Hey James, I am building that helps parents focus on their kids long term goals. Parents don’t have to be fluent on any skills to teach kids. All they have to do is choose the goal like chess, swimming, trachtenberg math, yoga etc and you get weekly list.

做了个狗龄计算器,才发现"1 狗年 = 7 人年"是错的 家里养了只金毛,一直按"狗 1 岁 = 人 7 岁"算,后来查资料发现这个公式根本不科学——狗的第一年其实相当于人的 15 岁左右,而且不同体型的狗衰老速度差很远。 于是做了个工具:dogyearcalc.com ( https://dogyearcalc.com/) 它做了什么: - 内置 4 种计算公式:AKC 体型公式、UC Davis 表观遗传时钟(测 DNA 甲基化得出的)、Standard 方法、以及那个不科学的 Classic 7x 方法(留着做对比) - 支持 386+ 犬种的品种特异性计算,大型犬和小型犬的衰老曲线完全不同 - 多狗对比模式——家里养了两只以上的可以并排看 - 生命阶段可视化 + 当前阶段的健康建议 - 8 种语言(中英日韩德西法葡) 技术方面: 纯静态站,HTML + CSS + 原生 JS ,部署在 Cloudflare Pages 。没有框架,没有注册,加载速度 89ms 。计算全部前端完成,不收集任何数据。 想听听大家的意见: 1.
