Spark: Micro Learning

Spark is the daily reading app for people who love ideas but don't have time for a 300-page book.
Every Spark is a 3-5 minute reading on a single book or concept, broken into card-style slides with optional audio narration. Personalized to your interests through a quick quiz, curated daily , and designed to actually fit into your day.
WHAT YOU'LL FIND
• Personalized daily Sparks based on your interests
• Card-by-card reading with smooth audio narration
• Save the ones that hit, share the ones that surprise you
• Daily puzzle games — Sudoku and Parallels — to keep your brain sharp
• Friend leaderboards for streaks and puzzle wins
• Streak tracking and weekly reading goals
HOW IT WORKS
Take a quick interest quiz when you sign up. Spark uses your answers to generate readings tailored to you — philosophy, business, science, history, psychology, and more. Search for any topic and get a Spark on demand. Rate what you read so the recommendations get better over time.
SOCIAL, BUT QUIET
Add friends, see their streaks, send a nudge when they fall behind. Friendly competition without the noise. No public feeds, no algorithmic timeline, no doom scroll.
DAILY GAMES
Beyond reading, Spark includes daily Sudoku and Parallels (a Connections-style word grouping game). One puzzle a day, everyone plays the same one, friends compete on a daily leaderboard.
