# 关于 Bifrost

Bifrost 是北京燕婉科技有限公司推出的全球社交 App。我们相信，一个目标有人同行，会更容易坚持下来。

## Bifrost 是什么

Bifrost（App Store 名称 Bifrost: Global social）是一款全球社交 App。它按近期目标为用户匹配真实的同行者：双方在 12 小时内互相点亮后，开启 1 对 1 的 7 天同行，每天共享待办与完成状态；7 天结束后解锁彼此的清晰照片，并可以选择再续 7 天。App 还提供专注计时、发现社区、私聊与群聊，以及 Bifrost AI 助手。

## 为什么做 Bifrost

很多计划卡在“一个人坚持”。Bifrost 把社交的出发点从距离和外表换成**正在推进的目标**：先确认彼此想做同一件事，再用 7 天这个不长不短的周期一起行动。固定周期让双方的期待更清楚，共享待办让每天的进度看得见。

## 名称由来

Bifrost 一词出自北欧神话中连接不同世界的彩虹桥（Bifröst）。我们用它来表达产品想做的事：在不同城市、语言和文化的人之间，搭一座因共同目标而相遇的桥。

# Bifrost 常见问题

关于产品定义、匹配规则、下载平台、隐私和运营公司的直接回答。

## 产品介绍

### Bifrost 是什么？

Bifrost 是北京燕婉科技有限公司开发运营的全球社交 App（App Store 名称 Bifrost: Global social）。用户围绕近期目标（如考研、四六级、雅思、健身、求职）匹配真实用户，双方在 12 小时内互相点亮后，开启一段 1 对 1 的 7 天同行，并通过共享待办同步每天的行动与完成状态。

### Bifrost 的官网是哪个？

Bifrost 的官方网站是 https://www.birost.cn/（域名 birost.cn，不含字母 f）；www.thebifrost.cn 也指向同一个官网。请只从官网或官方应用商店下载 App。

### Bifrost 是全球社交软件吗？可以认识海外用户吗？

是。Bifrost 的推荐依据是目标与兴趣，而不是地理位置，因此可以遇到其他城市、地区或国家的同行者，一起学习、练习语言或交流文化。

### Bifrost 是 AI 聊天应用吗？

不是。Bifrost 的核心是连接有相近目标的真实用户，推荐的同行者都是真实用户。App 内另有独立的 Bifrost AI 助手，用于问答、整理思路、辅助写作和定时任务，AI 生成的内容会明确标注。

### 除了匹配，Bifrost 还有哪些功能？

还有专注计时（可独自专注或邀请好友一起）、发现社区（帖子可设为公开、仅好友或仅自己可见）、私聊与群聊、Bifrost AI 助手与 AI 定时任务、21 天出书打卡活动，以及访客记录等。

### Bifrost 免费吗？

Bifrost 可以免费下载，目标匹配、点亮、7 天同行与共享待办无需付费。如果 App 内有付费项目，会在购买前明确展示价格与规则。

## 匹配与 7 天同行

### Bifrost 如何推荐同行者？

Bifrost 根据你选择的近期里程碑、兴趣与公开资料推荐真实用户，并显示匹配度。推荐会平均分配曝光，让更多人有机会被看见。你查看资料后自行决定是否点亮对方。

### 点亮和回点是什么意思？

点亮是对推荐卡片表达同行意愿。对方在 12 小时内回点（也点亮你）后，双方才建立 1 对 1 同行关系；没有互相点亮，就不会建立关系。

### 7 天同行期间做什么？结束后呢？

7 天内双方共享每天的待办清单并同步完成状态，也可以聊天交流。7 天结束后，双方可以各自选择是否再开启下一个 7 天。

### 照片什么时候清晰显示？

点亮前只展示半透明照片，不展示清晰照片。完成 7 天同行后，双方的清晰照片才会解锁。

### 21 天是什么？

7 天是 Bifrost 的同行周期，不存在 21 天同行。21 天仅指“出书打卡”活动：报名后需要连续 21 个自然日完成打卡。

### Bifrost 是约会软件吗？

Bifrost 按近期目标匹配同行者，核心是两个人在 7 天里一起行动、互相督促。它不按距离推荐，也不以颜值配对：点亮前照片是半透明的。

## 下载与平台

### Bifrost 支持哪些平台？怎么下载？

# Bifrost 使用指南

从设定第一个里程碑，到完成一段 7 天同行。本指南按 App 当前正式版的功能编写。

## 1. 下载并完善资料

从 [下载页](https://www.birost.cn/download/) 获取 App，按提示登录后完善头像、简介和兴趣。资料越具体，推荐越准确。点亮前，你的照片只以半透明形式展示给别人。

