All 450 words from the OCR Defined Vocabulary List, grouped as in the booklet. Tap a theme to open it, or drill a theme on its own.
One week, every word. Each week the app takes you through all 450 words, spread evenly across the days. Words come up in their themes, in a random order.
Type or say the meaning. Type the English in the box and press Go or Return, or tap the small microphone and say it. Any of the booklet's meanings counts, with or without "to". If you were right but it was marked wrong, tap I was right.
Inside claude.ai the page's own microphone is blocked, so the app switches to the keyboard: tap the answer box, tap the microphone key on the keyboard, say the meaning, and it submits itself when you pause. Return moves to the next word.
Missed words come back. A word you miss returns the next day, and once more two days later to confirm it has stuck. Enough room is kept in each day for these.
Weak words next week. At the end of the week the app lists the words you missed. Next week those come up three times instead of once.
The mosaic on the home screen has one tile per word. It turns gold as you get words right and red where you missed them.
To put this on your Home Screen: in Safari tap Share, then Add to Home Screen. On iOS 26 switch off Open as Web App before adding. The icon should open the app in Safari itself: iPhones do not allow speech recognition inside Home Screen web apps, so if the mic is refused there, open the same link in Safari. Progress is saved per browser, so always use the same one.
If speaking does not work, run this check on the phone and send the result to whoever set the app up.
Progress is saved on this phone only. Copy the backup text to move it to another device.
