Nano Learny
The best microlearning apps in 2026, compared for developers
Disclosure: Nano Learny, listed last, is our app. We’ve tried to be fair to everyone else: each app is described by what it does well and who it suits. Prices are the in-app purchases the US App Store listed in September 2026, rounded; they vary by country and change often, so treat them as approximate and check the listing before you subscribe.
Microlearning means learning in sessions of a few minutes: a short lesson, a few questions, done. It fits the gaps in a working day, and a few minutes daily tends to survive a busy month better than a weekend course does.
But “microlearning app” covers very different things. Some teach programming from zero, some summarize nonfiction books, some help you review what you’ve already read. This guide sorts them by what they’re for, with a developer’s questions in mind.
What to look for
- Whose material is it? Most apps teach from their own curated catalog. A few work from your material: your highlights, your flashcards, the docs you read.
- How deep does it go? Beginner courses are great when you start and slow once you already work in the field.
- Does it make you recall? Answering questions and coming back to them later does more for memory than reading a summary.
- What limits the habit? Streaks help. Daily caps on free lessons can get in the way.
- How does billing work? Check the monthly price, whether a free trial converts to a paid plan automatically, and how to cancel.
Quick picks
- Learning to program from zero: Mimo or Sololearn.
- Math, logic and computer science, hands-on: Brilliant.
- Short daily practice across coding and data tools: Enki.
- Big ideas from psychology, history or business, in visual bites: Imprint.
- Nonfiction books in short form: Headway or Deepstash.
- General knowledge as a daily habit: Nibble.
- Remembering anything you’re willing to turn into flashcards: Anki.
- Reviewing your book and article highlights: Readwise.
- Turning the docs of the tech you use into daily lessons: Nano Learny (ours).

Coding lessons
These apps teach from their own courses and are built for people starting out. They’re the closest thing to a “Duolingo for coding”.
Mimo
Python, JavaScript, HTML, CSS, SQL · 110k ratings · free tier, paid plans about $10–100
Good at: a structured path from zero to small projects, with code you write in the app and a daily streak. It now also teaches AI-assisted development.
Keep in mind: it’s aimed at beginners, so a working developer will find much of it familiar. Some long-time users mention in reviews that daily limits on free lessons broke their streaks. (Artem used Mimo daily before building Nano Learny; the habit worked, but the content was too easy.)
Best for: people learning their first language.
Sololearn
20+ languages · 82k ratings · free tier, PRO about $7–13/month or $48–80/year
Good at: breadth. Bite-sized lessons and hands-on exercises in Python, JavaScript, SQL, Java, C# and more, grouped into career tracks, with an active community.
Keep in mind: beginner-level content, curated by Sololearn.
Best for: beginners who want to try several languages.
Enki
Coding, data and productivity tools · 1.1k ratings · about $8–12/month or $39–60/year
Good at: short daily practice with an assistant that explains concepts, gives hints, reviews your code and suggests examples, plus a coding playground.
Keep in mind: curated content, a smaller user base than Mimo or Sololearn.
Best for: beginners who like a coach alongside the lessons, across coding, data and AI tools.
Brilliant
Math, logic, computer science, Python · 33k ratings · Premium about $25 or $120–150 (monthly and yearly plans)
Good at: interactive problem solving that builds intuition rather than memorized formulas, from foundational math to computer science and AI.
Keep in mind: broader than programming, and Premium is among the pricier options here.
Best for: anyone who wants to strengthen math and CS fundamentals.
General microlearning
Daily habit apps for curious adults. They’re polished and easy to keep up, and the topics are general rather than technical.
Imprint
Psychology, philosophy, history, business, science and more · 56k ratings · about $16/month or $75–100/year
Good at: visual explanations of big ideas, chapters of about two minutes, and daily quizzes.
Keep in mind: the catalog is Imprint’s own; it won’t cover the tools you use at work.
Best for: broad general knowledge in short visual sessions.
