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
