Sunblock app for iPhone and iPad

Take care of your skin, protect it from the sun.

Sunblock helps you take the guesswork out of protection yourself and your children from the dangerous UV radiation that grows every year.

It shows the DAILY UV Index which is an average around solar high of a day - not the UV Value at current Time (which is useless since it is the daily dosage that is interesting)

No longer do you need to guess if you have the right amount of SPF in your sunlotion for the activities your are planning. Simply open Sunblock, read the current UV-index - adjusted for your environment - and you will immediately see if your chosen SPF is enough for the day.

Easily plan your trips outside in the sun with the weekly UV calendar.

Sunblock automatically determines your position and altitude via the Global Positioning System, it then downloads satellite data for your specific location and tells you what the current UV index is.

However: UV rays are reflected from many surfaces and it will be enhanced by the terrain or environment in which you find yourself. Even the protection from our atmosphere degrades the higher you get.
- Therefore Sunblock will automatically adjust for your current altitude
- It will offer you the option to enable Environment modifiers (such as Snow / Beach / Ocean)
- and this enables Sunblock to give you a much more precise uv-index.

USAGE INSTRUCTIONS:

Upon loading Sunblock the first time, be sure to select the correct Skintype in Settings. Select the skintype that fit your skincolor and type best.

TIPS:
A few tips that will make your experience better:
1: It is important to note that reapplication of the same sun screen does not increase the SPF value, or the safe sun exposure time. Reapplying SPF15 throughout the day will not extend the safe sun exposure time beyond 15 times the applicable UV Index for a particular Skin Type.
2: UV exposure varies mainly with the height of the Sun in the sky. This is highest during the summer months, particularly during the 4-hour period around noon at which time the Suns rays travel the shortest distance to Earth. A good rule of thumb is that if the length of your shadow is shorter than your height, then sunscreen is required. Protection at midday is essential, and strong sunscreen with a high healthy SPF throughout the day is always a good idea for maintaining healthy skin and avoiding skin cancer.

Tan safely on your vacation / holiday / ski trip / home / mountain / hike / walk and remember to avoid sunblock with phthalates and parabens and other dangerous additives.
