01Structure
We split the service into six sections, each of which can be walked into directly: shop, catalogue, audiobooks, library, subscription, profile. The same title sits in the catalogue and on the reader’s shelf, but shows differently — price there, progress here.
02Catalogue
Filtering works on four things at once: genre, format, rating and subscription. Removable chips show what is filtered right now — otherwise people forget why the results are short and decide there are few books.
03Book page
One screen holds everything a purchase turns on: cover, length, translation, publisher, year, rating and whether the subscription covers it. The price and “read the first chapter” stand together — the sample comes before payment, not instead of it.
04Reader
Three themes, four typefaces, three column widths and type size. The settings are not buried in a submenu: they change mid-read, in one click, without losing the line.
05Text and audio
Switching between reading and listening keeps the place: finish a paragraph and the player starts from it. This is the core mechanic; everything else is built around it.
06Library
The shelf shows where someone left off: pages left, what is being read now, where the bookmarks and notes sit. Next to it, statistics and achievements — the things that bring people back to a book.
07Design system
One set of cards, chips, buttons and badges across every section. Shop, shelf and player are assembled from the same parts, so a new section does not have to be drawn from scratch.
