Imprint's App Store name is "Imprint: Learn Visually," and that is an accurate description of what it does and of its limit. A good illustration makes an idea feel obvious in about four seconds. Feeling obvious and being usable are separated by a gap that no diagram can close on its own.
Editorial note: Iro AI is our app. Where it appears below we say so, and it has to earn its spot by the same criteria as everything else.
Decide whether you want to understand ideas or use them. Those are different products and the visual-explainer format is excellent at the first.
If you want to keep meeting big ideas across psychology, business and science and enjoy the presentation, you are in the right category and should pick on which app's writing and art you prefer. If you have noticed that you understood everything and can apply none of it, you want a practice product: Iro AI if the subject is using AI tools, Brilliant for maths, logic and computer science, Khan Academy for academic foundations at no cost.
This is not a criticism of any particular app. It is a property of the format, and it is well documented.
A well-made illustration removes cognitive load. The idea arrives assembled, you feel the click, and the feeling is genuinely pleasant. The problem is that the click is a measure of presentation quality, not of your learning. Researchers call this the illusion of fluency: material presented clearly gets rated as better learned than material you had to struggle with, and then performs worse on a delayed test. Difficulty during study, within reason, is what makes recall durable later.
Which produces the specific experience people describe when they look for an alternative: forty illustrated lessons on decision-making, complete confidence in the concepts, and no change at all in how they actually make decisions.
The fix is not a sharper diagram. It is retrieval, producing the answer yourself before you are shown it, and feedback, finding out precisely which part you got wrong. A format where you generate rather than recognise is doing something structurally different, and it is the difference that matters after a month.
Iro AI turns ideas like the ones in this post into 5-minute exercises with feedback. Free tier, Pro from $4.17 a month ($49.99 a year, 7-day free trial).
Three reasons, and the third is the honest one.
We publish what we could verify from a company's own listing and mark the rest as unverified rather than filling it in from somewhere else.
| App | Best for | What you get | Free tier | Platforms |
|---|---|---|---|---|
| Imprint | Understanding big ideas quickly | Illustrated lessons, described on its own listing as learning visually | Not verified by us | iOS confirmed. Check the store for your platform. |
| Iro AI (ours) | Using AI tools well | 29 curated paths, 477 lessons, 2,700+ exercises across 24 exercise types | Every path open, paced by a Battery that gives a lesson a day and recharges overnight | iOS and a free web app with no signup. Android in development. |
| Brilliant | Maths, logic, CS foundations | Curated interactive problem sets | Not verified by us | iOS, Android, web |
| Khan Academy | Academic foundations | Curated courses and exercises, from a non-profit | Free, with no paid tier | iOS, Android, web |
About the blank cells. Anything marked "not verified by us" is something we could not confirm from the company's own store listing or website at the time of writing. Most comparison pages fill those cells from affiliate sites, which is how a wrong price ends up repeated on twenty pages. We would rather leave a gap and send you to the listing. Check the renewal price and the cancel path before you enter a card, on any app here, including ours.
Iro is the practice half of the pair, for one subject. Same five-minute daily commitment, and it is not short of visual explanation, but the session does not end at the explanation. It ends with something you produced.
The Prompt Lab has you write a real prompt and then scores it on clarity, specificity, constraints and context, telling you which part was weak. Other exercise types have you find the fabricated citation inside an answer that reads perfectly, repair a prompt that is nearly right, or choose between two tools and learn why the other one loses. Duels run the same material under time pressure against another learner matched by rating. That is retrieval and feedback, which is the mechanism the illustrated format is missing.
The scope is 29 curated paths, 477 lessons and 2,700+ exercises across 24 exercise types, covering ChatGPT, Claude, Gemini, Perplexity, prompt engineering, agents and automation. Streaks, XP and six ranks carry the habit; the Battery paces new lessons at one a day and recharges overnight.
You can test the difference in two minutes at app.tryiro.com, which is free and needs no signup: do one exercise and notice how different it feels from finishing a lesson you only read.

It depends on whether you want to understand ideas or apply them. To keep meeting big ideas in an illustrated format, stay in that category and pick on the writing and art you prefer. To close the gap between understanding and doing, pick a practice product in the subject you care about: Iro AI for using AI tools well, Brilliant for maths and logic, Khan Academy for academic foundations at no cost.
We could not verify Imprint's current pricing or free tier from its own store listing, so we are not going to state one. Open the App Store listing and read the in-app purchase section; that is authoritative and takes half a minute. Whatever you subscribe to, check the renewal price rather than the introductory price and confirm where the cancel button lives.
It works very well for understanding an idea quickly and less well for being able to use it. A clear illustration removes effort, and effort during study is part of what makes recall durable. Psychologists call the resulting mismatch the illusion of fluency: clearly presented material feels better learned and often performs worse on a delayed test. Pair the visuals with retrieval practice and the format becomes much stronger.
Iro covers one subject, using AI tools well, and its sessions end with something you produced rather than something you read. The Prompt Lab grades a prompt you write on clarity, specificity, constraints and context; other exercises have you catch fabricated citations, repair weak prompts, or choose between tools. There are 29 curated paths, 477 lessons and 2,700+ exercises across 24 exercise types. If you want breadth across many subjects, an explainer library is the better fit.
Khan Academy is free with no paid tier. Iro AI is free to start with every learning path open, paced by a Battery that gives you a lesson a day and recharges overnight, and it runs as a free web app at app.tryiro.com with no signup at all. Compare what each free tier lets you finish, including the feedback, rather than whether one exists.
