Read full descriptionHide full description
Chinese, English and Maths for Hong Kong primary school (P1–P6), taught like a tutorial centre: revise, practise, check, all at home. Plus Hong Kong stroke order and mock dictation. ■ Taught like a tutorial centre • Daily timetable: one Chinese, one English and one Maths lesson a day (about 15 minutes), chosen from your child's weak spots. • Revise first, then practise: every lesson has key points, worked examples, common mistakes and diagrams, then 10 questions with explanations. • Report card: grades and weak spots for all three subjects, at a glance. ■ Chinese • Stroke practice in Hong Kong stroke order, with instant feedback on a wrong stroke. • This week's dictation (默書): AI import: photograph the school's list and AI turns it into a word list (the photo is sent for recognition only after a parent agrees, and we do not store it; on iPhone and iPad you can instead read the words on the device, where nothing is uploaded). Practise writing, run a mock dictation (the app reads in Cantonese, your child writes on paper), or print worksheets. • 10 language-skill lessons: measure words, antonyms, synonyms, punctuation, linking words, word classes, idioms (with pictures), 的/得/地, figures of speech. • Reading comprehension: 12 original passages for P1–P6, with explanations and read-aloud. ■ English • 815 words, spelling, sentence building and tests. • 19 grammar lessons (a/an, plurals, prepositions, tenses, comparatives, conjunctions, questions and more), each answer explained. • English dictation: the app reads the word, your child writes it, then checks the spelling. • Reading: 12 original passages for P1–P6, with explanations. • Free Chinese–English dictionary: search Chinese for Jyutping, stroke order and meanings; search English to find Chinese words. AI word explanations and homework scan in Cantonese (monthly AI allowance, extra packs available). ■ Maths • 72 topics from P1 to P6: operations, place value, factors, fractions, decimals, percentages, time, units, shapes, angles, perimeter, area, volume, circles, speed, simple equations and more. • Word problems for every grade; pictograms and bar, line and pie charts. • 3D maths lab: build a cuboid layer by layer, fold a cube net; drag to rotate. • 20-question test, mental maths challenge, A4 worksheets with answers. ■ For parents • Several children with separate progress; printable A4 report card. • All records stay on the device. AI import is optional: a photo is sent for recognition only after a parent agrees, and we do not store it. No ads, no tracking, no third-party analytics. • A parent gate before purchases and external links; Large Text mode. ■ Free and subscription The free version includes the daily timetable (Primary 1 content, not counted against free sessions), the first 100 Primary 1 characters, Primary 1 English and Maths, the first 6 characters of each week's dictation list, one mock dictation a week, 3 worksheets, the dictionary, games and records, plus 3 other practice sessions a day. Subscribing unlocks everything from P1 to P6 plus advanced, unlimited dictation lists and mock dictations, and unlimited practice and worksheets. The yearly plan includes a 7-day free trial (you subscribe first; you are charged only when the trial ends, and not at all if you cancel in Apple ID settings at least 24 hours before it ends).

Verdict
The clearest difference is in-app purchases: 開班啦 at none against LKS 小學默書補習社's 3. 開班啦 also leads on iOS requirement (9 vs 15.0). On price, update cadence, ads and device support there is nothing between them.
