What if I told you that you didn't need a Kindle - to have a Kindle? Well, you don't! This app by Amazon puts all the functionality of a real Kindle right onto your iPad or iPhone. Just purchase and download books right into the app and away you go! What's best about this application is that if you do have a Kindle with you, it fully syncs with your Kindle device. Read your Kindle at home while having breakfast, go to the office to work and continue reading while on your lunch break - on your iPhone or other Apple device! All this and you pick up right where you left off!. All your highlights will sync as well. The application also has the built-in dictionary that comes standard with all Kindle devices. Simply tap and hold on a word for an instant pop-up dictionary definition of the word.
As a Kindle user myself, I highly recommend getting the popular e-reader and pairing it with this application on your iPhone while on the go. But, if you aren't interested in spending the money, I must say this app does well in replacing the device itself.
Compatible with iPhone, iPod touch, and iPad.
