AI4Kids
A native iPhone & iPad activity app where kids play, learn, and create — seven offline activities plus parent-unlocked AI Workshops powered by DeepSeek.
⬇️ Download on the App Store
Inspired by the AI Kids Academy programme by Tertiary Infotech.
Version 1.6 adds four AI Workshops behind a grown-up login and restyles the app in
the website's warm cream, purple, teal and sunny-yellow palette (Fraunces / Nunito).
All seven play activities continue to work offline.
✨ Overview
AI4Kids is a bright, friendly universal app (iPhone + iPad) for young learners (ages 4–16), with layouts that adapt to each screen size. It bundles seven self-contained learning activities that run entirely on-device (no internet, no accounts, no ads and no data collection), plus four optional AI Workshops that a parent unlocks with a PIN and their own DeepSeek API key.
🎮 The Seven Activities
| Activity | Ages | What kids do |
|---|
| 🔤 | Phonics Quest | 4–6 | Seven sound worlds of phonics mini-games with on-device phoneme audio. |
| 📖 | Story Builder | 7–9 | Pick a hero, place, object and mood; the app weaves a twice-branching story. |
| 🧩 | Code Puzzles | 10–12 | Sequence arrows and Scratch-style repeat loops to walk a robot to the goal. |
| 🚪 | Escape Room | 8+ | Five walk-around puzzle rooms full of clues, keys and locked doors. |
| 🎨 | Art Studio | All | Compose an on-device picture, then solve it as a tap-to-place jigsaw. |
| 💬 | Talking Buddy | All | A rule-based offline chat pal that talks back with speech synthesis. |
| 🕹 | Brain Arcade | All | Eight quick solo card games — matching, memory, sums and sorting fun. |
Every win earns ⭐️ stars, tracked locally and celebrated with confetti.
🤖 AI Workshops (parent-unlocked)
| Workshop | Ages | What kids do with "Sunny" |
|---|
| Storybook Studio | 7–12 | Pick a hero, place and twist; choose a story spark; co-write a Merlion adventure. |
| Mini Maker Studio | 7–12 | Plan a poster (title, slogan, pictures to draw) and a 4-panel mini comic. |
| Maths Detectives | 8–12 | Solve Singapore-themed maths mysteries, one hint at a time, at P1–P6 levels. |
| Science Explorers | 8–12 | Ask "why/how" questions, then try a safe at-home mini experiment. |
- Grown-up login. On first use a parent creates a 4–6 digit PIN and pastes their own
DeepSeek API key (checked live), then consents.
Later visits need only the PIN. Sessions lock when the app is backgrounded, after 30
minutes, or on "Lock now"; five wrong PINs trigger a 60-second cooldown.
- Secrets stay on the device. The PIN (salted SHA-256) and the key are stored in the
Keychain (
ThisDeviceOnly). The app ships no API key and runs no server.
- Kid-safety. A client-side filter blocks emails, phone and NRIC numbers and addresses
before sending. System prompts keep replies short, kind and age-appropriate, and every
screen reminds kids that AI can make mistakes.
🔒 Privacy
AI4Kids is designed to be kid-safe by construction:
- The seven play activities are fully offline and collect nothing.
- AI Workshops are off by default. When a parent turns them on, only the text a child
types in a workshop is sent to DeepSeek (
api.deepseek.com), billed to the parent's own key.
Nothing is stored off-device by us, and nothing is linked to identity.
- No accounts, no ads, no analytics, no in-app purchases.
- Progress (just a star tally) lives on-device in
UserDefaults.
- A built-in Parents' Corner explains the no-data stance and can reset progress —
guarded by a parental gate (a grown-ups-only math challenge, as in the Android app).
- App Store privacy label: Other User Content, not linked to identity, not used for
tracking, for App Functionality only.
PrivacyInfo.xcprivacy declares the same. Because
of this third-party AI data flow, v1.6 is listed under Education, not the Kids Category.
🏗 Architecture
SwiftUI Views (one per activity) ─> ProgressStore (@Observable, UserDefaults)
RootView (home grid) ─> fullScreenCover ─> activity views
App/ — entry point, RootView (home grid + Parents' Corner), Theme (kid palette + helpers)Models/Activity.swift — the seven activities and their card metadataModels/AIWorkshop.swift, Models/KidSafety.swift — workshop prompts and the pre-send safety filterServices/ParentAuth.swift, Services/Keychain.swift — parent PIN session and Keychain storageServices/DeepSeekClient.swift — the only networking code in the appServices/ProgressStore.swift — the single @Observable injected into the environment (the only place that persists)Components/SharedUI.swift — KidButton, StarBadge, CelebrationView, CloseButtonViews/ — one self-contained SwiftUI view per activity
Built with Swift 6 complete strict concurrency, @MainActor isolation throughout, and the Observation framework (not Combine). No third-party dependencies.
