Coef réunit ce qu'un élève fait déjà dans quatre apps différentes : un chrono de révision, ses moyennes, ses fiches, et de quoi ne pas travailler seul. LE CHRONO QUI DÉCIDE AVEC TOI Pomodoro, chrono libre ou minuteur. Et si tu ne sais pas par quoi commencer, Coef peut regarder tes examens, tes coefficients et le temps que tu as déjà passé sur chaque matière, puis te propose une matière — en t'expliquant pourquoi. TES MOYENNES, AVEC LES COEFFICIENTS Par trimestre ou par semestre, au choix. La moyenne générale, celle de chaque matière, et la réponse à la seule question qui compte la veille d'un contrôle : « il me faut combien pour avoir 14 de moyenne G? » TES FICHES ET TES CARTES Écris tes fiches de cours dans l'app, photographie ton cahier, et transforme une fiche en cartes de révision. Coef les fait revenir au bon moment — la répétition espacée, sans que tu aies à y penser. TU N'ES PAS SEUL À RÉVISER Ajoute tes amis avec un code. Tu vois qui est en séance en direct, le classement de la semaine, et tu peux lancer un défi. Tu choisis ce que tes amis voient de toi, et tu peux tout garder pour toi. TA SÉRIE Un objectif quotidien, et une série qui grandit tant que tu le tiens. Des gels pour les jours où la vie s'en mêle. Le calendrier de ton année, mois par mois. STATS Un onglet Stats spécialement dédié pour te permettre de suivre tes temps de révisions par matières, par jour et ton temps de travail. COEF MAX Le niveau qui ajoute le conseil du jour, les analyses avancées, le planificateur de révisions, les thèmes, les cadrans du chrono et les sons supplémentaires. Tu obtiens ces avantages en simplement faisant rejoindre tes amis sur l'app : ton premier ami invité vous donne 30 jours chacun, et chaque ami suivant 14 jours. CE QUE COEF NE FAIT PAS Aucune publicité. Aucun achat. Rien n'est vendu à personne. Le compte est facultatif : Coef fonctionne entièrement sans lui, hors ligne, et tout reste sur ton téléphone. Le compte sert à sauvegarder, à changer de téléphone et à retrouver tes amis. Sous 15 ans, Coef reste en mode local : pas de compte, pas d'amis, pas de synchronisation — et tout le reste de l'app fonctionne. *Coef est pensé pour le système français : notes sur 20, coefficients, trimestres ou semestres, spécialités, et les épreuves du bac.

About

Class Notes

Features
Read full description

Class Notes is a handwriting notebook app designed for students. Just like a 60-page paper notebook, you can organize your notes by subject or theme. You can share your handwritten pages with friends or teachers, and the recipient can directly add their own handwriting to the shared page. ■ Device Compatibility (Recommended) This app is designed for handwriting with Apple Pencil. Due to screen size, we highly recommend using an iPad. While you can handwrite with your finger or a stylus on an iPhone, an iPad provides a much more comfortable experience for writing across a full notebook page. ■ Manage Notes on a Bookshelf Find and open your class notes instantly from a wooden bookshelf design. When creating a notebook, you can choose the name, cover color (12 colors), and paper type. You can also rename it or set a photo as the cover later. The cover also displays your page progress. ■ Premium Handwriting Experience ・ On iPad, use standard Apple pen tools (Pen, Marker, Eraser, etc.). ・ On iPad, toggle "Draw with Finger" on or off. ・ On iPhone, choose from Pen, Marker, and Eraser, along with color and line thickness. ・ Undo/Redo and clear entire page (with a confirmation prompt to prevent accidental deletion). ・ Pinch to zoom in for easily writing fine text. ・ On iPad, write seamlessly in the same paper size regardless of screen orientation (portrait or landscape). ■ Paper Styles for Every Class In addition to Blank, Lined, and Grid paper, the Premium "Paper Pack" unlocks 6 more styles: Dot, Cornell, English 4-Line, Manuscript (Vertical writing), Vertical Lined, and Sheet Music. Paper styles can be set per notebook and are reflected in exported PDFs or images. ■ Share Handwritten Pages Send written pages via AirDrop or Files. Recipients can check the content, import it into a blank page in their own notebook, and add their notes directly. Perfect for sharing notes with an absent friend or getting corrections from a teacher. ・ Choose whether to include the sender's name. ・ Imported pages are marked with a "Received Page" stamp. ・ A confirmation screen appears when importing onto a page that already contains writing, allowing you to revert to the previous state. ・ Even without an existing notebook, you can create a new one on the spot to receive the page. ■ Review History via Calendar Features an "Edit History" tab to review pages by the date they were written. See at a glance when and in which class notebook you wrote. You can also check the writing history for each specific notebook. ■ Export Features (Great for Submissions) ・ Export a single page as an image. ・ Select multiple pages and export them as a single PDF. ・ Export an entire notebook as a PDF (choose whether to include blank pages). If you register your name in the settings, your name and the date will be automatically printed at the bottom of exported pages. At a glance, everyone knows who wrote it and when—perfect for submitting homework or reports. ■ Fully Functional Free Version Even in the free version, you can use all the following features within one notebook: ・ Handwriting, Eraser, Undo/Redo ・ Blank / Lined / Grid paper ・ Send and import pages ・ Export single pages, multiple pages, or the entire notebook ・ Change cover colors and photos Try it out with one notebook without any feature restrictions. ■ Premium (One-time Purchase) Pay once and use it forever. This is not a subscription. ・ Create unlimited notebooks (manage by subjects like English, Math, Science, History, etc.) ・ Unlock the Paper Pack (6 extra styles) ■ Recommended For: ・ Students who want to organize their class notes by subject. ・ Those who want to carry their handwritten notes on an iPad with Apple Pencil. ・ Users who want to easily exchange single note pages with friends or teachers. ・ Students who need to submit handwritten homework or assignments. Write naturally like on a paper notebook, share pages when needed, and export data digitally. Give it a try for your everyday class notes!
