See it, don't just read it. More than a thousand new diagrams explain the idea behind the answer, from hydrogen bonds to the unit circle. Tap any of them to zoom in. Maths that looks like maths. Fractions, roots, integrals and powers are now properly typeset in questions and explanations. A formula booklet for every subject. Every formula is explained letter by letter, with the values that matter, what the answer means, and a worked example. Open it while you answer a question. Your mistakes come back. A question you get wrong returns the next day, then after three days, then after a week, until it sticks. Apple Pencil on iPad. Write on the question and work things out on scratch paper beside it.

Heptavo has a new look, built around the heptagon and the five-rung ladder from recall to exam level. Also new: • iCloud sync. Your answers, study sets and classes follow you between iPhone, iPad and Mac. • Exam countdown. Pick your session and Home counts the days. • Test dates. Give a study set the date of your class test and Heptavo counts down to it. • Daily reminder. One a day at a time you choose, and none on a day you have already practised. • A widget for your Home Screen and Lock Screen. • A sidebar on iPad. • Heptavo for Mac. Pro bought on one device is Pro on all of them.
