常见问题 FAQ
需要什么设备和系统?
iPhone 或 iPad,系统需要 iOS / iPadOS 26 或更新版本。界面和正文都有中文、英文两种语言,还可以中英对照阅读,在「设置 → 语言」里随时切换。
An iPhone or iPad running iOS / iPadOS 26 or later. The interface and the text are available in Chinese and English, and you can read both side by side; switch any time in Settings → Language.
换了设备或重装后,怎么恢复完整版?
打开「我的」→ 右上角「设置」→「完整版」→「恢复购买」,用当初购买时的 Apple 账户登录 App Store 即可,不会重复扣费。
Open Me → Settings → Full Version → Restore Purchases while signed in with the Apple Account you bought it with. You won't be charged again.
家人可以一起用吗?
可以,完整版支持「家人共享」。在系统设置里开启家人共享和「购买项目共享」后,家庭成员在自己的设备上就能使用;如果没有马上解锁,点一下「恢复购买」。
Yes — the Full Version supports Family Sharing. With Family Sharing and Purchase Sharing turned on, family members can use it on their own devices; if it doesn't unlock right away, tap Restore Purchases.
学习记录能在 iPhone 和 iPad 之间同步吗?
学习记录(已读、收藏、笔记、小测、复习卡)只保存在当前设备上,不会自动同步。换设备时,用「设置 → 数据 → 导出学习记录」生成一个 JSON 文件,在另一台设备上「导入学习记录」即可;导入是合并,不会删掉已有的记录。
Your learning record (read entries, bookmarks, notes, quizzes and review cards) stays on the device and doesn't sync automatically. To move it, use Settings → Data → Export learning record to save a JSON file, then Import learning record on the other device. Importing merges and never deletes what's already there.
朗读没有声音?
朗读走的是媒体音量:先按音量键调大音量,再看看是不是连着蓝牙耳机或音箱。想要更自然的声音,可以在「系统设置 → 辅助功能 → 朗读内容 → 声音」里下载中文和英文的增强语音。
Read-aloud uses media volume: turn the volume up and check for connected Bluetooth headphones or speakers. For more natural voices, download enhanced Chinese and English voices in Settings → Accessibility → Spoken Content → Voices.
怎么申请退款?
购买和付款都由 Apple 处理,开发者看不到订单,也无法直接退款。请到 reportaproblem.apple.com 登录你的 Apple 账户申请。
Purchases are handled by Apple; we can't see orders or issue refunds. Please request one at reportaproblem.apple.com.
书里的数字和年份可靠吗?
每个领域都附有一篇「资料来源与核实记录」,列出关键数字和年份的出处,在 App 的「全书 → 资料来源」里可以看到。发现错误欢迎告诉我们。
Each domain comes with a "sources and verification" record listing where key numbers and dates come from — see Book → Sources in the app. If you spot a mistake, please tell us.
发现错字或内容问题?
欢迎发邮件告诉我们,写上词条名(比如「蒸汽机」)或附一张截图;App 里「设置 → 支持 → 写邮件反馈」会自动带上版本号。
Please email us with the entry name (e.g. "Steam engine") or a screenshot. Settings → Support → Send feedback by email fills in the app version for you.
