Kindle is not less than a boon for readers. It enables readers to carry as many books they want to with them all the time in a small device. So if you are a bibliophile you must have it.
Now for the people who don’t want to carry an extra device along with their phone , laptop, etc. Kindle App is available on app stores where we can buy the books that we want to read on our phone or laptop. It is a great app to have as it does all the work that a Kindle device do. For example you can copy, mark, highlight the words in you app . You can even long press the word to get the meaning, just the the Kindle device. I myself use Kindle app and it is amazing .
This thing could be really useful during traveling and Even in every day use in getting you things organized.
