It’s great that the iPhone 4 and the iPhone 4S are equipped with an LED light, that may not only be used to take pictures. The app “LED Machines” is very resourceful when it comes to using the light source in various other ways.
As soon as the app is being started, a large button will be visible. It permanently turns the LED light on, transforming it into a mobile flashlight. A feature that one might easily get used to, since it could come in handy in a dark garden shed or during a nightly visit to the bathroom. A small button activates a blinking light.
With a swipe of the finger the user goes from one function to the next. A virtual typewriter accepts short texts that are being converted by a Morse Coder, utilizing the blinking LED light. A handsome analog clock with alarm plus a weather report complete the app.
