I kept building apps nobody searched for, so I built a tool to check the niche before I write code

Hi everyone, solo dev here. My pattern for years: get an idea, spend weeks building it, ship it, then find out nobody types those words into the App Store, or there are already 40 apps doing it. So this time I flipped the order. Before writing any app code, I wanted answers to: - What do people actually type when they search for this? (the keyword tree, not my guess) - How many apps already compete on each keyword? - What do users complain about in 1-2 star reviews of those apps?

AI 分析

痛点:独立开发者凭感觉选方向,做了几周上线后才发现关键词没有搜索量或竞品已饱和,缺少动手前低成本验证细分市场的工具。

目标用户:独立开发者与小团队 iOS/Android 开发者,尤其是做工具类、订阅类 App 的人

证据:"spend weeks building it, ship it, then find out nobody types those words into the App Store, or there are already 40 apps doing it" / "22 downloads so far, {N} paying users (sales opened Nov 1)" / "the review complaints were more useful than the keyword volumes"

变现:桌面工具一次性买断($19–49),叠加订阅版提供竞品关键词监控、差评痛点趋势和机会分提醒

MVP:2 周 MVP:输入一个关键词后抓取 App Store/Google Play 搜索建议树和相关竞品数量,抓取竞品 1–2 星评论做痛点词聚类,并拉取 Google Trends 判断热度趋势,本地 SQLite 存储并输出机会评分;使用 Electron 或 Tauri 做 Mac 桌面端,先不做账号体系和云端。

竞品:AppTweak、Sensor Tower、Appfigures、Mobile Action、App Store 关键词工具(如 Astro、Keyword Tool)

摘要:一位独立开发者反复做出“没人搜”的 App 后,做了本地 Mac 工具:整合 App Store、Google Play、Google Trends 数据,输出关键词树、竞品数量、差评痛点和机会评分。上线两周获 22 次下载,11 月 1 日开卖并已有付费用户(人数用占位符隐藏),作者强调差评抱怨比关键词搜索量更有用。这既暴露了开发者选方向前验证需求的真实痛点,也说明该细分已有付费验证。
