Sobo Math

HK P4–P6 Math · Cantonese

Free · In-App Purchases · Designed for iPad. Not verified for macOS.

Your child may not be “bad at maths”—they may be using an app built for another curriculum. Sobo Math follows Hong Kong EDB Key Stage 2 (Primary 4–6): 41 units and 231 stages on one clear map. This is an independent app, not an official EDB product. Why families choose us • Mapped to HK P4–P6: number, measures, shape, data, algebra • 4,900+ questions with interactive visuals and step-by-step help (not every item has a diagram) • Traditional Chinese, Simplified Chinese, and English text; Cantonese, Mandarin, and English read-aloud—script and voice can be set separately • Daily path, quests, and streaks • Sobo grows with practice XP (no pay-to-skip evolution) • Parent report: all weak-skill names free; one-tap practice on the first gap • Offline lessons, no third-party ads, no account Free includes every unit in order (daily energy limits how fast; later units unlock after earlier ones). Mock exam: 10 questions untimed. PRO: skip-ahead, unlimited energy, timed mocks (20–35 questions by year), unlimited adaptive review, full parent shortcuts and export. Practice papers here are school-style drills, not official TSA or school exam papers. Start free. Yearly plan may include a trial for eligible new subscribers (App Store terms). Subscriptions: Monthly HK$78 / Yearly HK$588 (~HK$49/mo). Auto-renews; cancel in Apple ID settings. Privacy: https://sisiyeung1126-max.github.io/math-games-ios/privacy.html
