Take control of your reading life. Use Leio to time your reading sessions and stay motivated.

How 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.

Fun fact:
Leio means “I read” in Portuguese.


Leio 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.

Time 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.

Keep 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.
New: add new books easily with Leio's barcode scanner!

Leio 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.

If 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.

Tell 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!

Leio 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!
New: export your data to have even more control over your information.

Share your progress with friends or save reports for yourself. Now you can also sync your progress to Goodreads and post status updates!

Love it buuuttt want some change

I have been using Leio for about a year now and every time i undownload it bc it made me mad for example it doesn’t save any of my previous content. Maybe if there was a log in that would fix it. I use this a lot for school and mainly during the summer to bring up my lexile and reading speed. It would be awesome if there was a feature like that to tell me what my wpm is based on the timer and the amount of words in the book. I also play sports so it’s hard to read as much as i want or need. It would be cool if there was a notification to tell me what time would be most convenient with my schedule and for how long so I can keep my brain exercised. It would be neat if there was a feature to tell me like what books would be good for me to improve my speed and based on what i’ve read before. Something I think you guys could do different is to allow users to write notes while they read ( keep the timer going kinda setting) or star that place. Thank you i don’t really write reviews that often but i love your app i use it as much as i can along with Tide Focus timer which i really like as well during my reading hours! have a great day!! 😊😊

Thank you, your review means a lot! I'll take your suggestions into account. Note that you can already add notes while reading, just tap the Compose (little notepad) button in the upper right corner during a reading session. The timer stops automatically while you're adding the note, but that behavior can be changed at the Settings section, in the More tab (toggle the "Auto Stop" switch). I'm also not sure what you mean when you say that the app doesn't save any of your previous content. Write us at and I'll be happy to assist. :)

This is by far my favorite app!

I am an avid reader with a short attention span—I tend to start 4 books and forget where I left off. On a whim, I searched for an app to help track all of my reading and came across Leio. Wow oh wow, has it ever changed the way I read! While I refuse to convert to digital books, I love the way Leio lets me take my notes and record my favorite quotes so easily. My very Type-A personality lives for this app. I particularly love the new(er) addition that allows you to photograph the quote you’d like to record and converts it into text.

I recently contacted the support team with a recommendation and received a very kind response within the hour (!!!) I am so impressed with everything this app has to offer and the attentiveness of the developers.

Incredible. Simply Put.

So simple. So sleek. Has tremendously increased my reading. I love how you are able to see the rate at which you are reading and the projected time left to complete the book. Being a math guy I love the statistics part of the app that shows you your reading statistics over the week, month, year and all time. This is just an incredible app that if you like to read, will cause you love it even more!

If there is one thing I would suggest, it would be on the statistics page when looking at the line graph showing the time read for each month over the course of the year to be able to see the exact time read (number of hours & minutes) for each specific month.
