My OCD couldn't stand spam SMS clutter, so I built this!

reddit SideProject · 原文链接 ↗ · 52 分

The annoying part isn't just the alerts—it's that most apps still save spam to your phone's database under a "Spam" folder. So I built Heimdall 🛡️—a lightweight Android SMS app that silently kills spam before it even touches your system storage. Primary features: Silent drop: Spams are never written to the phone's SMS database. Zero noise: Zero vibrations, rings, or notification icons for spam. Auto-cleanup: Quarantined spam auto-deletes after 30 days. 1-tap OTP copy: Quick copy button directly on the notification. 100% offline: No internet permissions. Source code: h

痛点:垃圾短信不只是打扰,而是被系统/多数拦截 App 以“Spam”文件夹形式写进手机短信数据库,用户既无法彻底清除也没法静音归档。

目标用户:被垃圾短信/营销短信长期骚扰的 Android 用户,尤其是注重隐私(要求离线、无网络权限)和有“数字洁癖”的重度使用者。

证据:The annoying part isn't just the alerts—it's that most apps still save spam to your phone's database under a "Spam" folder. / Silent drop: Spams are never written to the phone's SMS database. / 100% offline: No internet permissions.

变现:开源版免费+捐赠;商业化可走一次性买断的 Pro(高级关键词/正则规则、云端规则库订阅更新、多设备规则同步、白名单与银行验证码保护),或与隐私类工具做联盟分发。注意 Google Play 对 SMS 权限仅开放给默认短信应用,需先成为默认短信 App 才能拿到权限。

MVP:2 周内可在其开源代码基础上做一个“规则订阅”版本:内置可远程更新的垃圾短信关键词/正则规则包(本地执行、不联网读取内容),提供一键导入导出规则、误杀回收站(30 天可恢复)、验证码一键复制,并以订阅制出售规则库更新服务。

竞品:Google Messages 内建垃圾信息过滤、Truecaller、RoboKiller、TextKiller (iOS)、Should I Answer、各类国产手机系统自带短信拦截

摘要:一位独立开发者因受不了垃圾短信在手机短信库里堆积,做了开源 Android 短信 App Heimdall:垃圾短信在写入系统数据库前就被静默丢弃,无震动/铃声/通知,隔离 30 天后自动删除,且申请零网络权限。帖子展示了明确且真实的个人痛点,但产品本身免费开源,全文没有任何付费意愿或收入数据,也没有评论热度数据佐证需求规模。痛点真实、单人 2 周可复刻,但系统自带过滤和 Truecaller 等竞品已很密集,变现空间有限。
