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.

Four shapes: a sticky note to remember, a speech bubble for something said, a thought bubble for an idea offered and not demanded, and a notice everybody must read. The shape is the decision — it is what makes the board readable from across the room — and any of them can carry a picture or a file. "Important" holds a pin at the top for a fortnight and then lets it stop shouting. A pin can be for one person, and "put it on their to-do list" makes it a job on their own, with who asked and who ticked it off. It goes both ways with your book, and it is not a chat, on purpose: nobody waits for a reply, and you read it on the way past. Your week is your own again A child's ordinary school day no longer writes itself across your calendar. It is there when it is out of the ordinary — a trip, a day off, a week on its own timetable, something for the bag — and quiet otherwise. Their own week still holds every lesson. The shopping list, to somebody who hasn't got Libellus Send the list as plain words, by message or mail or anything else that carries text. Only what is still to buy, in the order you walk the shop, and who it is from — for the neighbour who offered, or a grandparent going past anyway. One way, on purpose: a reply is a message, not a tick. School words only where there is school A tab for private things offered to add a "subject". It offers a section now, and says section everywhere else too. And having children no longer makes your own errands homework: a task on that list has no child on it, so your own tabs decide what it is called. The question that gives a page the formula book, tables, curves and circuits is asked in every tab now, as "Calculation tools" outside school. A section called Calculations gets what a maths lesson gets. Find anything, not just your notes Search read your pages and your homework and called it everything. Now it finds the thing itself: the party in the calendar, the milk on the list, a course on a wish list, a child, a subject, a holiday, a tab. Each in its own group, soonest first. A locked tab stays out. The week, on the Home Screen A new calendar widget. Seven days across, today circled, a dot for each thing on. School holidays are blue and your own amber, and a day that is both is drawn half and half — never red and green, so it reads for eyes that cannot tell those apart. And the shopping widget has a microphone: one tap and you are dictating. Ask somebody to an event, and see who is coming Tap an event and there is a guest list on it: who was asked and what they answered — coming, maybe, can't, still to answer — with the count out on the line in the day. "Ask somebody to come" opens your own calendar's invitation sheet, so it reaches people whether or not they have Libellus. You are told when they answer, and if they change their mind. Apple's Calendar says nothing when a reply lands; this reads it. Settings, in eight rooms Twelve sections in one scroll are now eight named rooms: the book, family and children, reading, reminders, language, Apple Intelligence, Pro, about. Everything about the family sits inside one of them — the circle, who is in it, who was invited and never answered, each child and whose phone they are on, what is shared, and the board's switch — instead of spread across Settings, the shopping list and a tab of its own. And the sample of a handwriting sits directly under the picker that chooses it, not four rows below. Calmer along the top ### Find anything, not just your notes — 2026-10-29 he family notice board A new Board tab, there as soon as somebody else is in the circle. Four shapes to pin up: a sticky note for something to remember, a speech bubble for something said, a thought bubble for an idea offered and not demanded, and a notice everybody has to read. The shape is the decision — it is what makes the board readable from across the room — and the banner says which shape went up, because a note and a notice are not the same amount of attention. Any of them can carry a picture or a document. "Important" holds a pin at the top for a fortnight and then lets it stop shouting; one that sits there for a month is one nobody reads. A pin can be for one person, with their name on it, and then "put it on their to-do list" makes it a job on their own — with who asked, and who ticked it off. To the whole family it deliberately does not become a to-do. It goes both ways with your book: put a page up on the board, or keep something from the board in your book. And it is not a chat, on purpose — things keep their shape, nobody is waiting for a reply, and you read it on the way past. Find anything, not just your notes Search used to read your pages and your homework, and call it everything. Now it finds the thing itself: the party in the calendar, the milk on the shopping list, the pottery course on a wish list, a child, a subject and the days it falls on, a holiday, a tab. Each in its own group, soonest first. A locked tab stays out, the way your pages always have. The week, on the Home Screen A new calendar widget. Seven days across, today circled, a dot for each thing on. School holidays are blue