Bloomling

Read full description

Bloomling is one warm little garden with three things inside: 11 logic puzzles made by the developer, a set of fully offline learning activities, and a walled-garden web area you control - only the pages you hand-pick can open, and everything else is gently blocked. HAND-MADE LOGIC PUZZLES (NO ADS, NO SIGN-IN) • Slide Puzzle, Ball Sort, Tower of Hanoi, Pipe Flow, Shape Bridge, Push the Boxes, Car Trip, Rolling King, Matchstick Math, Smart Squares, Marble Run • 50-120 levels each, from gentle to tricky, every one machine-verified to be solvable; Easy mode hints the next move and every move can be taken back • They train spatial reasoning, cause and effect, debugging and number sense - not reaction speed • One card per game, ready to play; no in-app purchases inside the games, no lucky draws, no timers BUILT-IN LEARNING ACTIVITIES (OFFLINE, NO NETWORK NEEDED) • Math Tutor: generates arithmetic questions and reads them aloud; answer by voice or by tapping. Voice is recognized entirely on-device - audio is never uploaded or stored • Story Machine: original bundled stories, narrated entirely with on-device speech • Read-Along: follow along sentence by sentence, in English and Chinese All three sit right at the top of the home screen the moment the app opens - no setup required. THE WALLED-GARDEN WEB AREA • Strict allow-list: only the exact URLs you add will open - even other pages on the same domain stay blocked (the one exception is the developer's own Puzzle Garden, where the child can move between games and tap Back) • No search box, no address bar, no outbound links - tapping anything outside your list just shows "Ask a grown-up for this page" • YouTube videos and playlists, and single Instagram posts: embedded in a locked, distraction-free view you can't navigate out of • Parent settings behind a gate: adding / editing / deleting / reordering sites requires solving a multiplication problem, or entering a 4-digit passcode you set • Adding a card is quick: paste a URL and see a green check (tap it to preview), a red cross or a duplicate warning right away; the card name can be filled in from the page title or typed by hand TOOLS FOR PARENTS • Groups: sort web cards into groups you name; each group is its own section on the home screen, and the order of the sections (including Today's Activities) can be rearranged by drag and drop • Per-weekday scheduling: choose which days of the week each card and activity appears • Usage review: see which pages were opened and for how long, by day, week or month - stored only on the device • Clear browsing data: wipe the cache and website data left by the web area in one tap • Cross-device setup: configure on another device, then send it over via AirDrop or the same Wi-Fi - no Apple account, no cloud • Export the list as a plain-text file (.md), edit and group it on a Mac with any editor, then import it back • Text editor: the whole web list as one page of text - copy it all as a backup, or paste a list and save • One app for iPhone and iPad YOU CAN RELAX • 100% ad-free • No third-party analytics, ad, or tracking SDKs (all Apple-native) • Collects no personal data; all settings and records stay only on your device • Every feature costs nothing and there is no paywall; the only purchase is an optional tip jar in the grown-ups area, and it unlocks nothing Offline learning activities, plus one little garden you trust - explore with peace of mind.

Sobo Math

Features
Read full description

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
