It’s almost like getting paid for reading! Readercoin is an app for iPhone and Android which has thousands of e-books and audiobooks available for free. Readercoin “pays” you 1 Readercoin for every 10 minutes you spend reading or listening. Readercoins are then redeemable as rewards, such as Amazon vouchers, Kindles, and even real cash (via PayPal)! It has ratings over 4 stars on both Google Play and the iStore, has a load of free classics, and is also a great way to discover lesser-known treasures!
