Inside Heddy
How the app actually works — the hint ladder, the professors, the cards your own mistakes become, and the things it deliberately will not do.
Heddy is live on the App Store — and here is what it refuses to do
Heddy is now on the App Store, free to download: eight AI tutors for KS3 who will not hand over the answer, and flashcards that are free forever.
The KS3 map behind Heddy: 700 concepts, and what has to come first
Heddy teaches from a mapped curriculum — 700 named KS3 concepts and 1,147 prerequisite links across seven subjects — not a generic chat window.
Why there is no in-app purchase in Heddy
A child using Heddy can never spend money inside it. No upgrade button, no coin pack, no price on any screen they see. Here is what that costs us, and why we pay it.
Again, Good, Easy — how grading a card in Heddy works
Three buttons, each showing the real interval underneath. How Heddy's review room schedules a card, why there are only three grades, and how to grade honestly.
Eight tutors, one for every subject — who's inside Heddy
Heddy carries Mentor plus seven subject professors — Pi, Quill, Darwin, Curie, Newton, Harari and Mercator. Each teaches a different way. Here's who does what.
Getting Heddy on your iPhone — App Store or straight from the web
Two ways to get Heddy: the App Store, or install heddy.app to your home screen. What each one gives you, what works offline, and what notifications do.
Heddy or aitutors.me? Which of the two is for your family
Same tutors, two products. Heddy is the student's own door with no account; aitutors.me is the parent-provisioned service with a dashboard. How to choose.
Is Heddy safe? A parent's guide to the app your teenager found
Your child downloaded an AI tutor app without asking. Here's what Heddy does, what it records, what it will never show you, and why the age floor is 13.
Meet Heddy: the AI tutor app that won't give you the answer

No signup, no parent, no download wall — how Heddy starts
Heddy opens without an account, an email, or a grown-up's permission. Here's what happens in the first thirty seconds, and what's happening underneath.
Pi Turns explained: what's metered in Heddy, and what's free
Flashcards in Heddy are free and unlimited forever. Tutor turns are metered. Here's exactly how the meter works — and the three rules it can never break.
The Atlas: ready-made flashcard decks you can adopt on day one
The Atlas is Heddy's library of pre-built decks — every KS3 subject plus the UK academic competitions. Adopt one and it becomes yours to review and edit.
The carry moment: take a stuck flashcard straight to your tutor
The card you keep getting wrong can be carried to the professor who owns it, with the question already asked. It's the most important gesture in Heddy.
The four-rung hint ladder: why Heddy never gives the answer
Heddy's tutors walk a four-rung hint ladder. The top rung is a worked similar problem, never your own answer, and there is no fifth rung. Here's why.
What Heddy deliberately will not do
No streaks to lose, no paywall mid-session, no parent surveillance, no answer on demand. A list of the features Heddy doesn't have, and why each one is missing.
Who is Heddy? A snowy owl who is a guide, not a mascot
Heddy is the snowy owl on the home screen. She notices the week you're having, routes you to a tutor, and is carefully not built to be your friend.
Your first ten minutes with Heddy, step by step
Open the app, skip nothing, and get one real thing done. A walkthrough of the first ten minutes in Heddy — what to tap, in what order, and why.
Your sessions become flashcards — free, unlimited, forever
Heddy turns the lesson you just had into spaced-repetition flashcards. They're free, unlimited, and reviewing them never costs a tutor turn. Here's how it works.
Heddy is free to start, and the flashcards stay free forever.
