I kept losing my friends at festivals, so I built an Android app that works without internet

I kept losing my friends at festivals, so I built an Android app that doesn't need the internet 🛰️ At large festivals and events I've always found the same thing happens: thousands of people arrive, mobile data becomes painfully slow or stops working entirely, and inevitably I wander off and lose everyone. So I wondered: what if finding your friends didn't depend on the mobile network at all? I built Offlink, an Android app that uses Bluetooth Low Energy to exchange location information

AI 分析

痛点:大型音乐节/活动中手机网络严重拥塞乃至完全断网,导致人们无法用现有定位应用找到同行朋友而走散

目标用户:音乐节、演唱会、大型赛事/集会参与者,以及户外、露营等无网络场景人群

证据:thousands of people arrive, mobile data becomes painfully slow or stops working entirely, and inevitably I wander off and lose everyone. / It's free. If you find a bug, something confusing, or just think something could work better, I'd genuinely like to hear it.

变现:免费增值:基础找人免费,群组多人实时共享、长时间位置历史、跨设备/跨平台(iOS)同步、离线消息等做订阅;或向音乐节主办方提供白标 B2B 方案(主办方为观众体验付费);也可做一次性解锁的高级版

MVP:2 周内砍掉多跳 mesh 复杂度,只做最短路径验证:单跳 BLE 广播 + 室内/操场实测,做一个"同一活动内可见朋友距离与大致方位(含电量/信号状态)"的 Android 极小版本,在本地一场活动上找 20 个真实用户跑通再迭代;技术难点集中在 BLE 扫描功耗与 Android 后台限制,应先解决这两点

竞品:Bridgefy、FireChat(已停运)、WhatsApp/微信实时位置共享、Apple Find My / Google Find My Device 网络、Jodel

摘要:开发者因在大型音乐节上反复与朋友走散(数千人涌入后移动数据变慢甚至完全断网),用几个月做出了 Offlink:基于 BLE 的 Android 离线找朋友 App,附近手机可组成小型 mesh 网络并多跳转发位置,无需流量/WiFi/联网,已通过 Google 封闭测试正式上架 Google Play。目前完全免费、无任何收费或收入数据,主要在招募真实场景测试者,说明需求真实但付费意愿尚未被验证。
