When you buy a reference book to study, you may set a target date to finish reading it. At that time, it is troublesome to calculate how many pages to read in a day. That's where this app comes in. With this app, you can record how many pages you have read each day. It automatically calculates and displays how many pages you need to read in a day, based on the number of pages remaining in the book and the number of days remaining until the target date. You can also check your reading history on a bar graph to help you stay motivated. We'd be honored if we could be of service!
