Elderly-friendly recurring task & medication reminder tracker — big type, high contrast, offline-first PWA.
Ritim is a reminder tracker designed for elderly users: medications, habits and recurring chores, all waiting in the same place every day. Big type, high contrast and a single-screen flow make it usable without tech help. It is an offline-first PWA — it keeps working without a network — with an optional self-hostable sync server (Node.js + Express + better-sqlite3) for multi-device households. The whole project is vibe-coded: the author describes what they want in plain Turkish, and Anthropic's Claude, working in Claude Code, writes all the code, the visual design and the README. The author tests each version on their own phone and asks for changes — no code written or reviewed line by line by hand. A rare, honest documented case of a non-programmer shipping a real product with AI. Note: the project is small and new (2 GitHub stars) — presented as an indie experiment, not a mature product.
