Take everyday things apart,
piece by piece

Real 3D models you can rotate and open up. Tap a part and it explains itself — what it is and why it is built that way. Finish one and the next curiosity is already waiting.

Qiwu Deconstructor kid-side workbench
The kid-side workbench: resume, today's picks, daily challenge — with Xiaoqi alongside.

Screen time can also be hands-on time

Parents rarely ask "how many features does it have". They ask what their child is actually doing on the screen. We built those answers into the product, not into the marketing copy.

Fully offline after download

3D models, narrated audio and quizzes live on the iPad. Planes, trains and dead Wi-Fi are fine.

Eye-rest reminder at 15 minutes

A gentle break prompt appears after 15 minutes of continuous use. The interval is adjustable and can be turned off.

Time and content controls

Set a daily time limit, hide specific items, choose the grade level. When time is up, the kid side locks itself.

No ads, no social feed

No ads, external links, social features, location or top-up entries on the kid side. Locked content simply says "ask a parent".

Four steps from "what is that?" to "now I get it"

No manual needed. Within the first minute, a child has already taken the first part off.

  1. 1

    Pick an object

    Recommended by school grade: fewer parts and shorter text in grade 1; brakes and drivetrain in grade 6.

  2. 2

    Open it up

    Drag to rotate, pinch to zoom, step through the exploded view. Parts snap back into place for instant feedback.

  3. 3

    Listen, then answer one question

    Tap a part to hear its story from local audio, then try a question about how it works.

  4. 4

    Collect and grow

    Finished items join your collection, unlock achievements, and grow Xiaoqi from a hatchling into a star fox.

Four core capabilities

No bloated feature list — the effort goes into taking things apart properly.

3D deconstruction workbench

Every object is a part-based 3D model: rotate, zoom, step-by-step explode, highlight, reset. Parts are kept between 5 and 15 per grade so tapping stays accurate and smooth.

  • Step-by-step exploded view: easy to see, easier to remember
  • Tap any part — it explains itself
  • Triangle budget tuned per grade, so older iPads stay smooth
Splash screen and immersive view

One object, six grade editions

The same car exists as six separate grade editions: in early grades parts are merged and descriptions run 18–32 Chinese characters; by grade 6 the brake system is split out and text runs 50–85 characters, explaining principles rather than names.

Example shown for the car; the bicycle and the desk fan also ship with six grade editions.

Narrated parts and quizzes

Every part comes with local audio and a card. Correct answers earn growth points; wrong answers replay the explanation. Re-answering a question you already solved does not earn points twice.

  • 157 questions across 18 content packages
  • Quizzes configured per grade edition
  • Scoring happens on device, and syncs when online

Content that is already finished

3 objects × 6 grade editions = 18 content packages. Each edition is a separate product, recommended by the child's school grade.

Car content pack cover

Car

Where the power comes from, how it turns, why brake discs matter. Grade 6 splits the braking system out on its own.

More content keeps arriving: operators replace a model, register a new version, and the app prompts for the update — no reinstall needed.

Deconstructing is not the end — it is a loop

Open it, understand it, answer it, collect it, grow. Every step gives immediate feedback, so the child knows what just happened.

Onboarding and role selection
First launch takes three steps: language and region → parent phone login → choose who mainly uses this iPad.

Xiaoqi — a little mechanical fox that grows with your child

Xiaoqi is the companion on the kid side: it reacts when touched, offers hints when a child is stuck, and remembers what has been learned. Growth points come only from learning — petting earns nothing.

Lv1 Hatchling fox

Lv1 Hatchling

0–49 points

Joint covers are still missing and the chest core glows faintly. It needs you.

Lv2 Assembled fox

Lv2 Assembled

50–149 points

Ear modules and joint covers are fitted. It greets your child by name.

Lv3 Clever fox

Lv3 Clever

150–249 points

Fully assembled. It checks in, sets little quizzes and gives step hints.

Lv4 Starlight fox

Lv4 Starlight

250+ points

Starlight particles, learning recaps, next-object suggestions — and old looks to switch back to.

Parents can switch Xiaoqi off entirely; learning, quizzes, the field guide and growth points keep working.

The half that is built for parents

The kid side contains no prices, no ads and no social features. What parents need sits behind a verification gate.

Progress report

Sessions and learning time this week and this month, knowledge-point coverage, per-session quiz accuracy, and a data-generated comment. Exportable.

Content and time controls

Daily time limit, grade-based content levels, hidden items, mandatory eye-rest breaks. When time is up the kid side locks; the parent side stays open.

Account and child profiles

One parent account can hold several child profiles (at least 3). Collections, badges, progress and reports are stored per profile; membership and orders belong to the account.

Beyond the family

No real names, birthdays, schools, photos or locations are collected. No social or upload features. Anything paid passes a parent verification first, and account deletion has a 7-day cooling-off period.

Parent verification is the only payment gate. Entering the parent area, paying, submitting a print order, changing controls or deleting the account all require Face ID or the device passcode. On the kid side, locked content says only one thing: "ask a parent".

Start free, decide later

All six bicycle packs (grades 1–6) are free forever and fully explorable. When your child wants more, get the Explorer Pass — all three tiers include exactly the same content; they differ only in term and price.

Monthly Explorer

Standard ¥28 / monthFirst-term ¥8 / month

  • Free content + every member pack (car & fan, all grades)
  • Unlimited downloads, fully offline
Most popular

Quarterly Explorer

Standard ¥68 / quarterNo first-term discount

  • Identical benefits to the monthly and yearly tiers
  • Free content + every member pack (car & fan, all grades)
  • Unlimited downloads, fully offline

Yearly Star Explorer

Standard ¥228 / yearNo first-term discount

  • Identical benefits, longest term, lowest monthly cost
  • Free content + every member pack (car & fan, all grades)
  • Unlimited downloads, fully offline

All three tiers are identical: while the pass is active you can open every paid pack — there are no content tiers and no single-item purchases, so you never pay twice for the same item.

First-term offer: the monthly ¥8 first-term price is available on the China mainland storefront only and is set by the App Store for the signed-in account; quarterly and yearly passes have no first-term discount. The price shown inside the app is authoritative.

Renewals and refunds: subscriptions go through Apple In-App Purchase; auto-renewal can be turned off any time in system Subscription settings. The purchase page offers "Restore Purchases". Prices shown in the app are authoritative; regional prices follow App Store price tiers.

None of these prices ever appear on the kid side — money only exists in the parent area.

Frequently asked

What age is it for?

Grades 1–6 (roughly ages 6–12). Content ships as separate grade editions: fewer parts, shorter text and slower narration early on; finer detail and principles in later grades. The grade can be changed by a parent at any time.

Does it need an internet connection?

After a content package is downloaded it works fully offline — 3D models, narration and quizzes are stored on the iPad. Only sign-in, store listings, downloads and progress sync need a network.

Will paid prompts interrupt play?

No. The kid side shows no prices, ads or marketing pop-ups; locked content just shows a lock and "ask a parent". Every purchase happens in the parent area behind parent verification.

Can several children share one iPad?

One parent account supports at least 3 child profiles. Collections, badges, progress and reports are kept per profile; membership and orders are shared across the account.

How is screen time managed?

A gentle break prompt appears after 15 minutes of continuous use (adjustable), and parents can set a daily limit that locks the kid side when reached. Learning results are never lost.

Which devices are supported?

iPad, best in landscape. iPhone and Android are not on the roadmap for this version.

The first beta slots are opening

The app is in final acceptance on iPad. Leave your contact details and we will send installation instructions when the beta opens.

Beta contacts are used only for testing and feedback — never for marketing.
