About Flashbook: Book Summaries
Understand any bestselling book in 20 minutes — read it or listen to it.
Flashbook turns the world's best self-help, business and psychology books into clear 20-minute summaries you can read or listen to. Commute, gym, dishes, a short break: every gap in your day becomes learning time.
———————
WHAT YOU GET
• Read or listen — every book summary comes as text and as audio, with natural, professional narration. Start reading on the train, finish listening in the kitchen.
• 20 minutes, all the key ideas — we keep every important insight and drop the filler. The whole argument of the book, none of the padding.
• 14+ categories — Mindset, Career & Success, Money & Investing, Productivity, Psychology, Mindfulness & Happiness, Personal Development, Parenting, Motivation and more.
• New summaries every day — the library keeps growing, so there is always something to pick up.
• Like a podcast, except it is a whole book — download a summary, listen offline, and finish it before you arrive.
• Made for you — save favourites, get personal recommendations, and pick up exactly where you left off.
• Bestsellers you already know — Atomic Habits, The 5 AM Club, Rich Dad Poor Dad, Ikigai, The Wim Hof Method and 500+ more.
• Easy to apply — the lessons are simple to understand and put to use in everyday life.
———————
HOW IT WORKS
1. Pick a book — browse the categories, or start from recommendations built around what you already read.
2. Read it or listen to it — 20 minutes, text or audio, and you can switch between the two without losing your place.
3. Use it — every summary is built around what the book actually asks you to do, not only what it says.
———————
WHO IT'S FOR
People who want to keep learning and have no time to read. Founders and managers going through business and money books between meetings. Students using summaries to study faster. Anyone with a shelf of books they meant to read and never opened, who would rather finish one on the commute than feel guilty about all of them.
———————
WHAT READERS SAY
"It replaced my doom scrolling."
"Perfect for listening in the car."
"I finally get through the books I never had time for."
"The lessons are easy to understand and implement in everyday life."

Flashbook: Book Summaries downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. iPhone downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
