一个人靠'氛围编程'做了一款健身 App
One dev 'vibe-coded' a fitness app
FitWit AI
你听说过'氛围编程'吗？
就是不画架构图，想到哪写到哪
有个独立开发者就用这种方式
做了一款带 Apple Watch 支持的健身 App——关键是
它居然真能用
Ever heard of 'vibe coding'?
No architecture, just building as you go. One
indie dev did exactly that — and shipped
a fitness app with Apple Watch support that
actually works
运动+饮食+手表，一站搞定
Workouts + Meals + Watch
市面上的健身 App 要么只管训练
要么只管饮食，跟手表还经常不互通
大多数人用着用着就放弃了
FitWit 的思路很简单——把训练记录
饮食追踪
Apple Watch 同步塞进一个 App
形成一个完整的闭环
Most fitness apps pick a lane — workouts
or nutrition. FitWit does both, plus Apple Watch
sync. One closed loop, because that's how fat
loss actually works
★ SIGNAL 1
拍张照就能记饮食
Snap a photo, log your meal
最让我觉得有'产品脑'的地方——饮食记录
大多数人记了两天就烦了
因为要手动搜食物、输克数
FitWit 用 AI 拍照识别
你拍一张，它自动估算热量和营养成分
这才是真正在解决'坚持不下去'的问题
The product-brain move: food logging. Most people quit
tracking meals because searching databases is tedious. FitWit
uses AI to identify food from a photo
and estimate calories automatically. It's solving the real
problem — people giving up
★ SIGNAL 2
Apple Watch 不是摆设
Watch support, not a checkbox
很多人觉得加个 Apple Watch 支持就是打个勾的事
实际上 HealthKit 权限
传感器 API、前台后台同步
每一项都是坑
一个'氛围编程'写出来的 App
能做到手表数据实时同步还拿 5.0 分——这手艺不是吹的
Adding Watch support isn't a checkbox — it
means HealthKit permissions, sensor APIs, foreground and background
sync. Shipping something this polished while 'vibe coding'?
That's real hands-on skill
这个开发者很实在
帖子标题直接写的就是'Vibe coded iOS workout app with Apple Watch support'——没有任何包装
没有'革命性'、没有'颠覆'
就是老老实实告诉你
这玩意儿是我想着写着做出来的
The dev literally titled his post 'Vibe coded
iOS workout app with Apple Watch support.' No
marketing fluff, no 'revolutionary.' Just honest from the
first word
