WordScene vs iRamon － 开小车学编程

WordScene is a vocabulary learning app that turns the world around you into word cards. Snap an object, scan English text, import a photo, or say a word aloud to create cards you can save, review, quiz, and practice. Key features: - Snap words: full camera preview with object recognition, OCR, and photo import. - Word cards: word, phonetic spelling, part of speech, meaning, example sentence, translation, category, and tags. - Offline dictionary: built-in commercially usable dictionary data with common exam tags. - Daily review: SM-2 spaced repetition schedules the right cards for today. - Practice and quizzes: flip-card practice and local quiz types generated from your own word library. - Pronunciation practice: speech recognition based scoring for speaking practice. - Learning stats: streaks, mastered words, daily progress, and activity heatmaps. - System integration: widgets, Live Activities, Siri Shortcuts, local reminders, and TTS. WordScene's dictionaries, review, and on-device recognition work without a network connection. AI routing defaults to Automatic, but no data is sent in the background. Before every Snap or voice lookup request, the app explains what will be sent, who receives it, and why, then asks permission for that request. Automatic mode uses only Alibaba Cloud in mainland China and only Gemini elsewhere, with no cross-region fallback. Model credentials stay on the server and are not shipped in the app. The free tier provides Snap, OCR, voice lookup, offline dictionaries, review, quizzes, stats, and sharing without an account, with ads only on static library, stats, and settings surfaces. Monthly or Annual WordScene Pro unlocks smart focus decks, personalized plans, advanced insights, and removes ads. Lifetime Remove Ads is a one-time purchase that removes ads only. All digital entitlements use Apple In-App Purchase; there is no external purchase unlock.

这是一位爸爸送给儿子 Ramon 的生日礼物——一款把「编程的本质」做成游戏的 App。 孩子拖动积木指挥小车前进、转弯、吃金币；而每一块积木的背后，都是一行真正的 Lisp 代码，实时显示在屏幕下方。玩着玩着，孩子会发现：程序就是列表，列表可以嵌套，重复的动作可以起名字——然后有一天，他会亲手拼出自己的第一个括号表达式。 【主线：150关，十六章】 • 从「前进一步」开始：命令、顺序、重复、条件、循环 • 改编自经典《The Little Schemer》与《The Seasoned Schemer》：car、cdr、cons、递归、letrec、letcc……每一关都是书里的一课 • λ 工坊：把自己的程序打包成新积木（这就是 define），还能带参数、勾选递归 • 画笔章节：让轨迹变成图形，用递归画出分形 【训练场：八种玩法】 • 你当解释器 —— 先猜小车停在哪，再运行验证 • 问答茶歇 —— 大象教练的苏格拉底式问答，原书风味 • 故事工坊 —— 写「匹配-替换」规则，让故事自己走下去 • 魔法改写间 —— 发明新咒语，规则翻译给解释器（宏的第一课） • 聪明队友 —— 给机器人阿括目标，它自己想出计划 • 音乐盒 —— 旋律是列表，移调倒放就是数据变换 • 魔法画板 —— 拨参数画雪花与分形树，一键分享 • 黑客终端 —— 密室逃脱：亲手拼出 S-表达式开门救机器人 【收集与奖励】 207 辆小车等你解锁：JDM 街车、超跑、拉力、电动……还有只属于 Schemer 的隐藏车队。找齐彩蛋关，神秘车库里的电影科技座驾在等你。 【家长放心】 • 主线离线、海报按需下载，iCloud跨设备同步。 • 无广告、无内购、无社交功能 • 全部音效由代码合成，可一键静音 • 适合 6–12 岁，也适合任何想理解「程序为什么是列表」的大人 愿每个孩子都能遇见括号里的魔法。生日快乐，Ramon。
