3D Atlas A new way to understand your courses: interactive scenes to explore with your fingers, from the human body to molecules, from the solar system to math figures. Encyclopedias in medicine, physics, chemistry, math, history and economics, with guided tours, fact sheets and hands-on controls to see what you study. Dark mode Oria goes dark when you want it to: automatically with your iOS setting, or on demand in Settings. A "plum night" theme designed for late study sessions that are easy on the eyes.

- Anticipate your exam: Oria predicts what's likely to come up and builds full mock exams, with correction and catch-up. - Check my calculation: circle your maths lines and Oria tells you where the mistake is and why. - Stuck? Reveal the solution step by step, and ask Oria when you don't understand.

New Agenda: your whole week at a glance, with your classes, tasks and exams. Schedule an activity (Feynman method, flashcards, quiz, podcast…) on one or more chapters, at the time and in the color you choose. LaTeX in the PDF viewer: write math by hand and get it typeset as clean, perfectly formatted formulas. Better quizzes: faster generation with questions appearing as soon as they're ready, sessions of up to 50 questions, and a "View in the course" button on every correction that takes you straight to the passage justifying the answer. Sound feedback on right and wrong answers, and a more compact layout on iPhone.

Minor visual improvements and bug fixes.

Your timetable, now in Oria. Import your timetable into the Agenda to see your week at a glance and plan your revision around your classes.

New: the Feynman Method. Explain your course out loud to a listener who knows nothing, to a classmate who missed the class, or to an examiner. They ask the questions that hurt, spot your gaps, give you a score, and you explain again. • A Feynman sheet written in your own words, saved in the chapter • Your gaps become flashcards in your daily review • Available from every chapter and from the Review tab Plus small visual fixes throughout.

A real focus corner in Oria. • Focus timer: a discreet pill counts your 25-minute sessions and breaks without ever getting in the way. • Ambient sounds: rain, nature, stream or lo-fi, playing continuously, even with the screen locked. • The timer follows you into the PDF reader as a small pill at the bottom of the screen. • On iPhone, the podcast player now tucks into the edge of the screen. • Audio import up to 200 MB: your long recorded lectures go through in one go. • Fixes: voice recordings on iPad, audio import layout on iPhone, clearer error messages.

Better handwriting, better notes. • New pen bar and a contextual palette, right where you write • Shapes straighten themselves — lines, arrows and circles snap clean • Scribble over a stroke to erase it • Handwriting cleanup for neater notes • Add videos to your notes • A lighter floating toolbar that stays out of your way

Minor bug fixes and visual improvements.

Math finally looks like your textbooks! Formulas, vectors and fractions are now beautifully rendered in your courses, flashcards, quizzes and lessons. • Scanned PDFs can now be imported (photos of notes, handouts) • Better reading of math PDFs • Various fixes and improvements

• New: Interactive Lessons! Turn any chapter into a step-by-step lesson — theory, quizzes, fill-in-the-blanks and a final quiz. • Ask Oria for help mid-lesson: your tutor reads along with you. • Visual polish and fixes.
