Math · grade 5
“Fairly hard CM2-level fraction word problems”
Léa ate 3/8 of a pizza and gave 1/4 of the whole pizza to her brother. What fraction is left?

Screen time that feels earned
★★★★★
“We type exactly what we want them to practice — fraction word problems, present progressive — and the quizzes match. No fighting over TikTok.”
★★★★★
“The curriculum topics are great, but the custom topics are why we stayed. Exam week = we add topics from school.”

“Finally an app that does one job well: learn first, scroll second. We use Family Link for web safety and Unlokid for the quiz gate.”
Curriculum sources
We use official programmes — and say so clearly
Quiz topics are not random trivia. Where a country publishes an official curriculum or standards API, we connect to it. Everywhere else we ship a hand-mapped catalog aligned to that country’s ministry guidelines — never a generic “AI guess” without saying so.

FAQ
Common questions
Will my kid figure out how to bypass it?
We use Android's Accessibility Service + Device Admin together — the kid would have to be very determined. You'll get email alerts if they try to uninstall or disable admin (when enabled below). We also block screenshots during quizzes.
How do you make sure the quiz content is appropriate and accurate?
Topics come from official curriculum data where it exists — France (data.education.gouv.fr / Eduscol), the UK (Oak National Academy · National Curriculum), the US (Common Core), and ministry-aligned catalogs for Israel, Germany, Spain, Italy and other countries. Answers are graded against a rubric, not just right/wrong. You can flag any question from the parent dashboard and it will not appear again.
Does it work offline?
Quizzes are pre-generated and cached on the device, so the kid can pass a quiz with intermittent connectivity. New quizzes need a brief online window.
iOS?
Not yet. Apple doesn't expose the APIs we need to lock other apps. Android only for now.
How is my child's data handled?
We keep quiz results and your child’s answers in your account so you can review progress in the dashboard. We do not sell personal data. Trusted providers (hosting, authentication, payments, email, and grading) process data only on our behalf. You can export or delete household data under Account → Privacy & data. See our privacy policy.
Can Unlokid block inappropriate or adult websites?
No — and that's deliberate. Web content filtering (adult, violence, gambling) is its own specialized field, and dedicated tools like Google Family Link, your broadband provider's filter, or a family DNS do it far better than any app whose real focus is something else. Safety filtering is too important to ship as a half-finished side feature. Unlokid is built to do one thing exceptionally well: turn screen time into learning by gating apps behind quizzes grounded in your child's curriculum. It layers perfectly on top of a proper content filter — use a true parental-control app to decide what to block on the web, and Unlokid for how your child earns their app time back. An app that claims to do both rarely does either well.
Can I create my own quiz topics?
Yes. On any subject, add a topic in your own words — for example "fairly hard fraction word problems at CM2 level" or "present progressive: give a verb, kid writes the -ing form". Unlokid generates fresh exercises that match. You can also create fully custom subjects with the guided wizard (text, links, or PDFs optional).
Can I set quiet hours when apps stay locked?
Yes. In your child's settings, enable quiet hours (e.g. no unlocks after 9 p.m. on school nights). During those windows, blocked apps stay gated even if your child still has minutes in their bank.
Every quiz is a small unlock. Every day is a bigger one.
Set it up tonight. Tomorrow morning, your kid earns their first unlock — and their first win.
