三件事
不是功能清单，是三个承诺
ContextEcho 只做好这几件事，其余的刻意不做。
看见自己
连续天数、累计时长、节目排行、平台分布、学习热力图——一面属于自己的收听镜子，打开一眼就懂。
不打扰的陪伴
Smart Speed 跳静默、Voice Boost 提人声；锁屏、CarPlay、控制中心、耳机操作就绪。不推送、不打卡。
真实截图
App Store 上的 8 张截图，就是全部功能
没有渲染图，没有「即将推出」。点开任意一张放大看。
2 分钟介绍
先看视频，再决定要不要装
发布在 X 上的介绍视频，5,000+ 次观看。
一个入口
播客、B 站、YouTube，
不用在三个 App 之间切
播客 RSS、小宇宙链接、B 站视频与合集、YouTube 视频与播放列表——粘贴链接就能导入， 全部汇入同一个时间线。网页文章也支持。
- 合集顺序播放：B 站合集、播客系列按顺序听完，播到末尾即停，不打扰。
- 按节目折叠：更新多的节目自动折叠成摘要，首页不被刷屏。
- 播客可下载：单集离线收听，通勤地铁里也稳。
学习统计
听过的每一个小时，
都看得见
这不是附属功能，是 ContextEcho 存在的理由：每天打开，知道自己没有让时间白白溜走。
- 今日时长 + 连续天数：点开看当日明细，断没断一眼知道。
- 学习热力图 + 趋势图：13 周热力图、按日趋势，习惯长什么样自己清楚。
- 节目排行 + 平台分布：最常听谁、播客和 B 站各占多少，一目了然。
- 收藏单集：给好单集加星，学习统计里随时回访。
数据全部本地存储，可随时导出 JSON，也可以随时删除。
听感
Smart Speed 跳静默，
Voice Boost 提人声
Smart Speed 自动跳过语句之间的静默、保持音调自然，省下来的时间计入你的学习统计； Voice Boost 让人声更清晰，长听不累。
- 锁屏 / CarPlay / 控制中心 / 耳机：跑步、通勤、开车、睡前都顺手。
- ±15 秒快进快退：播客、B 站、YouTube 全都支持，全屏也在。
- 倍速记忆：每个节目记住自己的倍速偏好。
偶尔用得上
想留住一句话，
不必掏手机
耳机双击、锁屏一下、Siri 一句、控制中心一按——当前播放位置立刻钉在时间轴上， 也可以顺手写一句想法。事后在单集详情里找回。
这不是主流程：用得上就用，不用也不会被催。没有每日提醒，没有小红点。
诚实沟通
说清楚做什么、不做什么
买之前先看这里——你的时间和 $5.99 都很贵。
可能很适合你
- 每天有 30 分钟到 2 小时听知识类播客或 B 站 / YouTube 学习内容。
- 想要一面统一的学习统计镜子，而不是分散在小宇宙、B 站、YouTube 三处。
- 「打开就续听 + 看见自己的数据」对你是真实的动力。
- 在意隐私：想要无账号、本地存储、不被分析的 App。
暂时不是这个
- 不做节目发现、社交、评分榜单、推荐流。
- 不做知识库、自动总结、AI 生成内容。
- 不是全文翻译工具，也不是英语学习 App。
- 没有云同步和账号系统（本地优先是刻意选择）。
常见问题
买之前想知道的
ContextEcho 是什么？
一款 iOS 学习统计播放器：把中英文播客（RSS / 小宇宙）、B 站视频与合集、YouTube 播放列表放进同一个时间线续听，并在「学习统计」里看见连续天数、累计时长、节目排行与学习热力图。
收费吗？有订阅或内购吗？
买断制付费 App（美区 $5.99，其他地区以 App Store 当地定价为准）。一次购买、无订阅、无内购，支持家人共享（最多 6 人）。
支持哪些内容来源？
播客 RSS 与小宇宙链接、B 站视频与合集、YouTube 视频与播放列表，以及网页文章。粘贴链接即可导入，所有来源共用一个时间线和一个学习统计页。
会收集我的数据吗？
不会。App Store 隐私标签为「未收集数据」：无账号系统、无分析 SDK。收听记录、标注和笔记全部存在本机，不上传云端，可导出 JSON 也可随时删除。
可以离线使用吗？
可以。播客单集可下载离线收听；原文、时间戳标注和笔记都可以离线阅读与编辑。联网只在你主动刷新订阅或在线播放时发生。
和普通播客 App 有什么区别？
它不做节目发现、社交、评分榜单和推荐流，专注两件事：打开就稳稳续听；回来能看见自己听了多少。如果你要的是「发现新节目」，它可能不适合你；如果你要的是「把已订阅的听完并看见积累」，它正合适。
什么是 Smart Speed 和 Voice Boost？
Smart Speed 自动跳过语句之间的静默并保持音调自然，省下的时间计入学习统计；Voice Boost 提升人声清晰度，长时间收听更轻松。两者都可以随时开关。
支持哪些设备和语言？
需要 iPhone（iOS 17 及以上），Apple Silicon Mac 也可运行。界面支持简体中文和英文；锁屏、CarPlay、控制中心与耳机控制均已就绪。
现在就能装上，今天开始积累
一次买断，无订阅无内购。装上之后，第一件事就是把你常听的节目粘贴进来。

Three things
Not a feature dump — three promises
ContextEcho does a few things well, and deliberately skips the rest.
