+
+## 📝 详细代码修改
+
+### 1. `utils/storage.js` - 新增常量
+
+```javascript
+export const USER_MODE_KEY = 'user_mode'  // 新增
+```
+
+---
+
+### 2. `stores/user.js` - 扩展用户模式
+
+```javascript
+import { defineStore } from 'pinia'
+import { storage, USER_KEY, SESSION_KEY, USER_MODE_KEY } from '@/utils/storage'
+
+export const useUserStore = defineStore('user', {
+  state: () => ({
+    user: storage.get(USER_KEY),
+    sessionKey: storage.get(SESSION_KEY),
+    isLoggedIn: !!storage.get(SESSION_KEY),
+    mode: storage.get(USER_MODE_KEY) || null  // 'quit' | 'record' | null
+  }),
+
+  actions: {
+    setUser(user, sessionKey) {
+      this.user = user
+      this.sessionKey = sessionKey
+      this.isLoggedIn = true
+      storage.set(USER_KEY, user)
+      storage.set(SESSION_KEY, sessionKey)
+    },
+
+    setMode(mode) {
+      this.mode = mode
+      storage.set(USER_MODE_KEY, mode)
+    },
+
+    logout() {
+      this.user = null
+      this.sessionKey = null
+      this.isLoggedIn = false
+      storage.remove(USER_KEY)
+      storage.remove(SESSION_KEY)
+    }
+  }
+})
+```
+
+---
+
+### 3. `pages.json` - 添加新页面
+
+```json
+{
+  "pages": [
+    {
+      "path": "pages/mode-select/index",
+      "style": {
+        "navigationStyle": "custom"

+const modeText = computed(() => {
+  return userStore.mode === 'quit' ? '戒烟打卡' : '记录抽烟'
+})
+
+function showModeSwitch() {
+  uni.showActionSheet({
+    itemList: ['戒烟打卡模式', '记录抽烟模式'],
+    success: (res) => {
+      const modes = ['quit', 'record']
+      userStore.setMode(modes[res.tapIndex])
+      uni.showToast({ title: '已切换', icon: 'success' })
+    }

+
+## 📋 开发顺序
+
+| 阶段 | 任务 | 预估时间 | 状态 |
+|------|------|----------|------|
+| **第一阶段** | 1. 修改 `utils/storage.js`<br>2. 修改 `stores/user.js`<br>3. 创建 `pages/mode-select/index.vue`<br>4. 修改 `pages.json` | 1-2h | ⬜ 待开始 |
+| **第二阶段** | 1. 创建 `pages/quit-home/index.vue`<br>2. 打卡 API 对接<br>3. 省钱金额计算 | 2-3h | ⬜ 待开始 |
+| **第三阶段** | 1. 创建 `pages/record-home/index.vue`<br>2. 一键记录 API 对接 | 1-2h | ⬜ 待开始 |
+| **第四阶段** | 1. 修改 `pages/profile/index.vue` 模式切换<br>2. 修改引导流程跳转逻辑 | 1h | ⬜ 待开始 |
+
+**总预估：5-8 小时**
+
+---
+
+## ⚠️ 注意事项
+
+### 1. TabBar 问题
+
+如果要让两种模式共用 TabBar，首页需要根据 mode 动态渲染：
+
+```vue
+<!-- pages/index/index.vue -->
+<template>
+  <QuitHome v-if="userStore.mode === 'quit'" />
+  <RecordHome v-else />
+</template>
+```
+
+### 2. 数据兼容
+
+老用户没有 mode 字段，需要引导选择模式：
+
+```javascript
+// App.vue 或首页
+if (!userStore.mode) {
+  uni.redirectTo({ url: '/pages/mode-select/index' })
+}
+```
+
+### 3. API 对接
+
+打卡功能需要后端新增接口：
+
+```
+POST /api/checkin
+{
+  "date": "2026-03-17",
+  "quit_days": 23
+}
+```
+
+或复用现有 resisted 接口。

+| **付费场景** | 高级AI、戒烟计划、专家咨询 | 会员特权、定制海报 | smt胜 ⭐⭐⭐⭐⭐ |
+| **广告场景** | 戒烟产品、健康产品 | 戒烟产品 | 平手 ⭐⭐⭐ |
+| **增值服务** | 数据报告、专家咨询 | 较少 | smt胜 ⭐⭐⭐⭐ |

+
+## 🔍 核心问题诊断
+
+### 为什么 smt 日活少？
+
+#### 人性因素分析
+
+| 人性因素 | 具体表现 |
+|----------|----------|
+| **懒惰** | 每次抽烟都要打开小程序记录，太麻烦 |
+| **遗忘** | 抽烟是无意识行为，抽完就忘了记录 |
+| **逃避心理** | 记录=承认自己又抽了，心理负担重 |
+| **即时反馈弱** | 记录后没有即时奖励，动力不足 |
+| **挫败感** | 越记录越发现自己抽得多，想放弃 |
+
+**本质问题：产品要求用户"主动做额外的事"，而人是厌恶"额外负担"的。**
+
+---
+
+## 💡 PM 建议（2026-03-17）
+
+### 🎯 决策：全力转向 quit-checkin
+
+**核心理由：戒烟产品本质是"情绪按摩"，不是"数据监控"**
+
+| 维度 | smt | quit-checkin |
+|------|-----|--------------|
+| **心理契合** | 记录=审计失败 ❌ | 打卡=奖励成功 ✅ |
+| **传播力** | 没人分享抽烟记录 ❌ | 愿意分享"戒烟100天" ✅ |
+| **维护成本** | AI+统计，成本高 ❌ | 逻辑简单，好维护 ✅ |
+| **获客成本** | 高 ❌ | 自带裂变，0成本 ✅ |
+
+### 具体操作建议
+
+#### 1. 不要废弃 smt，而是"取其精华"
+
+把 smt 的高价值功能**降维**嵌入 quit-checkin：
+
+| smt 功能 | 如何嵌入 quit-checkin |
+|----------|----------------------|
+| 健康恢复指标 | 打卡满X天解锁视图 |
+| AI 建议 | 只在"快忍不住了"时弹出应急 |
+| 省钱账单 | 打卡页实时显示"已省XX元" |
+
+#### 2. 运营迁移
+
+- smt 首页加提示：**"轻量版上线，试试更简单的无烟打卡"**
+- 老用户可将 smt 数据同步到 quit-checkin（保留成就感）
+
+#### 3. quit-checkin 迭代重点
+
+- **视觉溢价**：把分享海报做得高级，让用户有面子
+- **梦想激励**：打卡省下的钱填补梦想进度条（如：给女儿买钢琴）
+- **仪式感**：打卡动效、勋章音效，让用户对"点一下"上瘾
+
+---
+
+## 🚀 改造方案：smt 双模式
+
+### 核心思路
+
+在现有 smt 基础上快速迭代，而不是推倒重来：
+
+1. **首次启动引导**：让用户选择"戒烟打卡"或"记录抽烟"
+2. **根据选择切换首页**：不同模式展示不同界面
+3. **保留历史数据**：用户历史数据兼容
+
+### 优势
+
+| 维度 | 说明 |
+|------|------|
+| **用户不流失** | 现有用户平滑过渡，无需迁移 |
+| **开发成本低** | 复用现有代码，增量修改 |
+| **数据保留** | 用户历史数据不丢失 |
+| **快速验证** | 改动小，可以快速上线测试 |
+
+---
+
+### 首次启动引导设计
