This release is about the reading and the buying — the two places where the app was quietly rough. • Long worked lines are broken across lines where that keeps them readable, so far fewer of them run past the edge of the screen; the remaining long ones still scroll sideways • On iPad the text and buttons in the main flows are sized for the screen rather than stretched from the phone layout • The unlock sheet shows the price before you buy it, and tells you plainly if the price cannot be loaded • Restoring a purchase now settles the app's state either way, so a restored or a refunded purchase is reflected correctly

Learning has been rebuilt around one question: do you know this first move yet? • Cards: one first move at a time — mark it Got it or Again, and anything you mark Again comes back • Practice questions hide the four options until you are ready (or a few seconds pass), so you decide first • Every answer screen lets you open the full working, and the results screen reopens any question • New: the Poisson distribution, continuous random variables and combinations of random variables (9709 Paper 6) • Tidier navigation, a clearer paid/free boundary, and tables now render properly in questions
