## Review summary

KyBook 2 is praised for stability across devices, iCloud syncing, and strong readability features (font/background options, TTS). It supports PDFs/ePubs with flexible reading modes and offers a useful free option. Common drawbacks include reliability issues and crashes, intrusive upsell prompts, clipboard privacy concerns, and rough library/import workflows. Several reviews cite developer neglect and broken synchronization after upgrades. Overall, it remains appealing for accessibility and legacy-device users, but ongoing support concerns temper its reliability.

### Cons
