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.

Everything you need

The app is everything I need, I love the prediction section and how it tells me when I should expect to finish a book. I use that feature with Things to get daily reminders (I like all of my reminders in one place), I use the expected date from Leio and use it to set how many times I should be reminded.
I love Leio, many thanks for this amazing app.

New Review

I made a review when this app first released. I didn’t give it 5 stars at the time because I had a few recommendations. These included: goals. I’m so glad to see that they made this app even better than before! I literally cannot live my life without this because it helps me read the books that are collecting dust on my shelves. The design and execution of this app is genius!

Developer Response ,

Thank you! I'm working on a better Goals section as we speak. It still won't be visible in each book's page though, but I'll keep that in mind for future versions. I like the idea, but I don't want book pages to get crammed with too much information. I'll see what I can do. :)

Great app!

So far I really enjoy this app. I especially appreciate the ability to set reading goals and see my progress. If I could add this app to my iWatch I’d gladly give you a 5 star rating. Thank you.

Developer Response ,

Thank you for your review! I'm working on the watch app, hopefully it'll be available soon. :)
