Blinkist condenses non-fiction books into 15-minute reads or listens called "Blinks." Each summary captures key insights from bestsellers across business, psychology, science, and self-improvement categories. Users can read text, listen to audio narration, or switch between both. The app targets professionals and lifelong learners who want to consume more ideas without committing hours to full books — positioning itself as a discovery tool that helps users decide which books deserve deeper reading.

Blinkist's interface mirrors the calm aesthetic of a premium reading app rather than a productivity tool. Typography is optimized for extended reading with adjustable font sizes and a dark mode that reduces eye strain. The audio player integrates seamlessly — users can start reading, switch to audio during their commute, and the app tracks progress across formats. Category browsing uses editorial curation over algorithmic feeds, with themed collections ("Books for Entrepreneurs," "Understanding Habits") that guide discovery. Progress tracking gamifies learning without feeling childish.

• **Read/Listen Toggle**: A persistent toggle lets users switch between text and audio without losing their place. The app syncs progress across formats, acknowledging that learning happens in different contexts throughout the day.

• **Key Insights Highlights**: Each Blink surfaces 3-5 "key insights" as pullquotes before the full summary. These act as hooks that preview value and help users decide whether to commit to the full 15 minutes.

• **Streak Tracking**: Daily reading streaks and yearly book goals create accountability. The gamification is subtle — motivating consistent learning without pressuring users with aggressive notifications.

• **Offline Downloads**: Users can download Blinks for offline reading/listening. The download interface shows clear progress and storage usage, respecting that users may have limited device space.

• **Save to Library**: A simple bookmark saves titles for later. The library separates "In Progress," "Finished," and "Saved" states, helping users manage their reading backlog without losing discoveries.
