For primary schools
    Live clock

    Learn to read the clock: playfully, digitally, with the whole class

    Zeitlernen turns one of the trickiest topics in grades 1–4 into a game: interactive clocks with movable hands, child-friendly theory, and a dashboard that shows you every child's progress.

    Made for everyday school life

    We built these features specifically for schools.

    Teacher dashboard

    Practice time, accuracy and the hardest clock times per class at a glance, with weekly trends and class comparison.

    Access codes instead of email

    Children sign in with the school code and their own codeword. No email account, no password chaos.

    Classes & team

    Create classes in seconds, assign children and invite fellow teachers to your school team.

    Every child in view

    Detailed view per child with results per game mode, plus automatic alerts when a child needs support.

    Excel import & export

    Import entire class lists via Excel and export reports for your records.

    Access sheets with QR codes

    Print-ready PDF access cards per class or child: scan the QR code and go.

    Swiss data protection

    Compliant with the Swiss FADP and the GDPR, operated in Switzerland. Children don't need a personal account.

    Four languages

    German, French, Italian and English, ideal for all of Switzerland's language regions.

    Runs anywhere in the browser

    No installation needed: works on tablets, laptops and the interactive whiteboard.

    Why this matters

    Reading the clock is abstract. Zeitlernen makes it tangible, guided by principles we stand behind.

    Differentiated practice

    Two difficulty levels in the same classroom, from a gentle start in 5-minute steps to the to-the-minute expert level.

    Encourage, never punish

    Friendly feedback, 1–3 stars per round and a personal best list. No child is ever punished.

    Honest learning time

    Only time from real practice rounds is counted. The dashboard numbers are honest: no idle time.

    Flexible in class

    As a 10-minute maths exercise, in learning stations, free work or substitute lessons. Self-explanatory, no preparation.
