I built an iPhone app that turns document expiry dates into reminders — without keeping the photo

reddit SideProject · 原文链接 ↗ · 54 分

Expiry dates tend to live in the one place I never check again: the document itself. So I built DueCalm for iPhone. Take a photo of a passport, insurance policy, licence, warranty, or another dated document. DueCalm: • uses AI to suggest the expiry date • shows the exact source line it read so you can verify it • lets you correct and confirm the date before saving • creates local reminders and an optional calendar event • discards the source photo after processing • requires no account Manual reminders are free. Document scanning has a 7-day free trial, then costs $19.99

痛点：证件、保单、驾照、保修卡等文件的到期日容易被遗忘，而手动记录提醒又麻烦。

目标用户：经常需要管理证件/保单/保修到期日的个人用户，尤其是注重隐私、不想上传文件照片的人。

证据：Expiry dates tend to live in the one place I never check again: the document itself. ... Manual reminders are free. Document scanning has a 7-day free trial, then costs $19.99/year.

变现：订阅制：基础手动提醒免费，AI 文档扫描与到期日提取按 $19.99/年收费，或提供一次性买断/低价年费。

MVP：2 周内做一个 iPhone MVP：拍照后调用 OCR/多模态 API 提取到期日，展示原文行供确认，保存本地提醒和可选日历事件，处理完立即删除原图，无需账号。

竞品：iOS Reminders/Calendar、CamScanner、Expiry Reminder 类应用、Google Keep

摘要：发帖人发布了 iPhone 应用 DueCalm，把护照、保单、驾照、保修卡等文件的到期日通过拍照识别转成本地提醒，处理后删除原图且无需账号。手动提醒免费，文档扫描 7 天试用后 $19.99/年。帖子没有展示实际付费用户数、收入或他人需求附和，需求验证较弱，但痛点明确且独立开发者可做类似 MVP。
