Odysseo : révision scolaire

Odysseo brings together the entire school curriculum, from first grade to twelfth grade, in a single app: 828 animated chapters narrated aloud, across 14 subjects, aligned with the national education curriculum.

Your child understands instead of memorizing—and you can finally see where they stand.

WHAT YOUR CHILD GAINS

They understand.
Each chapter is a short educational cartoon: diagrams are built in sync with the explanation, read aloud. A concept that has been a stumbling block for weeks becomes clear in minutes.

They retain.
Odysseo identifies what has been mastered and what is still a challenge, then revisits each concept at the right time—this is spaced repetition. Your child reviews what they need, not what they already know.

They review without even thinking about it.
More than 28,000 questions where each answer, right or wrong, explains the concept. Progress is made even without having studied the lesson beforehand.

WHAT YOU GAIN

A clear dashboard: attendance, time spent, strengths, and areas for improvement, subject by subject. Enough to support without monitoring.

Multiple children on the same device, each with their own class and progress.

No ads, no trackers, no account creation. Progress data remains on the device.

IT WORKS OFFLINE

Lessons, narration, and quizzes are downloaded. On the train, in the car, on vacation, or in an area with no internet access, the app works completely offline.

ALL SUBJECTS, ALL LEVELS

Primary (Grades 1-5): French, Math, Science, Technology, History, and English.

Middle School (Grades 6-9): French, Mathematics, Physics and Chemistry, Life and Earth Sciences, Technology, History and Geography, English, Spanish, German. Integrated preparation for the Brevet exam.

High School (Grades 10-12): French, Mathematics, Physics and Chemistry, Life and Earth Sciences, Economics and Social Sciences, Science, Philosophy, English, Spanish, German. Integrated preparation for the Baccalaureate exam.

HOW FAMILIES USE IT

In the evening, ten minutes on the day's lesson, when something wasn't understood in class.
Before a test: the chapter, then the quizzes, then the review sheet.
During the holidays: a few chapters per week to keep up, without a workbook.

At the end of the year: preparation for the Brevet or Baccalaureate exams, chapter by chapter.

Odysseo is not a private tutor or a remote homework service: it's an independent revision tool that your child opens on their own and that you can access whenever you want.

WHY NO ACCOUNT OR ADS

A school app is designed for children. Therefore, we've chosen the opposite approach: no registration, no email address required, no banners, no audience measurement, no profiling. Nothing to accept before starting, nothing to decline afterward.

TRY IT FREE

For 7 days, the entire app is open: no payment, no commitment, no credit card required. After that, the first chapter of each subject remains free, at every level.
