使用说明
记忆糖把要记住的做成记忆卡，把要做到的做成提醒卡。无需注册，数据默认只在这台 iPhone 上。
1. 这是什么
记忆糖是一款离线为主的 iPhone 应用，用来记住和做到：
- 刷到内容：在其它 App 里分享文字或网页链接到记忆糖，保存为提醒卡或记忆卡。
- 自己建记忆卡：正面写问题、背面写答案，按计划复习。
- 设提醒：到点提醒你去做；也可以做成可勾选的清单。
目前仅 iPhone、仅竖屏。无需注册账号，不接入广告或第三方统计分析。核心学习数据保存在本机；只有你主动使用内购、打开网页、分享、或开启 iCloud 时，才会用到网络或系统云服务。
2. 界面去哪找
底部四个入口：
- 今日打卡：今天该复习的记忆卡、该确认的提醒。
- 卡片管理：记忆卡与提醒卡列表。右上角「+」新建。
- 统计：打卡与记忆进度。
- 我的：设置、存储与备份、分享建卡、高级版、关于、反馈。
看到 ⓘ 就点一下，那是这一项的说明（例如练习怎么算一轮、一键打卡有几种方式）。局部说明看 ⓘ，整体用法看本页。
卡片详情里：铅笔改内容，Aa 调阅读密度，喇叭朗读正文（清单类提醒没有喇叭）。工具栏「+」可插入图片、拍摄、扫描纸页或提取文字。
3. 记忆卡（记住）
适合需要反复记的内容：单词、概念、要点。
- 正面通常是问题或提示，背面是答案或解释。
- 图片、录音、文档会出现在卡片上，复习时能看到、听到。
- 编辑正文时可用「+」扫描纸页（拍完可拖框矫正），或提取文字写入正文。
- 打卡时按记得程度选择，系统会安排下次复习时间。
练习 ≠ 今日打卡
- 今日打卡按复习计划走，打完会影响下次正式复习时间。
- 练习是额外加练。点「忘记」这张稍后还会再出现；练完可以选择是否开启抗遗忘，让系统开始安排正式复习。
单次练习最多 100 张。免费版练习筛选与排序较少，高级版可解锁更多方式。
4. 提醒卡（做到）
适合「到点去做」：回看一篇文章、吃药、收拾行李。
- 普通提醒：到点通知，可朗读正文。
- 清单类提醒：打卡时逐项勾选。可从模板快速创建，或新建空白清单。清单类没有朗读喇叭。
- 关闭提醒后，卡片只作记录，不主动通知，也不进入今日打卡。
- 需要长期记住时，可在详情里转为记忆卡；原提醒卡会归档，可在短时间内撤销。
5. 今日打卡
首页「今日打卡」汇总今天该处理的记忆卡和需打卡的提醒。
- 点开单张卡片可以提前打卡（未到点也可以）。
- 一键打卡会连续处理已到期、逾期的卡片。逾期指今日零点前就该完成、但尚未打卡的卡片。
- 可在系统桌面添加小组件，查看今日进度、连续天数和高亮条目标题。小组件数据仍在本机，不会因此上传到我们的服务器。
6. 分享建卡
在其它 App 打开系统分享，选择「记忆糖」，即可把内容保存为本机卡片。分享扩展只接收文字和网页链接，不接收图片、文件或其它类型。
抖音、B 站、知乎、微信公众号、Safari 等通常可直接分享。小红书、微博等若无法直接分享，可先复制链接，返回记忆糖（需在「我的 → 分享建卡」开启「自动识别分享链接」），确认后再建卡。剪贴板仅在本机识别，不会上传。
在「我的 → 分享建卡」可设置：
- 默认保存为提醒卡、记忆卡，或每次询问；
- 提醒卡的默认回看时间；
- 记忆卡的默认记忆方案、是否自动开启抗遗忘；
- 是否在卡片上显示来源。
不同 App 提供的标题、正文完整程度不一样，保存后可再编辑。分享进来的卡默认进入「来自分享」分类。
7. 数据与备份
卡片、复习记录、附件默认保存在设备本地，数据库加密存储。卸载应用通常会删除本机数据。
- 完整备份（ZIP）：在「我的 → 存储管理」导出，包含记忆卡、提醒卡、复习记录和附件。用于换机或迁移。备份可能含隐私内容，请自行妥善保存。
- 从 ZIP 恢复会覆盖当前设备上的全部数据。建议先再导出一份当前备份。
- 卡片包导出适合学习、打印或分享单类卡片；完整换机请用完整备份。
- iCloud 同步（可选）：在应用内开启后，把与完整备份相同的压缩包存入你 Apple ID 下的 iCloud 容器。恢复会覆盖本机全部数据。请先在系统设置登录 iCloud 并打开 iCloud 云盘。我们不会访问你的 iCloud 密码。
换新 iPhone 前，请先做完整备份或确认 iCloud 上已有备份。
8. 高级版
免费版大约可各创建 30 张记忆卡、30 张提醒卡（按占用计：删除会释放名额，归档不释放）。接近上限时会有提示。
高级版为 App 内一次性买断（非订阅），产品由 Apple 处理付款与退款，价格以 App Store 显示为准。同一 Apple ID 可在「我的 → 高级版」使用恢复购买。
高级版主要包括：不限卡片数量、自定义记忆方案、统计增强、PDF / 图片等导出、每张卡更多录音与文档附件、练习筛选与排序增强。
免费版每张卡约 1 段录音、1 个文档附件；图片附件不受此条限制。高级版权益以应用内实际提供为准。
9. 常见问题
