How do I get Heddy on my iPhone?

Two ways. Search Heddy: AI Tutor on the UK App Store, or open heddy.app in Safari and use Share then Add to Home Screen. Both open into the same product with no account required.

Does Heddy work offline?

Flashcard review does, once the app has loaded your decks — that half is designed for a bus with no signal. Tutor conversations need a connection, because they are a live conversation with a model rather than stored content.

Is Heddy available outside the UK?

No. It is UK-only and 13+, on both the App Store listing and the web. The tutors teach the UK curriculum, and the age and data rules the app is built around are the UK ones.

Getting Heddy on your iPhone — App Store or straight from the web

There are two ways to get Heddy, they open into the same product, and neither asks you for an account.

Option one — the App Store

Search Heddy: AI Tutor on the UK App Store. Seller: aitutors.me.

Tap Get, open it, and you're on the first of three introduction slides. No sign-in sheet, no email field, no Continue with Apple.

The App Store version gets you two things the web version can't:

Notifications — a single, quiet reminder that cards are due, on a schedule you set. Never a streak threat, never "you haven't opened Heddy in three days", never anything designed to make you anxious about it. If you don't want them, don't grant them; the app doesn't ask before you've seen the product, and it works fine without.

Purchases through Apple, if you ever want more tutoring than the free allowance carries — which on a family device means Apple's own Ask to Buy applies, and a parent approves it the way they'd approve anything else.

Option two — install it from the web

Open heddy.app in Safari, tap the Share button, then Add to Home Screen.

You get an icon that behaves like an app — full screen, its own window, no browser chrome. It's the same product; it just arrives without going through the App Store.

This is genuinely useful in two situations: you're on a school or family device where you can't install from the App Store, or you want to try it right now on a link a friend sent you without downloading anything.

What works without a connection

Flashcard review does, once your decks have loaded. That half of the app is designed for a bus with no signal — the cards and the schedule are cached on the device, so you can do your daily twenty in a tunnel and it syncs when you're back.

Tutor conversations don't. A session with Professor Pi is a live conversation with a model on a server, not stored content, so it needs a connection. There's no honest way around that, and an app that pretended otherwise would just fail confusingly.

That asymmetry is worth knowing when you're planning a journey: cards travel, tutors don't.

Which one should you use

If you can install from the App Store, do — the notifications are genuinely useful for a review habit, and daily reviews are the part of this that compounds.

If you can't, or you just want to look, heddy.app is not a lesser version. It's the same eight tutors, the same Atlas, the same unlimited free cards.

What to know before you start

It's UK-only, 13+. Both are real limits rather than a rollout in progress. The tutors teach the UK curriculum — KS3 and the run-up to GCSE — and the age floor is deliberate.

Nothing is asked of you up front. No email, no card, no permissions before you've seen anything.

Bring a real problem. The app is much better at helping with tonight's actual homework than at demonstrating itself to a curious visitor. The ten-minute walkthrough is here.

Then you already have more than Heddy gives you — a parent dashboard, termly reports, subject seats for each child. Heddy is the student-facing, no-account door to the same tutors; the two products are built for different situations, and it's worth two minutes to work out which one your household actually wants.
