Sunshine: Vitamin D & Daylight for iOS: Limited-Time App Store Discount

Sunshine: Vitamin D & Daylight for iOS is currently available at a limited-time discount, dropping from $9.99 to $6.99—a 30% savings of $3.00. This unique productivity app addresses a common health blind spot: sunlight exposure. While most people track steps, sleep, or calories, few monitor how much natural light they actually get. Sunshine fills that gap by automatically tracking daylight using the Apple Watch’s ambient light sensor (Series 6 or later). It estimates vitamin D production based on UV index and skin type, offers a safe sun timer to prevent burns, and sets daily goals to build healthy habits. The app is best for anyone struggling with fatigue, low vitamin D, poor sleep, or simply wanting to establish a consistent outdoor routine. Compared to other health trackers, Sunshine stands out for its automatic, passive logging—no manual input required. The discount makes it a solid value for those who already own an Apple Watch and want to optimize their wellbeing. If you’ve ever wondered whether you’re getting enough sunlight, this app provides the data you need, and at $6.99, it’s a worthwhile investment in your daily health.
