Baby Tracker

A shared baby tracking PWA for logging sleep, feeds, nappies, and pumping sessions.

I originally used Jeeves (my AI assistant) to help manage baby tracking through conversational commands. It worked well, but I wanted something with a dedicated UI that I could share with my wife and iterate on independently from the assistant itself.

Built so two parents can track everything from their phones with no accounts — just a shared PIN.

Features

• Sleep — start/pause/resume/stop timer, duration tracking
• Feeds — breast (timer with left/right side), formula (ml), expressed (ml)
• Nappies — one-tap logging: wet, dirty, or both
• Pump — timer with amount (ml) on stop
• Daily Tasks — recurring to-dos with configurable frequency and start dates
• Dashboard — time-since cards, active timers visible to both users, quick-add sheet
• History — daily timeline, weekly summary stats

Architecture

Client

React + Redux Toolkit + React Router SPA with an iOS-inspired design system (Tailwind CSS).

• UI and routes in src/
• API client in src/lib/api.ts

API

Cloudflare Workers + Hono + D1 SQLite with layered architecture and manual dependency injection:

• Routes: worker/routes/ (HTTP handlers, Zod validation)
• Use cases: worker/usecases/ (business logic)
• Repositories: worker/repositories/ (interface + D1 implementations)
• Timer logic: worker/utils/timer.ts (elapsed time with pause support)

Timer state is server-authoritative — both users see active timers via dashboard polling.
