Jack Dorsey, former CEO of Twitter and co-founder of Block (formerly Square), has launched a unique wellness-focused app that helps users monitor their daily sun exposure. The app, called Sun, is designed to promote healthier lifestyles by providing real-time insights into how much sunlight a user receives each day, both indoors and outdoors.
The app combines weather data, real-time UV index tracking, and device-based location monitoring to determine how much time you’re spending in the sun. While fitness and wellness apps have often focused on movement and sleep, Sun aims to address a frequently overlooked factor in personal health: natural light. Dorsey’s vision appears to go beyond aesthetics; he wants to encourage people to develop healthier habits around their relationship with light.
Currently, the app is in early access and has a minimal, elegant design. It offers a simple dashboard that displays how long you’ve been outside, when UV exposure is optimal, and even when to avoid it due to intensity. The app also allows users to set sunlight goals, ideal for those looking to balance their circadian rhythms or boost vitamin D levels.
The idea seems to stem from a mix of personal wellness philosophy and data-driven tracking. Dorsey has long been associated with health-conscious habits such as cold plunges, meditation, fasting, and now, sun management. This app aligns with his minimalist, biohacker-style approach to health.
