Iro AIIro AI Blog
Almost every "best microlearning apps" list you have read was written by one of the apps on it. So was this one. Rather than pretend otherwise, here is how to read a roundup published by an interested party, and then an honest comparison you can check yourself.
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.
By subject, as always. Iro AI if you want to get good at using AI tools. Brilliant for maths, logic and computer science. Khan Academy for academic foundations with no bill attached. If you want general-knowledge microlearning for its own sake, you are already in the right category and the choice is a matter of taste.
The more useful thing this page can give you is not the list. It is a way of reading every other list you are about to open, including this one.
Search for the best microlearning apps and look at who owns the pages that rank. In our own check of that result page, the top results were app blogs: nibble-app.com, nerdsip.com, chunks.app, morso.app, plus a couple of affiliate sites and a Medium post. No newspaper. No independent consumer publication. Every ranking page was published by a company selling one of the products on it.
That is not a scandal, it is what happens when a category has no editorial gatekeeper. But it means the ordinary reading of a listicle, that someone impartial compared these and picked a winner, is false in almost every case. Three tells tell you whether a conflicted roundup is still worth reading.
Undisclosed self-ranking is the whole problem. A page that tells you in the first paragraph that it is published by one of the apps has at least given you what you need to discount it.
A genuinely useful comparison names the cases where its own product is the wrong choice, and means it. If every reader path terminates at the publisher's app, you are reading an advert with a table in it.
Look at the prices and ratings. Are they sourced, dated, and consistent with the store listing you can open right now? A large share of the numbers circulating in this category originate on affiliate pages and get copied between roundups until five sources agree, which is one unverified claim repeated five times.
Applying that to this page: it is published by Iro AI, which is disclosed above and again below. It recommends Brilliant and Khan Academy over Iro for anything that is not AI skills, and tells you to stay in the general microlearning category if breadth is what you want. And it marks every cell it could not verify rather than filling it in. You should still discount it. We would rather you discounted it knowingly.
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).
The usual three for this category.
Per tell three: everything below is either published by the company or observable in the product, and everything we could not check ourselves is marked.
| App | Best for | What you get | Free tier | Platforms |
|---|---|---|---|---|
| Chunks | General microlearning | Short daily microlearning sessions | Not verified by us | Not verified by us |
| 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.
One slot, and we will not argue for more than that. If you want to get good at using AI tools, Iro is a curriculum rather than a library: 29 paths across ChatGPT, Claude, Gemini, Perplexity, prompt engineering, agents and automation, with 477 lessons and 2,700+ exercises across 24 exercise types.
The sessions are doing-shaped. The Prompt Lab has you write a prompt and then scores it on clarity, specificity, constraints and context, telling you which part was weak. Others have you catch a fabricated citation in a plausible answer, or pick between two tools and find out why one loses. Duels match you against another learner by rating. Streaks, XP and six ranks handle the habit; the Battery paces new lessons at one a day and recharges overnight.
The honest test is not reading this page. It is opening app.tryiro.com, which is free and needs no signup, and doing one exercise.

Pick by subject. For getting good at using AI tools, Iro AI: 29 curated paths, 477 lessons and 2,700+ hands-on exercises in five-minute sessions. For maths, logic and computer science, Brilliant. For academic foundations at no cost, Khan Academy. If what you want is general-knowledge microlearning for its own sake, the category you are already in is the right one and the choice comes down to taste.
We could not verify Chunks' current pricing or free tier from the company's own listing, so we are not printing a figure. Check the store listing directly and read the in-app purchase section. As with everything in this category, look at the renewal price rather than the introductory price, and find the cancel path before you enter a card.
Read them sceptically. On the result page we checked, every top-ranking roundup was published by a company selling one of the apps it ranked, including ours. That does not make them worthless, but it does mean three checks are worth running: does the page disclose who owns it, does it ever recommend a competitor over itself, and are its prices and ratings ones you can confirm on the store listing right now?
Iro AI did, and Iro is one of the apps recommended on it. That is the same conflict every other roundup on this query has; the difference is that we are telling you. Judge the page on whether it sends you elsewhere when elsewhere is right, and on whether it publishes facts you can check. For anything that is not AI skills, this page recommends other apps.
Scope and session shape. Iro covers one subject, using AI tools well, across 29 curated paths and 2,700+ exercises rather than a broad library. And its sessions ask you to produce something and then tell you what was weak about it, including a Prompt Lab that scores prompts you write on clarity, specificity, constraints and context, and head-to-head duels matched by rating. It runs on iOS and as a free web app at app.tryiro.com with no signup.
