I built a fitness coach I just talk to. It logs Indian food to the gram and plans my week around office days

I say "two small rotis and a katori of paneer bhurji" and it logs grams, calories and protein. Pasting a Zomato order uses the listed nutrition values instead of guessing. The main design rule was that the LLM never does math. It parses what I said and explains things. Grams, macros, workout loads and limits are all calculated in code. Unknown foods get estimated, validated, and then saved to my own food catalogue so the next lookup isn't a guess. The hard part was trusting

AI 分析

痛点:印度食物(roti、katori、paneer bhurji、Zomato 外卖)很难在主流卡路里 App 里准确记录到克数和蛋白质,语音口述后还需自己算数。

目标用户:在南亚饮食环境下做增肌或减脂的健身人群,特别是常吃家常菜和 Zomato 外卖的城市上班族。

证据:I say "two small rotis and a katori of paneer bhurji" and it logs grams, calories and protein. Pasting a Zomato order uses the listed nutrition values instead of guessing. / It's a private app for my own use, not on the App Store. / It's a personal app, so there's no sign-up.

变现:订阅制(月付,或按饮食数据库套餐收费);印度市场可考虑低价年付加 Zomato、Swiggy 订单解析增值包;也可与健身房、私教分成。

MVP:做一个 iOS 快捷指令加语音输入的小程序:先把自然语言解析成食物条目,再由代码查表算出克数和宏量营养素,先只覆盖 100 到 200 道常见印度菜并做成私有食材库;Zomato 订单截图用 OCR 直接读取营养成分,跳过估算;不做社区、不做账号系统,先卖给 20 个种子用户验证付费。

竞品:HealthifyMe、MyFitnessPal、Cronometer、MacroFactor、Cal AI

摘要:作者做了一个只给自己用的语音健身教练 App,说“两张小 roti 加一 katori paneer bhurji”就能记录克数与蛋白质,粘贴 Zomato 订单时直接读营养成分表;关键设计是 LLM 只做解析、所有计算都走代码。他用 117 条测试记录和 27 条记忆序列做评测,产品不上架、无注册,也未提任何付费。痛点真实,尤其印度饮食的记录精度问题,但需求目前只是个人验证,还需外部付费信号。
