Use Leio to time your reading sessions and stay motivated.\n\nHow many books did you start this year? How many did you finish? How long did it take to read them? Leio can help you answer these questions and many more.\n\nFun fact:\nLeio means “I read” in Portuguese.\n\n---\n\nLeio is a digital journal to help you track and manage your reading. It's designed primarily around physical books, but you can also use electronic readers or other devices. Leio helps you organize your library, your notes and your favorite quotes, but that's just the beginning. Timing your reading sessions makes it easier to set aside some time and turn reading into a habit. The data gathered this way quickly turn into an extensive record of your reading life, providing you with statistics and information about your habits. These data can also be projected into the future: Leio will tell you when you will finish each book and help you plan accordingly.\n\nTIMER\nTime your reading sessions and gain insight into your habits. Life can be distracting: use Leio to set aside some time and focus on your reading.\n\nPROGRESS\nKeep track of where you are in multiple books. A quick look will tell you what page to read next, what percentage of the book you have completed, how long you have read it for and much more.\nNew: add new books easily with Leio's barcode scanner!\n\nPREDICTIONS\nLeio will learn from your habits and give you accurate predictions to help you manage your reading life. Know exactly when you will finish a book and for how long you have to read until you are done.\n\nDEADLINES\nIf you need to finish a book by a certain date, Leio can tell you how long or how many pages to read per day to finish in time. You can also play with the settings and come up with your own reading plan: tell Leio how much and how often you plan to read and see when you might finish in real time.\n\nPLANNER\nTell Leio how often you want to read each book and use the planner section to stay on track. See how much you have read on each day, how much you still have to read, and how much time to set aside to accomplish your goals!\n\nACHIEVEMENTS\nNew: Complete achievements to unlock exclusive iMessage stickers!\n\nNOTES AND QUOTES\nEasily save and search your reading notes and always have them at hand. Share them with your friends or social networks.\nNew: use Leio's text recognition service to save and share your favorite quotes even more easily!*\n\nSTATISTICS\nCheck how your reading life evolves over time. Charts and data for different timespans will help you stay motivated to read more and more.\n\nARCHIVE\nLeio will keep an extensive record of your reading sessions, so you will always be able to tell when you started a book, when you finished it, how long it took you to read it, over how many days, how many sessions and much more. Keep track of how much you have read and challenge yourself to read more. Your finished books can be searched or filtered by tags and ratings, so your information is always easy to find!\nNew: export your data to have even more control over your information.\n\nSHARE\nShare your progress with friends or save reports for yourself. Now you can also sync your progress to Goodreads and post status updates!\n\n---\n\n* Choose between a monthly or yearly auto-renewable subscription.
