Blinkist compresses a book into fifteen minutes. That is a genuinely good product for one job, and the wrong shape for another. Most people searching for an alternative have realised they want the second thing: not to know about a subject, but to be able to do something with it.
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.
Start by naming the job. If you want book summaries and simply want a different app doing it, Headway is the obvious swap. If you have realised that summaries are not changing what you do, you want a practice product instead, and which one depends on the skill: Iro AI for using AI tools, Brilliant or Khan Academy for maths and science foundations.
What you give up by leaving is coverage. A summary library spans thousands of titles across every subject, and no skills app comes close to that range. The trade is depth on one thing against breadth across everything.
Two reasons dominate, and the second is the interesting one.
If the second reason is yours, swapping to a different summary app will not fix it. The thing to change is the shape of the product, not the brand on it.
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).
Grouped by the job rather than by category, because the category is what people get wrong here.

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 alternative if the thing you kept reading summaries about was AI. Same five-minute daily commitment as a summary, but the session is an exercise rather than a chapter: write a prompt and get told which part was weak, spot the hallucination in a plausible answer, pick the right tool for a task and find out why the other one loses.
The structure is a curriculum, not a library. 29 paths across ChatGPT, Claude, Gemini, Perplexity, prompt engineering, agents and automation, with 2,700+ exercises across 24 exercise types. Streaks, XP and six ranks keep the habit going, which is the part Blinkist gets right and most educational apps get wrong.
Two things, said plainly.
Iro runs as a free web app at app.tryiro.com with no signup, so you can see whether the exercise format suits you before installing anything.
One question, honestly answered: do you want to know about something, or be able to do it?
Both are legitimate. Knowing about behavioural economics makes you better company and occasionally better at your job. Being able to write a prompt that gets a usable answer changes your Tuesday. They are different products and the mistake is buying one while wanting the other.
If the answer is know about, stay in the summary category and pick on interface and library. If the answer is be able to do, pick the app that specialises in the skill you named, and check that its free tier lets you try the actual thing rather than a tour of it.

It depends on the job. For book summaries with a different app, Headway is the closest direct swap. If summaries have not changed how you work and you want a skill instead, pick by the skill: Iro AI for using AI tools well, Brilliant or Khan Academy for maths and science foundations. Khan Academy is entirely free.
Khan Academy is entirely free and covers academic foundations. Iro AI is free to start on iOS with every learning path open, paced by a Battery that gives you a lesson a day and recharges overnight, and it also runs as a free web app at app.tryiro.com with no signup. Free tiers in this category differ a lot, so check what each one actually lets you do rather than whether one exists.
They work for what they are: transferring the argument of a book in fifteen minutes. That is real value if your goal is to follow a conversation or decide whether to read the full text. What they cannot do is build a skill, because reading about a practice and doing it are different activities. If you have finished dozens of summaries and changed nothing, that is the format working as designed, not you failing at it.
Only if the subject you care about is AI. Iro is not a summary library; it is a curriculum of 29 paths, 477 lessons and 2,700+ hands-on exercises about using AI tools well, in five-minute sessions with instant feedback. If you want broad coverage across every subject, a summary app is the better fit and Iro is not trying to replace it.
Three things, in this order: the renewal price rather than the intro price, the renewal date, and where the cancel button lives. If you subscribed inside an iPhone or Android app, the store holds the subscription and cancelling takes two taps in your device settings. If you subscribed on a website, cancelling happens in that site's account settings.
