How does it work?

Three steps, and times tables become part of the routine, no arguing needed.

  1. You set it up

    Install Debloquiz on your child's phone, create your parent code, pick the times tables to practise and when the quiz shows up.

  2. They answer

    When the phone is unlocked, or when a chosen app is opened, a multiplication appears. They have 5 seconds to answer.

  3. They learn

    Right answer: unlocked! Otherwise, the correct answer is shown in big letters, then a new question comes up.

Made for learning, set up by parents

5-second timer

Just enough time to think: a quick practice, not a chore.

The answer that teaches

Wrong or too slow? 7 × 8 = 56 is shown in big letters, then a new question comes up. Seeing it again and again makes it stick.

The tables you choose

Turn on the 1 to 10 times tables to match what your child is learning at school.

Unlock and/or chosen apps

The quiz at unlock, when opening the apps you pick (or all games), or both. Every time, or at most one question every 5 to 60 minutes.

Parent code

Settings are protected by a 4-digit code that only you know.

Emergency always available

The Emergency button stays visible on the quiz and opens the phone dialer: your child can always make a call.

100% offline

No account, no server, not even internet access: nothing leaves the phone.

No advertising, no trackers, no usage statistics.
