## What is Helia?

Helia makes the invisible chemistry of sunlight visible. It estimates the vitamin D you make from the sun and take from supplements and food, fills a daily target like a budget, and tells you the smartest, safest way to top it up.

YOUR DAY, IN ONE NUMBER
• Today's vitamin D vs. your target, split by sun and supplements
• A live sky background that follows the time of day and real weather
• An hourly UV curve and a sun-path arc

GET SUN SAFELY
• A live sun-session timer with a real-time IU ticker and a sunburn (MED) gauge
• Haptic milestones and a warning before you burn
• The best window to get sun today — or when to just take a supplement instead
• A Live Activity and Dynamic Island that track the session while you're outside

CONNECTED
• Reads time-in-daylight and outdoor workouts from Apple Health; writes your doses back
• Home Screen and Lock Screen widgets for vitamin D, UV index and time in daylight
• An Apple Watch app with three complications
• Siri and Shortcuts: log a dose, start a sun session, or ask where you stand
• Optional iCloud sync across your devices

HELIA PRO
• Month and quarter history
• Your modelled blood 25-OH-D level, calibrated to lab results you enter
• Watch auto-tracking
• Custom alerts and Share Studio — turn your sunlight into a card or a video

PRIVATE BY DESIGN
Your records stay on device with optional iCloud sync; Health data is read live and never uploaded; location is coarse and never stored precisely. No ads, no trackers. Free to use, with an optional Pro upgrade.

Helia provides estimates, not medical advice, and is not a medical device. Consult a qualified clinician.
