痛点：牙医每天被患者问“这个饮料能喝吗”，却没有快速查酸蚀/含糖风险的工具，患者也缺乏针对牙齿健康的饮料评估标准。

目标用户：关注牙齿健康与酸蚀/龋齿风险的普通消费者、正畸/种植/牙敏感人群，以及愿意向患者推荐工具的牙医和口腔诊所。

证据："Patients ask me 'is this one okay?' every day, and for most of my career the honest answer was 'I'd have to look it up.'" / "a 7-day trial, then Plus at $0.99/month for scanning and the journal, or Pro at $1.99/month or $19.99/year for everything" / "14 App Store rejections before it went live"

变现：订阅制（$0.99/月基础档、$1.99/月或$19.99/年专业档含餐食扫描）；后续可做牙科诊所白标/转介导流分成、品牌饮料厂商的配方优化认证（付费收录）。

MVP：用 Open Food Facts/USDA 开放条码与营养数据做底库，2周内实现：条码扫描 → 按酸蚀(pH/柠檬酸)、每份含糖量、碳酸化、酒精、含氟/钙/磷五个维度加权算 0-100 分 → 红黄绿等级 + 一句替换建议；不做卡路里与饮食记录，重点打磨扫描命中率和“查不到时让用户补条码”的众包闭环。
