突破点和好做增强

下一轮突破点

  • 当前判断：`WATCH`。先验证 `fast ad-light PDF opener + image-to-PDF for students/office`，不做广告重压或 all-files access 泛化。
  • 文件处理风险 | 少量文件消失/重新下载片段，强证据少 | 真机验证文件权限和本地处理
  • 1 周 MVP：Android 文件选择/本地 PDF 列表、成熟 PDF renderer、页面跳转、书签、夜间模式、image-to-PDF。
  • 1 个月 MVP：PDF to image、基础注释、搜索、最近文件、默认打开 intent、崩溃监控、无广告订阅。
  • 真机验证首开、文件权限、广告和 IAP | validation-analyst | manual | 2026-06-16
  • 设计 ad-light PDF opener MVP | app-dissector | manual | 2026-06-16

好做且高价值

  • Hooks | 快速打开 PDF、大文件/密码 PDF、图片/收据/笔记转 PDF、轻量 office app、一站式文档管理 | verified / inferred
  • 客服 / 退款 | support website 是 Firebase 默认页，退款评论不满意 | 信任短板明显
  • 主 hook：快速打开本地 PDF、支持大文件/密码 PDF、图片转 PDF、轻量 office app。
  • 素材模式：急需打开文件 -> 快速阅读/搜索/转 PDF -> 去广告升级。
  • 1 周 MVP：Android 文件选择/本地 PDF 列表、成熟 PDF renderer、页面跳转、书签、夜间模式、image-to-PDF。
  • 3 个月版本：OCR、压缩、签名、合并/拆分、可选云同步、学生/office 模板。
  • support website/隐私模板质量影响信任 | 单看下载会漏退款风险 | 增加 support/privacy/data deletion 合规评分 | backlog_open

评论痛点图谱

Cluster证据机会 / 风险
误导免费 / 订阅IAP verified，评论有误订阅和退款失败不如 Cleaner 系统性，但要明确 remove ads/premium
文件处理风险少量文件消失/重新下载片段，强证据少真机验证文件权限和本地处理
性能 / 崩溃多条评论抱怨打开慢、广告后回不来ad-light 是 wedge
效果不符承诺轻量/快速，实际打开文档被广告打断首次任务成功率比功能多更重要
客服 / 退款support website 是 Firebase 默认页，退款评论不满意信任短板明显
