Good to know
Questions,
answered clearly.
Sunneuv is designed for everyday wellness context—not diagnosis or medical treatment.
How does Sunneuv personalize my estimates?+
Sunneuv combines live UV and weather with your location, Fitzpatrick skin type, selected SPF, vitamin D goal, and percentage of exposed skin. Results are estimates and may not reflect every personal factor.
Does Sunneuv measure my vitamin D level?+
No. Sunneuv estimates sunlight-related vitamin D synthesis and timing. It does not test blood vitamin D, diagnose deficiency, or replace medical advice.
What can Sunneuv sync with Apple Health?+
Only what you enable. With permission, Sunneuv can read skin type and Time in Daylight, then save tracked Time in Daylight, UV Index, and a vitamin D estimate.
Why does Sunneuv need my location?+
Your location lets Sunneuv provide current UV and weather for where you are. Location access is optional and can be managed in iOS Settings.
How does the 3-day free trial work?+
Eligible new subscribers can try the annual Sunneuv+ plan free for 3 days. It then renews at the displayed App Store price unless canceled. The weekly plan has no trial.
Coming soon
A clearer sunlight routine starts here.
Sunneuv for iPhone is getting ready for launch. Android is planned for a future release.
