About this app

This free app provides a collection of rainbow images for you to set them as the wallpaper or background of your mobile phone. This is especially dedicated to rainbow enthusiasts out there.

Rainbow is a natural phenomenon that is adore by many people. Whenever a rainbow appears in the sky, most people will at the very least take a second look at it. Some people might just stop what they are doing for a while to admire its beauty.

Scientifically, this meteorological phenomenon occurs when light is reflected in water droplets causing a spectrum of light appearing in the sky. Another way to put it is that, white light (the sunlight) is dispersed as it passes through a prism (in this case, the water droplet) and created a sequence of color according to the wavelength of each color (the rainbow).

Rainbow consist of seven colors – red, orange, yellow, green, blue, indigo, and violet, from the outer part to the inner part. In some countries, school children are taught to remember the sequence of the color as R-O-Y-G-B-I-V. And if you do notice, most of the coloring tools, such as color pencils, crayons, watercolor, oil pastel, etc, are arranged in according to the sequence of the color of rainbow wherever applicable.

For those who are fascinated with rainbow appearance, you can now have rainbow with you every day on your mobile phone. Set the rainbow image as the wallpaper or background of your mobile phone. As we carry our mobile phone with us most of the time and will look at it many times in a day, a rainbow wallpaper or background will put a cheer in your mind.

To set the rainbow image in this app as the wallpaper or background of your mobile phone is easy. You just have to tap on the ‘Wallpaper’ menu and browse through the collection of the rainbow images. You can tap on the image that catches your attention to look at it on a bigger scale. Once you are satisfied, just tap ‘Done’ and you can continue browsing or if you want to use that image as the wallpaper or background of your mobile phone, tap on the small icon on the bottom right of the image to save the rainbow image into your mobile phone.

Once done, go to the ‘My Files’ or ‘File Manager’ of your mobile phone. Look for the ‘DCIM’ or Images’ folder. Within the folder, you can find the image that you have just saved. Tap on the image, and the options from your mobile phone will appear either at the top of the screen or at the bottom of the screen.
