What this app is. What it isn’t. What you could build.

One-liner

A lightweight, no-frills FB2 and EPUB ebook reader focused on fast loading and minimal distractions for readers of Russian-language books.

Strengths

Fast loading and smooth performance with large FB2 files (review: 'loads huge books instantly')
Excellent support for FB2 format, which is rare among mainstream readers
Clean, distraction-free reading interface with customizable fonts and spacing
Strong localization for Russian language users (keywords: 'Библиотека', 'читать книги')
No ads or in-app purchases—users appreciate the simplicity and honesty

Weaknesses

Limited to FB2 and EPUB—no PDF or MOBI support (review: 'I can't read my Kindle books here')
No cloud sync across devices (review: 'I have to re-download everything on each phone')
No built-in dictionary or text search functionality (review: 'can't look up words, very frustrating')
Outdated UI design; lacks modern gestures like swipe-to-turn-page (review: 'feels like 2015')
No audiobook support or text-to-speech (review: 'would be great if it could read aloud')

Opportunities

Add basic PDF/MOBI support while keeping FB2 as a core strength
Introduce cloud sync via iCloud or Google Drive to retain progress across devices
Build a simple built-in dictionary with offline lookup (even just a basic word list)
Implement text-to-speech with adjustable voice speed and pitch for accessibility
Create a companion web app to manage library metadata and export/import collections