通知没有响？
到 iPhone「设置 → 通知 → 记忆糖」打开允许通知。系统勿扰、专注模式、静音开关也会让你听不到声音。提醒卡若关闭了提醒，不会进入今日打卡，也不会通知。
分享列表里找不到记忆糖？
确认分享的是文字或网页链接。图片、文件不会出现本应用。部分 App 不提供系统分享，请复制链接后返回记忆糖识别。也可在系统分享面板下拉，把「记忆糖」添加到常用。
买了高级版却没解锁？
确认使用购买时的同一个 Apple ID，打开「我的 → 高级版 → 恢复购买」。付款与到账由 Apple 处理。
换手机后卡片没了？
数据默认只在原设备。请用完整备份 ZIP 恢复，或从已开启的 iCloud 下载恢复。恢复会覆盖新机上的现有数据。
扫描绿框时有时没有？
取景需要能看出近似矩形的纸页。太远、太近（四角出画）、侧得太厉害或纸与桌面对比弱时，框可能不出现。仍可拍摄，进入矫正页后再拖框。
练习算不算打卡？
不算。练习是加练；正式复习时间由今日打卡（以及你开启的抗遗忘）安排。

User guide
Turn what you want to remember into memory cards, and what you need to do into reminder cards. No account. Data stays on this iPhone by default.
1. What it is
MemoCandy is an offline-first iPhone app for remembering and following through:
- Save what you see: share text or a web URL from another app into MemoCandy as a reminder or memory card.
- Build memory cards: question on the front, answer on the back, reviewed on a schedule.
- Set reminders: get notified when it is time, or use a checklist you can tick off.
iPhone only, portrait only. No account, no ads, no third-party analytics SDKs. Study data stays on the device. Network or iCloud is used only when you start an In-App Purchase, open a web page, share, or turn on iCloud sync.
2. Where things are
Four tabs at the bottom:
- Today’s check-in: memory cards due for review and reminders to confirm today.
- Cards: memory and reminder lists. Tap “+” to create.
- Stats: check-in and memory progress.
- Me: settings, storage and backup, Share to Card, Premium, About, and feedback.
Tap ⓘ wherever you see it—that explains the item on that screen. Use this page for the whole workflow.
On a card: pencil to edit, Aa for reading density, speaker to read the body aloud (checklist reminders have no speaker). The “+” toolbar can insert a photo, capture, scan a page, or extract text.
3. Memory cards
Use these for material you want to keep: words, concepts, key points.
- Front is usually a prompt; back is the answer.
- Images, audio, and documents appear on the card during review.
- While editing, “+” can scan a page (then adjust the crop) or extract text into the body.
