Works out of copyright, read end to end and summarised in our own words. Every jacket here is set by us, in the colour the app gives that book — not one of them is a publisher’s cover borrowed for a landing page.
Name one idea from the last book you finished.
Take your time.
Most people cannot, and it is not a failure of attention or intelligence. You read it once, at the pace of a page, and then nothing ever asked you about it again.
That is the part Mindroll fixes. Not how much you read — what survives the week.
How it works
Three things, and nothing else
The whole product is one loop. It is short on purpose: a session you can finish is a session you come back to.
01
Five ideas, picked for you
Tell it what you want to get better at and how long you have. The day’s five are chosen from 88 sources across 14 topics — arguments worth having, not headlines.
02
It ends
A session has a last page. Five ideas, about five minutes, then you are done and the app says so. There is no feed underneath it and nothing loads when you reach the bottom.
03
The ones you keep come back
Save an idea and it returns after a day, then three, then seven, then sixteen, then thirty-five. Two answers — you remember it, or you don’t. After the last one it stops asking, because you have it.
Anatomy of a card
This is one idea
Not a chapter, not a summary of a summary. A claim, the reasoning that makes it true, and something to do about it before tomorrow — with the source it came from named underneath. These are five real cards from the app.
The claim, in one line
The obstacle is information
Why it holds — the argument, kept intact
A blocked path tells you something about the terrain. Aurelius treats interference not as an interruption of the work but as the material the work is now made of. This is less inspirational than it sounds: it is a practical instruction to stop waiting for conditions to improve before you act.
Something to try before tomorrow
Ask of the current obstacle: what does this let me practise that a clear road would not?
Where it came from, always named
BookMeditationsMarcus Aurelius
The claim, in one line
The cost of a thing is the life you exchange for it
Why it holds — the argument, kept intact
Thoreau's most durable idea is an accounting one: price the purchase in hours of your life rather than currency. A more expensive flat is not more money, it is more years at a job you would otherwise leave.
Something to try before tomorrow
Before the next significant purchase, divide the price by your hourly take-home pay and sit with that number.
Where it came from, always named
BookWaldenHenry David Thoreau
The claim, in one line
You lose the ability to tell how impaired you are
Why it holds — the argument, kept intact
The consistent finding in restricted-sleep studies is not just that performance drops. It is that self-rated alertness stops dropping with it. People plateau at "a bit tired" while their measured performance keeps sliding. The instrument you would use to check on yourself is the instrument that breaks first.
Something to try before tomorrow
Do not use how you feel to decide whether you are fit for something that matters. Use how much you slept.
Where it came from, always named
TalkWhat Sleep Debt Actually DoesMira Adeyemi
The claim, in one line
Pay yourself first, before anyone else
Why it holds — the argument, kept intact
A tenth of everything earned is kept before any obligation is met. The order is the whole idea: saving what remains after spending produces nothing, because spending expands to fill whatever it is given. Saving first makes the rest the variable.
Something to try before tomorrow
Move the transfer to the day you are paid, not the day before the next one.
Where it came from, always named
BookThe Richest Man in BabylonGeorge S. Clason
The claim, in one line
The dose-response curve is steepest at the very bottom
Why it holds — the argument, kept intact
The largest gains in mortality risk appear between doing almost nothing and doing a little. Going from sedentary to a short daily walk moves the number more than going from moderately active to very active. This is the least motivating finding in the field and the best supported.
Something to try before tomorrow
If you do nothing, the useful target is not a programme. It is ten minutes, most days.

Features
What you get
Eight things the app does. No others, and none of them a roadmap item.
A feed built from your answers
Topics, a goal, a daily length, and the books you already meant to read. Not from what keeps you scrolling.
The argument, not the headline
Every card gives you the claim, why it holds, and something to try. Open “Go deeper” when one lands.
Spaced review
Only what you save enters review, and a session is capped so it always ends. Seven a day, maximum.
Listen to any of it
Every idea narrated, with background playback and lock-screen controls. Pro.
Download for offline
Keep ideas and audio on the phone for a flight or a tunnel. Pro.
Scan a book you own
Point the camera at a cover or a barcode and Mindroll finds its ideas. The barcode is read on your device and no photograph is uploaded.
A library that is yours
Save ideas, sort them into collections, and keep the notes and reflections you wrote against them.
Analytics off unless you say otherwise
Usage analytics are off by default and stay off until you turn them on. Card details never reach us: Apple handles payment.
What’s inside
Real sources, named on the page
Every idea says where it came from, who owns it and when it was last checked. There is no anonymous “distilled wisdom” here, because an idea you cannot trace is an idea you cannot check.

Where it comes from
Mindroll publishes two kinds of thing, and only two. Works out of copyright — Marcus Aurelius, Seneca, Montaigne, Darwin, Mill and others — read and summarised in our own words. And original editorial written for this app. Nothing is lifted from another product’s summaries, and every source carries its licence.
Original series
Written here. Drawn here.
The catalogue is public-domain works read properly, and original series made for this app. These are the second kind, with cover art drawn for each one.

Questions
Is this a book summary app?
No, and the distinction matters. A summary compresses a book so you can say you have read it. Mindroll takes one idea at a time, keeps the argument that makes it true, and then asks you about it again days later. You will finish fewer books here and remember considerably more of them.
Does this replace reading the book?
It is not meant to. Half of what it is good for is telling you which book is worth your next month — you read one idea from it before committing to four hundred pages. Every source is named, so going to the original is always one tap away.
What is actually in it?
88 sources — 39 of them books, the rest articles, podcasts, talks, essays and research — broken into 616 ideas across 14 topics. All of it is either out of copyright and summarised in our own words, or written for this app. Every item carries its licence and the date it was last checked.
How does the review actually work?
Only ideas you save enter review, because saving is you saying that one mattered. A saved idea comes back after one day, then three, then seven, then sixteen, then thirty-five. You answer one of two things: you remember it, or remind me. Forgetting sends it back to the start, and a review session is capped at seven so it always ends.
Will it work without a signal?
Reading works offline once the day has loaded. Downloading ideas and audio to keep permanently on the device is part of Pro.
What do you collect about me?
What the app needs to give you a personalised plan and remember your progress: your onboarding answers, what you read and save, and your subscription status. Usage analytics are off until you turn them on. We never see your card details, we do not sell anything about you, and the whole of it is set out in the privacy policy.
How do I cancel?
In your Apple account settings, in two taps, exactly like every other App Store subscription. We are not involved and cannot be a reason it fails. You keep Pro until the period you have paid for runs out.
Five minutes, and something left over.
Swap one scroll for one idea that is still there on Thursday.
