AI-driven, open-source health and wellness innovation.