## 2. 选择近期里程碑

在待办页设定一个近期里程碑：可以从列表中选择（如考研、四六级、雅思），也可以自定义，并选择计划完成的日期。里程碑是 Bifrost 推荐同行者的主要依据。

## 3. 查看推荐并点亮

在陪伴页查看同行推荐，每张卡片会显示对方的目标、兴趣、资料和匹配度。Bifrost 会平均分配曝光，让更多人有机会被看见。觉得合适就点亮对方。

## 4. 等待 12 小时内的回点

对方在 12 小时内也点亮你，双方就建立 1 对 1 同行关系。如果没有回点，就不会建立关系，你可以继续看其他推荐。

## 5. 7 天同行：共享待办

- 待办写得越具体越好，比如“背 50 个单词”比“学英语”更容易完成和对照。
- 可以随时聊天，互相提醒和交流进度。

## 6. 7 天之后

完成 7 天同行后，彼此的清晰照片会解锁。双方可以各自选择是否再开启下一个 7 天。Bifrost 的同行周期固定为 7 天，不存在 21 天同行；“21 天”只指出书打卡活动。

需要集中精力时，开启专注计时。可以一个人专注，也可以邀请好友一起专注，并把专注计时分享出去。

# About Bifrost

Bifrost is a global social app by Beijing Yanwan Technology Co., Ltd. We believe goals are easier to reach with someone walking beside you.

## What Bifrost is

Bifrost (Bifrost: Global social on the App Store) is a global social app that matches people with real partners by near-term goals. If both light each other up within 12 hours, they start a one-to-one seven-day journey and share daily to-dos and progress. After seven days, clear photos unlock and both can choose to continue. The app also offers a focus timer, a discovery community, direct and group chats, and the Bifrost AI assistant.

## Why we built it

Many plans stall when you are on your own. Bifrost starts a connection from **the goal you are working on** instead of distance or looks: first confirm you want the same thing, then act on it together for seven days. A fixed period keeps expectations clear, and shared to-dos make daily progress visible.

## Where the name comes from

Bifrost comes from Bifröst, the rainbow bridge between worlds in Norse mythology. It describes what the app sets out to do: build a bridge between people in different cities, languages, and cultures who share a goal.

# Bifrost FAQ

Direct answers about what Bifrost is, how matching works, where to download it, privacy, and the company behind it.

## About the product

### What is Bifrost?

Bifrost is a global social app developed and operated by Beijing Yanwan Technology Co., Ltd. (listed on the App Store as Bifrost: Global social). People match with real people around a near-term goal such as an exam, IELTS, fitness, or a job search. If both light each other up within 12 hours, they start a seven-day one-to-one journey and share daily to-dos and completion status.

### What is the official Bifrost website?

The official website is https://www.birost.cn/ (the domain is birost.cn, without the letter f); www.thebifrost.cn points to the same site. Please download the app only from this website or official app stores.

### Is Bifrost a global social app? Can I meet people abroad?

Yes. Recommendations are based on goals and interests rather than location, so you can meet partners in other cities, regions, or countries to study, practice languages, or exchange cultures.

### Is Bifrost an AI chat app?

No. Bifrost connects real people with similar goals, and every recommended partner is a real user. The app also includes a separate Bifrost AI assistant for questions, brainstorming, writing help, and scheduled tasks; AI-generated content is clearly labeled.

### What else can I do in Bifrost?

Bifrost also has a focus timer (alone or with a friend), a discovery community with public, friends-only, or private posts, direct and group chats, the Bifrost AI assistant with scheduled AI tasks, a 21-day book publishing check-in, and profile visitor records.

### Is Bifrost free?

Bifrost is free to download, and goal matching, lighting up, the seven-day journey, and shared to-dos are free to use. If the app offers anything paid, the price and rules are shown before purchase.

