Leto is a simple and beautiful book management app that helps you to easily keep track of the books you are currently reading, would like to read or already have.


Adding books to Leto is super easy and fast. Just by scanning its barcode, the book cover, title, author and number of pages will be automatically added. You can also import your book collection from other sources such as Goodreads or Calibre.


When you add a new book, Leto allows you to specify a wide variety of details for a better description of the book. The available parameters range from the title and author of the work, to the genre, the original language of the text, whether it is written in verse or prose, identifiers such as ISBN and Thema codes, and even its dimensions and weight. It will not be necessary for you to include all that information at first, but you will have it at your disposal if you wish.


Leto allows you to create smart book collections based on a wide variety of parameters, so that you can have your books grouped according to the criteria that you consider the most appropriate. Specifically, you can keep your library organized by creating collections based on author, language, read-status, publisher, genre, and so on.


Each book you add to Leto has a read-status, which can be: “To Read”, “Reading”, “Finished” or “Left Unfinished”. Leto automatically creates different book collections based on their status so that you can have them well organized. In addition, you can keep track of your reading progress by indicating the current page of the books in question.


With Leto, you can keep all your books stored in iCloud and synced seamlessly across all of your iOS devices so you can access your library from your, iPhone and iPad.


Widgets are a great way to keep track of the books you are reading. Add to your Home Screen as many widgets as you like, each one displaying a different book. Widgets makes it easy for you to see your progress at a glance and entice you to read more.

My new favorite app!

I am the most disorganized, scatter brained individual you’ll ever meet…and my collection of nearly 600 books that are strewn everywhere is a great representation of this. I needed help!!! When I found Leto I was so excited and it did not disappoint. I am an avid reader, so getting my books cataloged has been wonderful. I have books dating from the late 1800’s to current and I have been able to get them entered, no matter the age, with the multiple data entry options available on the app. The scanning option is quick and easy, and for the older books…or those not recognized via scan, the manual option is user friendly and only takes but a minute. One of the greatest things I discovered along the way though is that if you have an issue, question or comment, Leto is more than willing to help and they are quick to respond. Trust me, that rarely happens. I will be recommending this app to all of my friends and family. Thanks Leto!

Thanks a lot for your support!

strawberry theme ,

this app has lots of potential!

best reading tracker thus far aside from the fact you have to manually add each book yourself as well as all the info which is such a pain imo BUT i love that it has ios vibe to it & displays the books exactly how i like. hopefully as the app improves overtime there will be a book dictionary/web option to add easily from but still keeping the ability to edit whatever

Hi there! Thank you for your review! You can already add books automatically without the need to fill in all the details yourself. When adding a new book, you will see two buttons at the bottom of the screen: the one on the left lets you scan the book’s barcode, and the one on the right lets you search in an online database. Email me at leto@alexgarcia.cat if you need any further help with that. :)

Please fix bug!!

This is my all time favorite book app! I use it everyday to keep track of my book collection and it’s perfect!! The only thing now is, I use the widget form of the app religiously, but it’s not working anymore. I can’t pick what books i want to have on the widget. When I click Chose, nothing happens. Please fix it soon! I love this app so much! I just started a new book and want to show it on the widget!

Hi there! I’m glad you are enjoying the app! I’ve just checked and Widgets seem to be working as expected. Email me at leto@alexgarcia.cat so I can see your case in more detail.