and your own are amber, and a day that is both is drawn half and half — never blended and never red and green, so it still reads for eyes that cannot tell those two apart. The large size lists what the days actually hold. And the shopping list widget has a microphone: one tap and you are dictating onto the list. Week numbers where you pick a date A Danish school says "uge 7" and never a date. Every date you choose now shows which week it is, and the calendar that opens has the week numbers down the side — so the Monday of week 42 is one tap, not a counting exercise. Emptying a timetable Until now a timetable came out one square at a time. There is a bin in the timetable now: this week only, which leaves the ordinary one underneath, or the whole thing. It counts the lessons before it asks. And when you read a new timetable off a photograph, Libellus asks whether to lay it on top or replace what is there — last term's Thursday no longer hides behind this term's. The family circle says what is happening You are told when somebody joins, when somebody leaves, and when an invitation has sat unopened for a week. Each child shows whose phone they are on, and tying a child to their phone is now in one place with the plain words for what it does — a child sees their own week and ticks off their own things; a grown-up looks after the timetables. Everyone has a face: a photograph if they choose one, their initials in their own colour if they do not. Ask somebody to an event, and see who is coming Tap an event in the day and there is a guest list on it: who was asked and what they answered — coming, maybe, can't, still to answer — with the count on the line in the day. "Ask somebody to come" opens your own calendar's invitation sheet, the same one as in Apple's Calendar, so the invitation is sent by your account and reaches people whether or not they have Libellus. And you are told when somebody answers, and again if they change their mind. Apple's Calendar sends nothing when a reply arrives; this reads it and says so. Tabs that are not school A tab for private things offered to add a "subject". It offers a section now, and says section everywhere else too. Danish, Norwegian and Swedish said the same thing two ways on one screen. One word per thing now. ### Bug fixes to Shema setup and Calendar view — 2026-10-27 Bug fixes to Shema setup and Calendar view ### Fixed bugs — 2026-10-26 The school calendar, read for you Subscribe to the class calendar once and Libellus keeps it. The same lesson posted six times shows up once. A calendar you attach to a child moves into that child's week instead of filling everyone's day. Six identical calendars, one per child, are spotted and offered as one. And the token in a school link — the part that is really a password — now lives in the keychain, not in the calendar's address. Paper, photographed Photograph the timetable at any angle. It is turned the right way up before it is read. Three shapes of timetable are understood, not one. Your notes survive a new timetable. A lesson that moved keeps what you wrote on it; a lesson that was renamed keeps it too, with the old name in front. An invitation can be taken straight with the camera, given to one of the children, and opened again afterwards — with the photograph it was read from still on it. A timetable or a letter can be picked from a shared iCloud folder as well. A year plan from the class is read in one go: days off, whole weeks and the dates with attendance. Where the paper gives a weekday as well as a date, the weekday decides the year. A week letter with nothing to do in it is no longer thrown away. It is kept as a page, on the week it is about. Holidays School holidays and your own holidays colour the days in the year calendar, the month and the day — in two colours when a day is both. A holiday written for one child reaches a brother or sister at the same school. Tables Tables can be lifted off the column and laid anywhere on the page, like a photograph. Columns can be widened, rows made taller, and a cell can be ticked, circled or crossed. Tables now come out in the PDF as well, which they did not before. Also Meetings in the school calendar give you a reminder the evening before. An event you already wrote down yourself is not shown twice when the school posts it too. A book you keep for private things or work no longer talks about homework, the blackboard or tests. On the Mac, a school token could not be stored in the keychain at all and quietly stayed in the calendar's address instead. Fixed. The ticks beside your workings no longer run off the edge of a narrow screen. ### 1.0 — 2026-10-24 No release notes. ## More apps by Mikkel Zinklar Zinglersen - [Capture Snagging & Walk downs](https://appshunter.io/ios/app/capture-snagging-and-walk-downs/id6759294087) - [StackStore Family](https://appshunter.io/ios/app/stackstore-family/id6760416852) - [Capture Log](https://appshunter.io/ios/app/capture-log/id6776244026) - [Capture Planning](https://appshunter.io/ios/app/capture-planning/id6799711943) All apps by Mikkel Zinklar Zinglersen: https://appshunter.io/developer/1877912331 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
