Sun Day lets users log skin type, clothing, and sun time to calculate safe sun exposure.
The app estimates vitamin D production based on local UV index and user input.
Developed using AI coding tool Goose, the app’s code is available publicly on GitHub.
Twitter co-founder Jack Dorsey has introduced yet another application that can track sun exposure and estimate the vitamin D levels in the human body. Dubbed Sun Day, the app aims to better understand the user’s health. The Sun Day app is currently under testing and is available for iOS via TestFlight.
SurveyThe app uses location-based data which helps in displaying the exact local UV index and sunlight duration. All the user needs to do is input their skin type and clothing coverage, and manually toggle their sun exposure throughout the day. After processing all this data, the application will make an estimate of how much Vitamin D the user may have generated and how long they can stay in direct sunlight without burning.
This is an open-source project with the code published on GitHub. As per the reports, Dorsey and his team made the application Goose, which is an AI-based coding tool. He described the project as part of his learning process, experimenting with solo development using open-source AI tools.

This comes amid the growing interest in AI-assisted development tools. Many tech giants including Meta, OpenAI, and Google have been hiring and forming AI teams as a part of their long-term strategy.
Meanwhile, Jack Dorsey also introduced a new application called Bitchat, a decentralised, peer-to-peer messaging app that works without the internet using Bluetooth Low Energy mesh networking. Currently in beta via TestFlight, it requires no registration or servers, supports encrypted chats, and is designed for anonymous, offline communication in remote or emergency situations.
However, the details about the official details about the public are under wraps and it has a current test limit of 10,000 users. The app may also expand support for more platforms, claims a report.
