The app works using a specifically developed timer to inform the user of their exposure behaviour and is available to download to a smartphone for free.
Intuitive, easy-to-use and educational, the application is related to an extremely precise algorithm that dynamically accounts for various factors: location, the way the user tans, the moment of the day and the real SPF level of the sun protection applied.
The algorithm is based on an intensity curve determined every minute (at the user’s location) and the real protection of the sun cream being used, and that allows determining exposure by the minute.
Other approaches available time the user’s exposure based on maximum sun intensity (based on the maximum number of hours individuals should be in the sun before reapplication); however Lancaster says that its application is different as it takes dynamic sun intensity into consideration to calculate individual’s exposure levels.
How it works
When the user is ready to start their tanning session, they can just click on the button and the countdown timer starts.
An alarm and pop-up message will then alert them to the nearest minute when they should re-apply sun protection.
When the optimal sun exposure time limit has been reached, the app will also advise the user to stop sun exposure to reduce the risk of burning, allowing consumers to enjoy sun bathing while being protected with the appropriate protection.
Lancaster says that even the most advanced sun lotions need to be regularly re-applied, so now the Sun Timer App can help educate and advise consumers concerning sun exposure.
The app is designed to be used almost anywhere in the world, and is available to download from both IOS and Android devices or to scan with a smartphone QR reader from mid-April 2016.