Play reliably, every day
Open the app and continue from your last position. The Mini Player follows you across pages — one tap and you're back.
See yourself
Streak, total hours, show rankings, platform split, and a habit heatmap — a mirror of how you actually listen.
Quiet company
Smart Speed skips silence, Voice Boost lifts voices; lock screen, CarPlay, Control Center and earbuds ready. No nags.
Real screenshots
The 8 App Store screenshots are the whole app
No mockups, no "coming soon". Tap any screen to zoom in.
2-min intro
Watch the video before you buy
The intro video posted on X — 5,000+ views.
One inbox
Podcasts, Bilibili & YouTube —
no more app switching
Podcast RSS, Xiaoyuzhou links, Bilibili videos and collections, YouTube videos and playlists — paste a link to import. Everything lands in one timeline. Web articles work too.
- Collections play in order: listen through a Bilibili collection or podcast series; playback stops at the end — no auto-queue.
- Folded by show: busy shows collapse into a digest so your home stays calm.
- Podcast downloads: take episodes offline for the subway.
Learning Stats
Every hour you listened,
visible
Not a side feature — it's why ContextEcho exists: open it once a day and know you're not letting time slip away.
- Today's time + streak: tap through for the day's detail.
- Habit heatmap + trend: 13 weeks of heatmap and a by-day trend chart.
- Show rankings + platform split: who you listen to most, and where.
- Starred episodes: star the great ones, revisit them from Learning Stats.
All data stays on device. Export as JSON, or delete it — anytime.
Sound
Smart Speed skips silence,
Voice Boost lifts voices
Smart Speed trims the gaps between sentences while keeping pitch natural — the time saved counts toward your stats. Voice Boost makes long listening easier on the ears.
- Lock screen / CarPlay / Control Center / earbuds: ready for runs, commutes, driving, bedtime.
- ±15s seek: on podcasts, Bilibili and YouTube — fullscreen included.
- Per-show speed memory: each show remembers its own speed.
When you need it
Keep a line worth keeping —
without reaching for your phone
Double-tap your earbuds, tap the lock screen, ask Siri, or hit Control Center — the current second gets pinned on the timeline, optionally with a quick note. Find it later in the episode detail.
Not the main loop: use it when you want. No daily reminders, no badges.
Honest scope
What it is — and isn't
Read this before you buy. Your time and $5.99 both matter.
Probably for you
- You spend 30 minutes to 2 hours a day on knowledge podcasts or Bilibili / YouTube learning content.
- You want one unified stats mirror instead of scattered histories in three apps.
- "Open, resume, see my numbers" is a real motivator for you.
- You care about privacy: no account, local storage, no analytics.
Not this, not now
- No show discovery, social features, charts, or recommendation feed.
- No knowledge base, auto summaries, or AI-generated content.
- Not a translation tool or an English-learning app.
- No cloud sync or accounts — local-first is a deliberate choice.
FAQ
Before you buy
What is ContextEcho?
A learning-stats player for iOS: Chinese & English podcasts (RSS / Xiaoyuzhou), Bilibili videos and collections, and YouTube playlists in one timeline — with streaks, hours, show rankings, and a habit heatmap in Learning Stats.
How much does it cost? Any subscription?
It's a one-time purchase ($5.99 US; local pricing varies by storefront). No subscription, no in-app purchases. Family Sharing supported for up to six members.
Which sources are supported?
Podcast RSS and Xiaoyuzhou links, Bilibili videos and collections, YouTube videos and playlists, plus web articles. Paste a link to import; everything shares one timeline and one stats tab.
Does it collect my data?
No. The App Store privacy label is "Data Not Collected": no account, no analytics SDKs. Listening history, markers and notes stay on your device; export as JSON or delete anytime.
Does it work offline?
Yes. Podcast episodes can be downloaded; text, markers and notes are readable and editable offline. Network requests happen only when you refresh subscriptions or stream.
How is it different from a regular podcast app?
No discovery, social, charts or feeds. It focuses on two things: play reliably when you open it, and show you what you've been listening to when you return. If you want to discover shows, it's not for you; if you want to finish what you subscribed to and see the hours add up, it is.
What are Smart Speed and Voice Boost?
Smart Speed skips the silences between sentences while keeping pitch natural — saved time counts toward your stats. Voice Boost lifts voice clarity for easier long listening. Both can be toggled anytime.
Devices and languages?
iPhone with iOS 17 or later (runs on Apple Silicon Macs too). The UI is available in English and Simplified Chinese; lock screen, CarPlay, Control Center and headphone controls are all supported.
Install it now. Start counting today.
Buy once — no subscription, no in-app purchases. First thing after install: paste in the shows you already listen to.
