I built this two months ago while training for my half marathon. I like seeing the routes I've run (i like to mix em up), and turning them into a screensaver felt like a nice way to look back on the training. I hate subscriptions, so it is $7.99 once. Link below. Would love some feedback! What would you want to see alongside your routes? Link: http://tryretrace.app/ submitted by /u/ILikePainauChocolat [link] [comments]
痛点：Strava 跑者/骑行者想把训练路线变成 Mac 屏保来回顾，但缺少简单、一次性买断的桌面工具。
目标用户：使用 Mac 的 Strava 跑步、骑行爱好者，尤其是重视训练回顾且反感订阅的人。
证据：I hate subscriptions, so it is $7.99 once. / turning them into a screensaver felt like a nice way to look back on the training.
变现：一次性买断 $7.99；后续可加路线艺术打印、高级主题、多运动平台支持或 Pro 版。
MVP：2 周内用 Swift/Objective-C 做 macOS 屏保，接入 Strava OAuth 拉取活动 GPX，用 MapKit/Mapbox 渲染极简路线图，支持本地缓存、暗色模式和一次性买断许可。
竞品：Strava Route Art、VeloViewer、Relive、Statshunters、Retrace (该产品自身)
摘要：该帖子是独立开发者发布 Mac 屏保 Retrace，把 Strava 路线变成屏保，定价 $7.99 买断，因讨厌订阅。作者自述为半马训练回顾而做，但帖子中没有用户付费、收入或其他用户附和，需求验证仍弱。对独立开发者而言，这是一个可快速复制的 Mac 端 Strava 路线可视化小工具机会。
