I made a screen recorder that saves up to 2 minutes before you tap record.

Hey everyone, solo dev here. so this started because I kept missing stuff. I’d be playing something, a ridiculous glitch or a 1v3 clutch would happen, and by the time I opened a screen recorder and tapped start it was gone. the other option was recording for 40 minutes and scrubbing through all of it later, which I never actually did lol. PC has instant replay, consoles have it. I couldn’t find anything on android that did it the way I wanted, so I built it. it’s called Re

痛点：安卓上没有像 PC、主机那样“先缓冲、事后保存”的即时回放能力，精彩瞬间或崩溃现场往往在打开录屏前就消失了。

目标用户：安卓手游玩家、需要复现 bug 的用户、制作短视频和 Reels 的内容创作者。

证据：I couldn't find anything on android that did it the way I wanted, so I built it. / there's a pro version if you want longer buffers (up to 2 min), 1080p60, game audio, or vertical crop for shorts/reels, but the main thing works fine without paying.

变现：Freemium（免费增值）：免费 10 秒、720p 无水印，Pro 通过订阅或买断解锁最长 2 分钟缓冲、1080p60、游戏内录、竖屏裁剪。

MVP：用 Android MediaProjection 加环形缓冲做核心功能：常驻悬浮按钮，后台循环保留最近 30–60 秒画面，点一下导出“按下前 N 秒”的片段；本地存储、不上传、无水印；先把长缓冲、1080p、竖屏裁剪做成付费解锁。

竞品：AZ Screen Recorder、XRecorder、Mobizen

摘要：一位独立开发者因为安卓缺少“即时回放”功能，自己做了 Replay Buffer：点一下悬浮按钮，就能保存按下前最多 2 分钟的画面，免费版提供 10 秒、720p、无水印，Pro 解锁长缓冲、1080p60、游戏音频和竖屏裁剪。属于典型的工具类 freemium 机会，痛点和变现路径清晰，但帖子里没有真实收入或其他用户的付费佐证。
