Kokzhiek Library превращает любой файл в настоящую книгу. Открывайте PDF, EPUB, FB2 и TXT и листайте страницы с реальным загибом листа — как будто держите бумажную книгу в руках. Что внутри: • Любые форматы. PDF, EPUB, FB2, TXT — открываются в одном приложении. • Перелистывание с загибом. Плавный загиб страницы с тенью и бликом — 60 кадров в секунду. • Три способа чтения. Загиб листа, мягкий сдвиг или вертикальный свиток — выбирайте, как удобнее. • Четыре темы. Бумага, сепия, тёмная и AMOLED — комфортно днём и ночью. • Своя библиотека. Все ваши книги в одном месте, с обложками и прогрессом. • Синхронизация. Прогресс чтения, закладки и избранное синхронизируются между устройствами. • Закладки и поиск. Отмечайте важные места и ищите по тексту книги. • Аккуратная типографика. Шрифты Fraunces и Literata, выверенные поля и межстрочные интервалы для долгого чтения без усталости.

Verdict
The clearest difference is monetization model: JustReader at free against Kokzhiek Library's free with in-app purchases. Kokzhiek Library's advantage is update cadence (every 5 days vs fortnightly) and iOS requirement (13.0 vs 17.0). On price, review sentiment, ads and in-app purchases there is nothing between them.
