One scheduler. Every subject you're learning.

Chess, Mandarin, maths, UK exam prep, and more besides. One account for the whole family or just for you, each subject on its own schedule and a card due right before you'd forget it.

No card required. Nothing is shared with anyone.

The research this is built on

Retrieval practice, testing yourself on a card, is one of the most replicated findings in learning science: a review of 222 real classroom studies, not laboratory ones, put the effect at g = 0.499 across 48,478 students (Yang et al. 2021), and a separate meta-analysis of 159 comparisons found g = 0.50 (Rowland 2014). That is the mechanism behind every deck here. Chess has extra evidence of its own, below; Mandarin and exam prep are newer and share this general base without a study specific to them yet.

What a week looks like

Wednesday is missed and nothing happens. There is no streak to lose.

Practise what you are about to forget, not everything you know

One scheduler, many subjects

Chess, Mandarin, maths, UK exam prep, language vocabulary and more, each on its own schedule, in one account.

Wrong answers rest, then come back. They do not nag you five minutes later.

Miss a card and it goes to the back of the line, coming back once you are likely to have forgotten it again, not on the very next one.

A limit you set, not an endless feed

Each day has a cap on new cards and on reviews, both of which you set. When today's cards are done, the app says so and there is nothing further to do. No streak to protect at bedtime.

Chess has its own number too

Structured chess practice beats just playing by 3.6x in efficiency per hour. That number does not describe this deck though: the same study found puzzle decks made no measurable difference over playing. What moved the number was reviewing your own games. This deck rests on the general evidence above, not on the 3.6x figure.

Southwick et al. 2026, 44,213 adult players, disaggregated by activity. We make no claim about what a child gains from this deck.

What we do and do not do

We do not train AI on your data, or your child's

Reading Eggs classes AI model training alongside advertising and data brokerage. We do none of the three, for any account.

Delete it whenever you want

Write to us at any time to see what we hold on your account, or your child's, or to have it removed from our records. We do it, we do not ask why.

Everything we collect, in full

Your email and password. If your account has a child profile, a name they pick for their own screens, which can be anything and can be left blank. Which cards were answered, when, and by which profile. Which pages are visited, with no cookies and no stored IP address. That is the list.

And what we do not have

We hold no certification and display no seal. Every line above is a claim about how the app is built, and you can hold us to each one.

Who is doing the practice?

For my child

You hold the account and your child does the practice, in whichever subject they are learning. You set how much is due each day, and the session ends when that is done.

Create a free account

You choose what the account holds, and you can have it removed at any time.

For myself

Chess, Mandarin, maths, UK exam prep, and the rest of the library, same scheduler, no course to buy through first. Nobody has to be a child to use any of it.

Questions people ask

Do I, or my child, need to already know the subject?

No. Every deck has a beginner starting point, and the schedule never pushes a card far above where the learner actually is.

How long does a session take?

It depends on the daily limit you set for new cards and for reviews, in Settings. Once that is reached, the session ends.

Will it nag me, or my child, into using it?

No. There are no notifications, no streak that punishes a missed day, and no reward for coming back at a particular hour.

Does this use spaced repetition?

Yes. The app works out when you are about to forget a card and shows it to you just before that, so the ones you find hard come round more often. You do not have to think about it, and if the account is for a child, neither do they.

Who can see my account, or my child's?

You. There is no public profile, no sharing, and no way for another user to find you or them.

What does it cost?

Nothing today. Accounts are free and there is no paid tier.

Do I need to install anything?

No. It runs in the browser on whatever phone, tablet or laptop your family already has.

What subjects are there?

Chess, Mandarin, UK exam prep (11+ and GCSE), vocabulary across nine other languages, maths, and reference decks like Life in the UK and world history. More get added as they are built.

How is this different from Anki, Chessable or Lichess, for chess specifically?

Anki's own users name its interface as the top complaint across 24 million downloads. Chessable's users say a missed move gets asked again right away instead of resting. Lichess has the games and the studies, but in its own most engaged users' words, there is no way to quiz yourself on any of it. Here, a wrong card rests and comes back once you would likely have forgotten it again.