- When you check in, you rate how well you remembered; the next review time is scheduled for you.
Practice is not Today’s check-in
- Today’s check-in follows the review plan and changes the next official review time.
- Practice is extra drilling. Marking “Forgot” brings the card back later in the round. When you finish, you can enable Retention Mode so official reviews are scheduled.
At most 100 cards per practice session. Free practice has fewer filters and sort options; Premium unlocks more.
4. Reminder cards
Use these for “do this at this time”: revisit an article, take medicine, pack a bag.
- Regular reminders notify you and can be read aloud.
- Checklist reminders are for ticking items. Start from a template or a blank list. They have no speaker.
- If you turn the trigger off, the card is a record only: no notification and not in Today’s check-in.
- To keep it long term, convert to a memory card. The original reminder is archived; you can undo shortly after.
5. Today’s check-in
This tab lists memory cards and check-in reminders due today.
- Open a single card to check in early, even before the scheduled time.
- One-tap check-in walks through due and overdue cards. Overdue means it should have been done before today’s midnight and still is not.
- Optional home screen widgets show today’s progress, streak, and a highlight title. That summary stays on the device.
6. Share to Card
In another app, open the system share sheet and choose MemoCandy. The share extension accepts text and web URLs only—not images, files, or other types.
Apps such as Douyin, Bilibili, Zhihu, WeChat official accounts, and Safari usually share directly. If an app cannot share (for example Xiaohongshu or Weibo), copy the link, return to MemoCandy with “Auto-detect share links” on (Me → Share to Card), and confirm. Clipboard text is processed on-device only.
Under Me → Share to Card you can set the default card type, default reminder time, default memory plan, whether to auto-enable Retention Mode, and whether to show the source on the card.
Titles and body text from other apps vary. You can edit after saving. Shared cards go to the “From share” category by default.
7. Data and backup
Cards, review history, and attachments stay on the device by default (encrypted database). Uninstalling usually deletes local app data.
- Full backup (ZIP) from Me → Storage includes memory cards, reminders, review history, and attachments. Use this to switch phones. Keep the file private.
- Restore from ZIP replaces all data on this device. Export a current backup first.
- Card pack export is for study, print, or sharing a set of cards—not a full phone migration.
- Optional iCloud sync: stores the same kind of zip in your iCloud container. Restore overwrites everything on this device. Sign in to iCloud and enable iCloud Drive in system Settings. We never see your iCloud password.
Back up (or confirm an iCloud copy) before you switch iPhones.
8. Premium
The free plan allows about 30 memory cards and 30 reminder cards (by occupancy: deleting frees a slot, archiving does not). You will see a hint near the limit.
Premium is a one-time In-App Purchase (not a subscription). Apple handles payment and refunds; the price is what the App Store shows. Restore on the same Apple ID under Me → Premium.
Premium mainly unlocks unlimited cards, custom memory plans, richer stats, PDF/image export, more audio and document attachments per card, and extra practice filters and sorting.
Free cards allow about one audio clip and one document each; image attachments are not limited by that cap. Benefits are as shown in the app.
9. FAQ
No notification sound?
Allow notifications in iPhone Settings → Notifications → MemoCandy. Focus, Do Not Disturb, and the mute switch also silence alerts. A reminder with the trigger off will not notify and will not appear in Today’s check-in.
MemoCandy is missing from the share sheet?
Share text or a web URL. Images and files will not show this app. Some apps have no system share—copy the link and return to MemoCandy. You can also add MemoCandy to Favorites in the share sheet.
I bought Premium but it is not unlocked?
Use the same Apple ID and tap Restore Purchases under Me → Premium. Payment is handled by Apple.
Cards disappeared after a new phone?
Data lives on the old device by default. Restore from a full ZIP backup or from iCloud if you had sync on. Restore overwrites data already on the new phone.
The scan frame sometimes does not appear?
The camera looks for a page-like rectangle. Too far, too close (corners off-screen), a strong angle, or low contrast with the desk can hide the frame. You can still capture and adjust the crop on the next screen.
Does practice count as check-in?
No. Practice is extra. Official review times come from Today’s check-in and Retention Mode once you enable it.
