SquareCatEducation app development for web and mobile
We design, build and ship learning products: courses and lessons, spaced-repetition flashcards, quizzes, exam prep and learning games. We run apps like these ourselves, so yours starts from what already works.
Everything a learning product needs
Courses and lessons from your content
Bring a library of written material and we'll turn it into courses, lessons and quizzes, with an importer so your authors keep working where they already do. Lessons can be split into short steps, with reading settings learners control.
Spaced-repetition flashcards
Study sessions that bring each card back just before it's forgotten, public decks people can discover, and multiple-choice cards alongside classic flashcards.
Quizzes, diagnostics and exam readiness
A short diagnostic that shows a new learner where to start, practice questions weighted the way the exam is, and a readiness score per topic, where one weak area blocks 'ready'.
Learning games
Games that run on the learner's own material, balanced by simulation before anyone plays, and scored so they can't become a shortcut up the leaderboard.
Progress, streaks and badges
Progress pages, study streaks and achievements built from the learner's answer history, so the numbers always match what they actually did.
AI-assisted content, with review
Generating decks from notes, suggesting more cards and fact-checking content, with a person approving every change and usage capped so costs stay predictable.
Premium content and subscriptions
Free samples in every topic, locked lessons that stay visible so people can see what they'd get, and subscriptions when you're ready to charge.
Web and mobile from one platform
A web app and an Android app that share accounts and progress, and a platform that can launch a second learning product without forking the code.
Learning apps we've built and run
BraineosRebuilding a long-running flashcard platform for the AI era
A full-stack rebuild of Braineos, a spaced-repetition flashcard platform, with AI deck generation, subscriptions, an Android app and a connector for AI assistants.
FinscapeTurning one app into a multi-site learning platform
Reworking the Braineos codebase so one deployment per site can launch a focused learning product, starting with Finance Brain, a free financial literacy course site.
CertBrainExam prep where every question has a source
CertBrain, a study app for the AWS Certified AI Practitioner exam, launched on the web and Android as the third product on one learning platform, with content held to a sourcing standard.
Brain DefenseA flashcard game, balanced by a bot and shipped as its own app
Brain Defense, a tower defense game where the gold comes from answering flashcard questions, built for the Braineos web app and then released as its own Android app without writing a second game.
A studio that builds for learning
We run learning apps ourselves
Our own flashcard, course, exam prep and game apps are live and maintained by us. We've already met the problems your learners will hit, and fixed them in production.
Content is treated as the product
In education, a wrong answer costs trust. We build in sourcing, review and status tracking for every lesson and question, not just the screens around them.
Private by default
We collect only what learning needs and say plainly what happens to it. A diagnostic can work without an account and store nothing at all.
From idea to app store
Design, web, mobile, infrastructure and Google Play publishing, handled end to end by the person you talk to.
Questions about education apps
Can you turn our existing course into an app?
Yes. That's how our own course sites started: structured written content imported into courses, lessons and quizzes. We'll look at what you have and suggest the simplest way in.
Do we need both a web app and a mobile app?
Not always. Many learning products start on the web and add Android once people use them. We build both from one platform, so starting with one doesn't block the other.
Can we charge for some of the content?
Yes. We can keep samples free, lock premium lessons while keeping them visible, and add subscriptions when you're ready.
How much does an education app cost?
It depends on scope, so we don't publish fixed prices. Tell us about your learners and your content, and we'll come back with an estimate or a smaller first version that fits your budget.
