iPhone
Know when to put sunscreen on and when you have had enough sun. Real UV data, honest limits, no scare tactics.
Helia is the honest solar coach. Most sun apps either push you to maximize a tan or just show a raw UV number. Helia does neither. It treats sunlight like what it is — something to enjoy on a budget. The sunburn is the enemy, not the sun.
Helia reads today's UV conditions for your exact location and your skin, then gives you one clear answer: roughly how long you can be in the sun before you should cover up, reapply, or head for shade. That answer — your sunburn budget — is free, forever. We never put safety behind a paywall.
THE FREE SAFETY CORE — for everyone
• Hands-free tracking. Helia can notice when you head out into daylight, meter the session itself, and log it — no timers to start or stop.
• Your sunburn budget. A personalized estimate of how long today's sun may take before your skin has had enough, based on the live UV index and your skin type.
• The Answer. One glance tells you whether it's a cover-up day, a quick-session day, or a stay-out day — no decoding color charts.
• Live UV index + forecast. See the UV climb and fall through the day so you can plan around the harshest hours.
• Cloud- and rain-aware. Helia corrects the UV for the real sky, so an overcast day reads honestly — not as full sun.
• Reapply & cover-up nudges. Gentle reminders to top up sunscreen or step into shade before you've used up your budget.
• Honest by design. Helia rounds toward caution. When in doubt, it tells you to protect.
PRO — the coaching layer (optional)
Pro turns Helia from an instrument into a coach, with guidance grounded in how sunlight affects the body across the day:
• Morning-light timing. Helia suggests when a little outdoor light may help support your daily rhythm and energy — the circadian side of sunlight.
• Your vitamin-D plan. A 12-month, season-aware calendar of what sunlight can realistically contribute at your latitude — including the honest winter months when it can't. The live estimate on Home stays free.
• The Sun Atlas. Every session and every walked Sun Trail on one map — your sun, over time.
• On-device science coach. Ask anything about sun, UV, vitamin D, and your body clock — answered privately on your phone, grounded in cited sources, never the cloud.
• History & trends. Your sun, your budget used, and your patterns over weeks and seasons.
WHY PEOPLE KEEP HELIA INSTALLED
Helia isn't trying to get you a deeper tan or sell you fear. It's a quiet, trustworthy instrument that earns its home-screen spot.
PRIVATE BY DESIGN
Helia works for you, not on you. Your sun sessions, skin type, and location stay on your device wherever possible and are used to personalize your estimates — not to profile you. Precise location is used only to read your local sun and UV conditions. The coach runs entirely on your device.
A NOTE ON HEALTH
Helia provides general wellness estimates and guidance, not medical advice. Sunburn-budget and vitamin-D figures are estimates based on public UV data and the details you provide — they may differ from reality. Helia does not diagnose, treat, or prevent any condition. For anything concerning your skin or health, please consult a qualified clinician.