Headway
Nonfiction book summaries · 117k ratings · Premium plans about $13–90
Good at: a large library of summaries of nonfiction bestsellers, to read or listen to in about 15 minutes, plus a daily session of short ideas.
Keep in mind: summaries, not technical material.
Best for: getting the main ideas of popular nonfiction books.
Deepstash
Ideas from popular books · 72k ratings · free download with in-app purchases
Good at: five-minute daily reading of curated ideas from popular books, in a calm, focused reader.
Keep in mind: curated, general content.
Best for: replacing a few minutes of social media with something you’ll learn from.
Nibble
General knowledge · 47k ratings · pricing not in our data
Good at: a daily habit of bite-size lessons on general-knowledge topics.
Keep in mind: curated content for self-improvement rather than technical depth.
Best for: adults who want a light daily learning routine.
Review what you’ve read
These don’t teach new material. They help you keep what you’ve already read, using your own cards or highlights.
Anki
Spaced-repetition flashcards · AnkiMobile: 2.3k ratings · free on desktop and Android, paid on iPhone
Good at: a highly configurable spaced-repetition scheduler, open source, with shared decks for many subjects. Plenty of developers use it for languages, APIs and shortcuts.
Keep in mind: you write the cards (or trust someone else’s deck), and writing good cards is the slow part.
Best for: anyone willing to put in the card-writing time for long-term memory of anything.
Readwise
Highlights review · 1.5k ratings · Lite about $5–7/month, Full about $9–13/month
Good at: collecting highlights from Kindle, Apple Books, Instapaper and other reading apps, then resurfacing them in a daily review in the app and by email.
Keep in mind: it works from what you highlight; there are no lessons or questions written for you.
Best for: heavy readers of books and articles who already highlight.
Turn your own docs into lessons
Nano Learny (our app)
Docs sites, articles, PDFs · iPhone, coming soon to the App Store · 5 free credits, Pro $3.99/month
Good at: turning the docs of the tech you use into a course of three-minute lessons. Paste a docs link, upload a PDF or pick a ready-made learny from the in-app store; each lesson is twelve short steps that end in questions, and key facts come back in later lessons. Code snippets stay as they are in the source, each learny has a streak and a home-screen widget, and there are no hearts or daily lesson limits.
Keep in mind: it’s iPhone-only for now (Android is planned) and not on the App Store yet. Lessons are written by a language model from your source, so a detail can be wrong; a learny made from a webpage links back to the source page. Reviews happen inside a learny’s lessons, not in a full spaced-repetition scheduler like Anki. It doesn’t teach programming from zero. One credit covers up to 20,000 words, so a big docs site takes several.
Best for: working developers who want to understand and remember the docs of a framework, language or tool, a few minutes a day. How it works
Free microlearning apps
If you don’t want a subscription, these cost nothing or have a real free tier:
- Anki is free and open source on desktop and Android (the iPhone app is a one-time purchase).
- Mimo and Sololearn have free tiers with paid upgrades.
- Khan Academy is free, with courses that include computing. It isn’t microlearning in the strict sense, but it’s worth knowing.
- Deepstash is a free download with in-app purchases.
- Nano Learny gives every account five free credits with no card, enough for five learnies of up to 20,000 words each.
- And the method itself is free: turn what you read into questions and answer them again a few days later. A notes file works.
Also worth knowing
- AI study tools such as Quizlet, Gemini Notebook (formerly NotebookLM) and Turbo AI turn your own files into flashcards, quizzes and summaries. They’re built mostly for students preparing for exams rather than for a daily habit.
- iCommit is a new iPhone app (July 2026) with five-minute daily lessons for software engineers on system design, Docker, Git and LLMs, from its own lessons.
How we put this together
We read each app’s US App Store listing in September 2026: its description, its list of in-app purchase prices and its number of ratings, and for most of them the patterns in their critical reviews. We haven’t paid for every premium tier, so the descriptions stick to what each app says it does. If something here is out of date or unfair, email support@nanolearny.app and we’ll fix it.
