Klapp is a simple and intuitive solution that simplifies and digitalizes the communication between school, parents and students. Klapp allows the transmission of messages and files in private messages or as a chat. School appointments and absence messages are clearly displayed in the calendar, which can also be synchronized with the local calendar app. Video conferencing is integrated into Klapp. Printed letters, chain telephones, information booklets, absence notification via phone and a clogged pinboard are a thing of the past.

About

Coursor

Read full description

Coursor turns any topic, or your own notes, into a course built for you. Type what you want to learn, choose your level and your goal, and Coursor writes a structured course: modules, lessons, quizzes and flashcards. Python or philosophy, Italian or guitar, statistics or public speaking. A COURSE, NOT A CHAT ANSWER • Lessons in order, each one building on the last • Lessons made of clear parts: explanations, key points, worked examples, tables, formulas, code and diagrams • A quiz after every lesson, with multiple choice, fill in the blank, ordering and matching questions • Flashcards created from each lesson and scheduled by spaced repetition, so a card comes back shortly before you would forget it • A tutor inside every lesson that answers questions about what is on the page • Any part of a lesson read aloud when you would rather listen THREE WAYS TO LEARN • Course: structured lessons with quizzes and flashcards • How-to: one step-by-step guide to get something done • Practice: quiz sets that drill a topic, with no reading Need an exact list? Ask for "the 200 most common Italian words" or "all 118 elements" and the course teaches exactly that list, with a flashcard for every item. LEARN FROM YOUR OWN NOTES Import a PDF, Word, text or Markdown file, or take photos of your notes, handwriting included, and Coursor turns it into a course or a practice set. Choose how closely it follows: only your document, your document with extra explanation, or a full course on its subject. Lessons show the pages they come from. TALK IT THROUGH Have a spoken conversation with an AI coach. Practise a language you are learning with corrections that explain why, or talk about any topic in your own language with a coach who can be a curious friend, an expert or a debate partner. The microphone waits until you have finished speaking, and every conversation is saved so you can continue it later. PRACTICE WHAT NEEDS IT • Everything due today across all your courses, in one place • A weak-spot drill built from the questions and cards you keep missing • Knowledge checks: a short adaptive quiz on any topic, ending in a report of what you know, where the gaps are and what to study first SEE YOUR PROGRESS • Streaks, XP and your accuracy over time • The lessons and cards that need another look • A map of every concept you have learned and how the concepts connect MADE FOR MANY SUBJECTS Programming and mathematics, languages and pronunciation, music with chord charts and strumming patterns you can play back, professional skills, history, cooking, fitness and much more. YOUR LANGUAGE The app is available in English, Spanish, German, French, Italian, Portuguese, Russian, Arabic, Hindi, Indonesian and Chinese. Courses can be written in the language you choose, which does not have to be the language of your phone. YOURS TO KEEP • No account is needed. Your courses and progress are stored on your device. • Finished lessons, quizzes and flashcards can be studied offline. Creating new content needs an internet connection. • You can link an account to back up your library and restore it on a new device. • Light and dark themes, with several colour schemes. FREE, WITH OPTIONAL PLANS Coursor is free to use, with ads and daily limits. The optional Basic, Pro and Max plans remove all ads, raise the daily limits, read longer documents and use more capable AI.

You can cancel at any time in your store account settings. Courses are written by AI and can contain mistakes.
