-# SkinLab
+
+
+
-AI-powered skin analysis and skincare recommendation iOS app.
+**SkinLab** 是一款 iOS 17+ 的皮肤记录与护肤效果追踪应用。它把一次 AI 照片分析变成可重复的基线:标准化拍摄、记录产品与生活方式、按周期复拍,再用可靠性与趋势模型解释变化。
-## Overview
+> **隐私与医疗边界:** AI 分析不是离线完成。点击分析后,压缩后的面部照片会以 base64 JPEG 发送到 OpenRouter 的 chat-completions API,当前模型为 `google/gemini-3-flash-preview`。结果只供护肤记录参考,不构成医疗诊断;异常皮肤问题应咨询专业医护人员。
-SkinLab helps users understand their skin health through AI-powered analysis and track skincare effectiveness over a 28-day verification cycle. The app focuses on data-driven insights that users want to share.
+## 从照片到证据
-**Core Philosophy**: Make skincare effects visible ("让护肤效果看得见")
+```text
+标准化拍照
+ → 质量 / 可靠性检查
+ → OpenRouter + Gemini vision 分析
+ → SwiftData 保存结果与基线
+ → 复拍 + 产品 / 生活方式记录
+ → 趋势、异常、季节性与相关性提示
+```
-**Target Users**: 18-35 year olds focused on skincare
+仓库中的真实功能模块:
-**Differentiation**:
-- Effect verification engine with 28-day tracking cycles
-- Skin twin matching for personalized recommendations
-- Anti-ad commitment - evidence-based suggestions only
+| 模块 | 当前源码 |
+|---|---|
+| Analysis | 相机/相册、图片优化、OpenRouter 请求、皮肤与区域分数、routine generation |
+| Tracking | 28 天 session、check-in、可靠性、time series、异常/季节性/forecast、产品归因 |
+| Products | 本地产品/成分数据、OCR、风险规则与 AI insight |
+| Engagement | 连续记录、streak freeze、achievement、提醒与庆祝动画 |
+| Community | consent level、匿名 profile、skin twin matching、反馈与推荐 engine |
+| Privacy | 本地存储开关、照片保留/删除、数据导出与全量删除入口 |
-## Features (Completed)
+这些是源码能力,不代表 App Store 已发布或临床验证。
-### fn-2: Engagement (Daily Streaks & Achievement Badges)
-- Daily streak tracking for check-ins with longest streak display
-- Achievement badges and dashboard for milestones
-- Milestone celebration animations (respects reduced motion)
-- Streak freeze mechanic (1 per 30 days)
-- Local notifications for streak reminders and at-risk warnings
+## 快速开始
-### fn-3: Photo Standardization & Lifestyle Correlation
-- Day 0 baseline creation to start tracking sessions from analysis
-- Standardized photo capture guidance with real-time feedback
-- Photo quality and reliability scoring at capture time
-- Lifestyle inputs are optional and only saved when explicitly set
-- Lifestyle correlation insights based on real score deltas
+要求:
-## Tech Stack
+- macOS + Xcode **15.2**(CI 固定版本)
+- iOS **17.0+** simulator 或设备
+- OpenRouter API key
-| Component | Technology |
-|-----------|------------|
-| Platform | iOS 17+ |
-| Language | Swift 5.9+ |
-| UI Framework | SwiftUI |
-| Architecture | MVVM + Clean Architecture |
-| Storage | SwiftData |
-| AI | Gemini 3.0 Flash Vision API |
-| Image Processing | Vision Framework |
+```bash
+git clone
+cd SkinLab
+open SkinLab.xcodeproj
+```
-## Getting Started
+在 Xcode 中选择 `SkinLab` scheme 与 iOS 17 simulator。开发运行时,在 **Product → Scheme → Edit Scheme → Run → Arguments → Environment Variables** 添加:
-### Requirements
+```text
+OPENROUTER_API_KEY=
+```
-- Xcode 15.0+
-- iOS 17.0+ deployment target
-- Swift 5.9+
-- Gemini API key (see `Secrets.xcconfig.template`)
+然后 Build & Run。`GeminiService` 会先读取进程环境变量,再读取 Info.plist 中由 build setting 展开的 `OPENROUTER_API_KEY`。
-### Setup
+仓库保留了 `Secrets.xcconfig.template`,但当前 `project.pbxproj` 没有把 `Secrets.xcconfig` 设为 base configuration;**仅复制模板不会自动注入 key**。若需要 archive,应在 Xcode build settings/CI secret 中显式提供该值,且不要提交 key。
-1. Clone and open the project:
- ```bash
- git clone
- cd SkinLab
- open SkinLab.xcodeproj
- ```
+命令行构建:
-2. Configure secrets:
- - Copy `Secrets.xcconfig.template` to `Secrets.xcconfig`
- - Set your API key in the new file (see template for key name)
- - Do NOT commit `Secrets.xcconfig` to version control
+```bash
+xcodebuild build \
+ -project SkinLab.xcodeproj \
+ -scheme SkinLab \
+ -destination 'platform=iOS Simulator,name=iPhone 15' \
+ CODE_SIGNING_ALLOWED=NO \
+ OPENROUTER_API_KEY=''
+```
-3. Build and run on simulator or device:
- ```bash
- xcodebuild -scheme SkinLab -destination 'platform=iOS Simulator,name=iPhone 15'
- ```
+## 第一次使用
-### Running Tests
+1. 允许相机或相册权限。
+2. 按拍摄引导保持光线、角度与清晰度,创建一次分析。
+3. 在分析结果中查看分区与问题维度;不要把分数视为医学结论。
+4. 从分析结果建立 tracking baseline,并只填写真实使用的产品/生活方式信息。
+5. 后续 check-in 尽量复用相同拍摄条件,再查看可靠性与趋势,而不是比较任意两张照片。
+6. 在 Profile → Privacy Center 检查 consent、照片保留、导出和删除选项。
-```bash
-xcodebuild test -scheme SkinLab -destination 'platform=iOS Simulator,name=iPhone 15'
-```
+### 重要隐私事实
-## Project Structure
+- SwiftData 保存分析、追踪、产品与 profile records。
+- 原图是否在设备侧保留由 Privacy Center 选项控制。
+- **AI 请求仍会把压缩图发送给 OpenRouter**;“本地优先”不等于 vision inference 完全离线。
+- 社区匹配使用 consent level 与匿名 profile 模型,但使用前仍应审查具体数据流与部署配置。
