I built a period tracker that stores everything on your phone (no account, no ads, no internet permission)

I'm a solo dev and I just shipped Saumya, an Android period tracker. I got tired of cycle trackers that want an account, show ads or sync health data to a server, so I built one where that's impossible: the app has no INTERNET permission at all. What it does: - Log period, flow, symptoms, mood and notes in a few taps - Shows a range of dates for your next period (an estimate, not a falsely exact day) - Calendar and history - Optional PIN / fingerprint lock and a discreet mode (neutr

AI 分析

痛点:主流经期追踪App要求注册账号、展示广告并把健康数据同步到服务器,注重隐私的用户不愿承担数据被收集或泄露的风险。

目标用户:重视隐私的经期记录用户,尤其是对健康数据上云敏感的女性;偏好无账号、无广告、纯离线工具的人群。

证据:I got tired of cycle trackers that want an account, show ads or sync health data to a server, so I built one where that's impossible: the app has no INTERNET permission at all.

变现:免费基础版 + 一次性买断(约 3-6 美元)解锁加密备份、多档案、更多语言;不引入广告和订阅,以免破坏隐私卖点。也可考虑开源 + 捐赠。

MVP:用 Kotlin/Compose + Room 做纯离线记录:经期、流量、症状、情绪,预测日期区间展示,PIN/指纹锁,本地导出加密备份文件;不申请 INTERNET 权限并把这一点作为核心卖点展示。

竞品:Flo、Clue、Drip、Euki、Periodical、Spot On (Planned Parenthood)

摘要:独立开发者发布免费 Android 经期追踪 App Saumya,主打无 INTERNET 权限、无账号、无广告,数据全部存在本地,支持 PIN 与指纹锁、加密备份、英语和印地语。痛点真实,但该赛道已有 Drip、Euki、Periodical 等隐私向竞品,且用户普遍预期经期 App 免费,帖子中没有任何付费意愿或收入证据,变现空间有限。
