A Better Life
A small set of free web tools that help you tune sleep, habits, and focus. Everything runs in the browser — no signup, no account.
A Better Life
Overview
A Better Life is a website with small tools and guides for tuning everyday life. Phase 1 ships three tools — Sleep Calculator, Bedtime Calculator, and Evening Routine Builder — wired so that a search visit can flow naturally from one tool to the next and into a routine.
The problem
There is no shortage of articles about sleep and evening routines, but few of them let you try something on the spot and keep the result. The gap shows up as poor retention and routines that never form.
Key features
- Sleep Calculator: works back from a wake-up time to the right bedtime
- Bedtime Calculator: from a bedtime to wake-up windows aligned with sleep cycles
- Evening Routine Builder: assemble a routine that fits your own rhythm
- Results live in localStorage — no signup, no server-side state
- Bilingual (ja / en) blog provides context around the tools
Tech stack
Architecture
Built with Next.js 15 (App Router) and TypeScript, statically exported with `output: "export"` and deployed to Cloudflare Pages. Phase 1 holds no server state — every calculation and article either lives in localStorage or is baked at build time.
How AI is used
No AI inside the product yet. AI is used in the production pipeline — drafting articles, designing keywords, and reviewing bilingual copy.
Evaluation & Operations
GA4 tracks tool usage and intra-site navigation, watching whether the intended search → tool → adjacent-tool flow actually happens. Articles are placed to feel like a natural next step after using a tool.
