Libellus

Libellus is a notebook. It opens like one, it turns pages like one, and it holds one part of your life per leather tab: school, private, sport, work.

**Catch it before it is gone**

Write, dictate, photograph the board or scan a handout. A line at the top of the page list becomes homework with a date — "Maths 4.12 by Friday" is enough. The widget, Siri and the Action button start a page from the Home Screen.

**Write the way you like** Type, or write by hand with Apple Pencil. A dot in the margin becomes a bullet, a circle becomes a tick box, a star becomes an action you can tick off — in the note and in the homework list at the same time. Draw on a picture or a PDF. Blank, lined or squared paper, per subject.

**Find it again** One search across every tab: pages, pictures, tables, formulas and homework. Ask a whole question and Libellus answers from your own notes — and says so when the answer isn't there. It all happens on the device.

**School, all the way through** Your timetable, the school's calendar by subscription (Aula, WebUntis, Wilma, itslearning and the rest), flashcards from your own notes, a reading plan before a test, and a recording of the lesson when writing can't keep up.

**Maths, physics and chemistry** Write a sum on a line and the answer appears in the margin. Tables with charts and a straight line through the points. A curve from an equation, with crossings, turning points and the area underneath. A formula book that solves for whichever letter you leave empty — area and volume, triangles, percent and growth, motion, energy, heat, pressure, electricity and chemistry. Circuits worked out in full, not just Ohm's law. Reactions balanced and molar masses weighed. Formulas set the way they are printed, with the symbols a tap away.

**Yours, and nobody else's** Everything lives in your own iCloud and on every device you sign in on. Nothing is sent to us. Lock a tab with Face ID.

**Free and Pro** Free Libellus gives you three tabs and ten AI helps a month. Pro removes both limits and adds the maths, physics and chemistry tools, lesson recording, flashcards, test plans and the year book. Pro is one purchase, not a subscription — and Family Pro covers up to six people.

Eleven languages for the app, and your own writing language for dictation, handwriting and text in photos.
