There are many people who find the iPhone touchscreen much more accessible with the aid of a stylus. A stylus is a writing utensil or small pen shaped instrument used in many forms of media. For people like me with sweaty fingers a stylus is not just useful, it's a necessity for touchscreen devices.
In the world of technology a stylus is a computer accessory or pointer which is used to select options or perform tasks on a touchscreen device. The iPhone was developed to promote touching the screen with fingers. In order to have a stylus work efficiently with this technology some companies have developed styluses specifically for the Apple iPhone, iPod and iPad touch screens.
These styluses are used mostly during the winter when taking gloves off in order to manipulate the device is most dreaded. The iPhone stylus is probably the best invention for people looking for accurate input into their iPhone device whether they are drawing or using it for simple text or writing. Additionally, they are often used year round by people with hyperhidrosis (overactive sweat glands) that makes it hard to use a touchscreen with their fingers. Also, excessive use of touchscreen devices will eventually cause some form of sensitivity in the finger tips, so for business people who are usually working from their laptop and their iPhones, it is recommended that they get both a USB mouse and an iPhone stylus.
