一把尺子

不是功能更多的播客 App

比较尺度不是节目发现、榜单或推荐流「多一点」,而是:打开就能续听你已经在意的内容,并看见自己听了多少。 不做发现,专做听完与看见积累。

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。

01 · PLAY

每天稳稳地播

打开 App 就接着上次的位置;Mini Player 全程跟随,一点即回。跑步、通勤、家务、睡前,天天可靠。

02 · MIRROR

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。

03 · ALONG

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。

上架前:连续 72 天,一年累计 157 小时 上架后:连续 38 天,近 30 天 77 小时

活过的证明 · 学习统计

听过的每一个小时,
都看得见

上架前我自己先用了 72 天;上架后又连续 38 天。 左边是上架前的一年累计(157 小时),右边是上架后的近况——这是我的真实学习统计,不是渲染图。

  • 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。

一个入口

播客、B 站、YouTube,
不用在三个 App 之间切

  • 批量导入与合集:一次粘贴多条链接,导入后直接整理成一本合集。
  • 播客可下载:可限制仅 Wi-Fi 下载并管理占用空间,通勤地铁里也稳。
统一搜索:播客、Bilibili、YouTube

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。

  • ±15 秒快进快退:播客、B 站、YouTube 全都支持,全屏也在。

听感设置:Smart Speed 与 Voice Boost
锁屏上的「已记下」提示 逐字稿里留下这一刻

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。

最近更新 · v1.2.1–1.2.4

更快找到想听的,也更容易把好内容带走

当前 App Store 版本已经包含这些更新——决定装之后再看也完全来得及。

FOLLOWING · INBOX

首页分工更清楚

给常听的节目加星后,「关注」集中展示近期更新和没听完的单集;「收件箱」保留全部内容。两个分段都能随时搜索整个内容库。

BATCH · COLLECTIONS

一次导入,多条整理

粘贴多条链接即可批量解析,并直接创建合集;新用户也可以从内置精选开始,确认后才会联网订阅。

LISTEN · EXPORT

收听更稳,记录可带走

播客支持 0.5–3.0x 精细倍速、仅 Wi-Fi 下载与缓存管理;单集想法和逐字稿可导出为 Markdown,方便放进自己的笔记。

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 ¥38 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:中国区 ¥38,美区 $5.99(其他地区以 App Store 当地定价为准)。大约一杯星巴克的钱。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

¥38 一次买断,大约一杯星巴克的钱——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。

A different yardstick

Not another podcast app with more features

The comparison isn't discovery, charts, or recommendation feeds — it's whether you can open the app, resume what you already care about, and see how much you've actually listened. No discovery. Finish what you subscribed to, and see the hours add up.

Three things

Not a feature dump — three promises

ContextEcho does a few things well, and deliberately skips the rest.

01 · PLAY

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.

02 · MIRROR

See yourself

Streak, total hours, show rankings, platform split, and a habit heatmap — a mirror of how you actually listen.

03 · ALONG

Quiet company

Smart Speed skips silence, Voice Boost lifts voices; lock screen, CarPlay, Control Center and earbuds ready. No nags.

Before launch: 72-day streak, 157 hours in a year After launch: 38-day streak, 77 hours in 30 days

Lived proof · Learning Stats

Every hour you listened,
visible

I used it myself for 72 days before it shipped — and another 38 days after. Left is the pre-launch year (157 hours); right is life after listing. My real Learning Stats, not a mockup.

  • 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.
  • 0.5–3.0x fine speed: tap through common presets or adjust the current episode in 0.1 steps.

Lock screen capture confirmation Capture this moment from the transcript

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.

Recent updates · v1.2.1–1.2.4

Find what you want faster — and take the good parts with you

Included in the current App Store release — fine to read after you've decided to install.

FOLLOWING · INBOX

A clearer Home

Star the shows you care about: Following gathers recent updates and unfinished episodes, while Inbox keeps everything. Search your whole library from either segment.

BATCH · COLLECTIONS

Import many, organize once

Paste multiple links for batch parsing and turn them straight into a collection. New listeners can start from curated picks — nothing connects until you confirm.

LISTEN · EXPORT

Steadier listening, portable notes

Podcasts gain 0.5–3.0x fine speed control, Wi-Fi-only downloads, and cache management. Export episode thoughts and transcripts as Markdown for your own notes.

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?

One-time purchase: $5.99 US (about the price of a coffee); ¥38 in China. 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.

$5.99 one-time — about the price of a coffee. No subscription, no in-app purchases. First thing after install: paste in the shows you already listen to.
