EON - Subscription Tracker

项目介绍

EON 是一款订阅管理 App：把所有订阅收在一处，首页一眼看到本月/季/年的支出、月均与 lifetime 总额；每个订阅可设自定义提前提醒，试用到期、年费续订前收到通知；多币种按每日汇率自动换算；账单日历按天标注每笔扣款；订阅卡片自动抓取官方图标并按图标取色；另有主屏/锁屏小组件与 iCloud 同步。 作者磊郭（Leon Guo）非技术出身，在少数派长文《记了 10 年账，我还是决定自己 Vibe Coding 一款记账 App》里写道：“我实际在用的是 Claude 写代码，让 Codex 出图。”EON 是他的第一款 App，“纯免费，所有功能无限使用”，前后开发 2 个月（功能 1 周、UI 打磨与改 bug 占绝大部分），已迭代 10+ 个版本，当前 v1.2.2（两天前更新）。“完全免费无付费墙”，只留了纯打赏内购——作者说在免费+打赏模式下 0.3% 的打赏率“已经远超预期”。无账号、无服务器、不追踪，数据只在设备与自己的 iCloud。 EON is a subscription tracker that keeps every subscription in one place: home screen shows this month/quarter/year spend plus monthly average and lifetime total; custom lead-time reminders before every charge; multi-currency converted at daily rates; a billing calendar marking each charge; auto-fetched official icons that tint each card; home and lock-screen widgets and iCloud sync. Maker Leon Guo is non-technical — “I use Claude to write code and Codex for images.” EON was his first app, free with all features unlimited, now 10+ versions in (v1.2.2, updated 2 days ago). Completely free with no paywall — only optional tip-jar IAPs, which the author says convert at 0.3%, “far beyond expectations”. No account, no servers, no tracking.
