AI 分析

痛点:macOS 只显示“System Data”,用户不知道存储空间被什么占用、为什么变化,清理后缓存又会迅速回来。

目标用户:MacBook 存储空间紧张的用户,尤其是开发者、设计师和普通 Mac 用户。

证据:My MacBook Air was down to 10 GB free, and macOS just kept saying "System Data" without telling me what had changed or why. 31 GB was app caches... 14-day free trial, then $9.99/£7.99 once.

变现:一次性买断制(如 $9.99/£7.99),可配合 14 天免费试用;或采用免费扫描+付费解锁历史对比/缓存追踪。

MVP:2 周内做一个 macOS 菜单栏工具:定期扫描并保存存储快照,突出显示新增/异常增长的大目录和缓存,删除前必须人工确认并先移入废纸篓。

竞品:CleanMyMac X、DaisyDisk、OmniDiskSweeper、GrandPerspective、Disk Inventory X

摘要:英国独立开发者发布 DiskFox,解决 macOS 只显示“System Data”导致用户不知道存储去向的问题;他展示了自己 Mac 上 31 GB 应用缓存、Spotify 缓存一周回涨 890 MB 等发现。产品采用 14 天免费试用后 $9.99/£7.99 一次性付费模式。Mac 存储清理赛道竞品较多,但“存储历史对比+缓存追踪”仍有细分空间。
