Reading books on portable devices is always a compromise between comfort of reading and text availability. ShortBook² offers an original way of solving this problem with its careful approach to text makeup on the limited screen area of iPhone or iPad. A lot of experiments with various text compositions and interface layouts have jelled the unique match for convenient reading. If you need to read for a long time, with comfort and without any considerable damage to the sight take advantage of the ShortBook² program — a high-end reader. ShortBook² focuses on the layout process, allowing the user to control virtually all text placement options. Moreover, the program analyzes the text and places decorative elements in various places, which not only decorate the book and bring their atmosphere into it, but also simplify the reading process. Thus, in ShortBook², even "picture-free" books look attractive and do not tire with the external monotony while reading, which not only increases reader comfort, but also reduces eye fatigue from the reading process. The program fully supports FB2 electronic books format including contents, footnotes and figures. Any electronic book can be easily converted to this format with free utilities though using a variety of web libraries with books already in this format is much more simple. To meet personal preferences, the application has rich settings, including several dozens of customizable parameters. The book index has several sorting modes allowing to find a required writing easily. Reading can be quickly restarted after a break with one touch of the screen. The reader keeps reading statistics and offers developed means of monitoring the reading process. The application was developed using the latest technologies, therefore it is not available for users of iOS 12 and below. These users can use the classic ShortBook application. ShortBook² is available by subscription. The subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period. Subscribers gain access to all Short Review materials that will be published during the subscription period. Short Review materials contain reviews of the book market of electronic publications in Russia, book ratings and recommendations for organizing reading.

Your books, and the ones going around. Ex-libris is the app for your own library: what you own, where it sits, and whose hands it is in. Not a reading list — an inventory of the books actually on your shelves. BUILD YOUR LIBRARY, ONE SHELF AT A TIME Open the scanner and walk along your shelves: the camera stays up, each barcode brings the book onto the screen, one tap files it, and the next one is already waiting. A book you have scanned before says so, so a second pass never creates duplicates. You can also search for a title and add it by hand. SHELVE THEM THE WAY THEY SIT AT HOME Create shelves and drag your books onto them, on a screen built for it: your shelves on one side, the books still to file on the other, and nothing written until you confirm. If you do not know where to start, "Suggest an arrangement" uses the AI built into your iPhone to propose shelves sized to your collection. You keep the last word: the proposal touches nothing before you accept it, and never disturbs what you arranged by hand. ONE SEARCH One field, three answers: your books, your friends' books, and the inventaire.io catalogue. Your own results first, your recent searches at hand, and the option to search by title or by author. LISTS FOR EVERYTHING ELSE To read, to give away, summer crime novels, the pile by the bed: create as many lists as you like, from a book or from the Lists tab. LEND, GIVE, SELL Mark a book as available to lend, to give away or to sell, and follow each transaction with the person concerned, messages included. You finally know who has your copy — and since when. THE COMMUNITY Find your friends, browse their shelves, see what they are willing to lend, and ask them for a book instead of buying it. BUILT ON INVENTAIRE.IO Ex-libris runs on inventaire.io, the open, non-profit book database: your account and your books are hosted there, author, work and edition pages come from its open data, and what you add benefits everyone. No ads, no data resale. Happy reading — and happy lending.

Verdict

The call

The clearest difference is review sentiment: Ex at 100% against ShortBook²'s 40%. Ex also leads on monetization model (free vs subscription) and update cadence (every 4 days vs every 2 months). ShortBook²'s advantage is ratings volume (13 vs 1) and device support (4 vs 1). On price, ads and in-app purchases there is nothing between them.
