Twitter co-founder Jack Dorsey is involved in the app building up fuss. After releasing a Bluetooth-based messaging app called Bitchat earlier this month, Dorsey this week revealed another app called Sun Day that helps users track UV exposure and vitamin D intake.
The new app is available via TestFlight on iOS, and the code is available on GitHub for anyone to clone.
Like other developers, Dorsey is on the bandwagon of code for atmosphere. But instead of using cursors, claud codes or windsurfs, he says he uses an open source coding tool called Goose.
Sunday is easy to use. You will see the UV index of your location, along with details such as cloud cover, sunrise, and sunset timing. You can choose your skin type based on six options and what kind of clothing you are wearing. Based on these parameters, the app calculates how long your skin can be exposed to sunlight before it starts to burn.

The app also shows minimal vitamin D intake. Start a session and tap the UV Exposure button. After the session is over, the app will show you how much vitamin D you have acquired during the session and on the day.