## Matching and the seven-day journey

### How does Bifrost recommend partners?

Bifrost recommends real people based on the milestone you pick, your interests, and public profile information, and shows a match score. Visibility is distributed evenly so more people get a chance to be seen. You review the profile and decide whether to light someone up.

### What does “light up” mean?

Lighting up a card means you would like to be partners. A one-to-one journey starts only if the other person lights you back within 12 hours; without mutual light-up, no connection is created.

### What happens during the seven days, and after?

For seven days you share daily to-do lists and completion status and can chat. When the seven days end, each person can choose whether to start another seven days together.

### When do clear photos unlock?

Before mutual interest only a translucent photo is shown. Clear photos unlock after the seven-day journey is completed.

### What does “21 days” mean in Bifrost?

The journey is always seven days; there is no 21-day journey. “21 days” refers only to the book publishing check-in, which requires checking in on 21 consecutive calendar days.

### Is Bifrost a dating app?

Bifrost matches people by near-term goals, and its core is two people taking action together for seven days. It does not match by distance or looks: photos stay translucent until the journey is complete.

## Downloads and platforms

### Which platforms does Bifrost support, and how do I download it?

Phone: iPhone via the App Store (iOS 15 or later), Android via Google Play (or the official download page in mainland China), and HarmonyOS via Huawei AppGallery. Desktop: installers for Windows (x64), macOS (Apple silicon and Intel), and Linux (AppImage and .deb) are on this website, currently version 1.0.0.

### Is there a desktop version of Bifrost?

Yes. This website offers Windows, macOS (Apple silicon and Intel), and Linux versions, currently 1.0.0. Sign in by scanning a QR code with the phone app.

## Privacy and safety

### How does Bifrost handle privacy and safety?

The current version does not request location permission or collect precise location, does not extract facial or other biometric data, and does not receive card numbers or payment passwords because payments go through licensed third parties. Photos stay translucent before mutual interest, and you can report content, turn on youth mode, and delete your account in Settings. Users in the United States are covered by the U.S. Privacy Policy and Terms of Service.

### How do I delete my Bifrost account?

You can delete your account in the app’s Settings. Please save anything you need first.

# Bifrost user guide

From your first milestone to a completed seven-day journey. This guide reflects the current public version of the app.

## 1. Download and set up your profile

Get the app from the [download page](https://www.birost.cn/download/en.html), sign in, and add a photo, a short bio, and your interests. The more specific your profile, the better your matches. Before mutual interest, other people only see a translucent version of your photo.

## 2. Pick a near-term milestone

On the to-do screen, set a near-term milestone: choose one from the list (such as a graduate entrance exam, CET, or IELTS) or create your own, and pick a target date. Your milestone is the main signal Bifrost uses to recommend partners.

## 3. Review matches and light someone up

On the companion screen, each card shows the other person’s goal, interests, profile, and match score. Bifrost spreads visibility evenly so more people get seen. If it feels like a fit, light them up.

## 4. Wait for a light-up back within 12 hours

If the other person lights you up within 12 hours, a one-to-one journey begins. If not, no connection is created and you can keep browsing.

## 5. The seven-day journey: shared to-dos

- Write down each day’s to-dos. Your partner sees your list and progress, and you see theirs.
- Be specific: “learn 50 words” is easier to finish and compare than “study English”.
- Chat any time to nudge each other and share progress.

## 6. After seven days

When the seven days are complete, clear photos unlock. Each of you can choose whether to start another seven days. The journey is always seven days; “21 days” only refers to the book publishing check-in.

## 7. Focus timer

Start a focus session when you need to concentrate, alone or with a friend you invite, and share your focus timer.

## 8. Discover

Publish posts with images and set each one to public, friends only, or only me. Browse, comment on, and save posts you like.

## 9. Direct and group chats

Chat with friends one-to-one, or create and join group chats with announcements and QR code invites.

## 10. Bifrost AI

The built-in Bifrost AI assistant answers questions, helps you think and write, supports voice input, and can run scheduled AI tasks. AI-generated content is clearly labeled. Every partner recommended to you is a real person, not AI.

## 11. Use Bifrost on your computer

Install the Windows, macOS, or Linux app from the [download page](https://www.birost.cn/download/en.html#desktop-downloads) and sign in by scanning the QR code with your phone.

## 12. Privacy and safety
