ReadTracker 3 is an Android tool designed for book lovers who want to keep track of their reading progress. With this application, you can save a trail of the books you have read and add a closing remark to each one to help you remember your thoughts after reading it. Additionally, you can keep a list of your favorite quotes from each book and visualize how far and how long you read each time you picked up the book.

One of the best features of ReadTracker 3 is that it provides an estimation of how long you have left to finish the book, which can be helpful when you want to set a goal or plan your reading time. Moreover, you can share your reading history on Readmill, a web service that lets you connect with other readers and get inspiration for your next book.

ReadTracker 3 is a free application developed by Christoffer Klang, and it's a side project developed in his spare time. It's not an official part of Readmill. If you have any problems or feature suggestions, you can contact the developer via email or Twitter.
