PocketMoney

PocketMoney started as a problem in my own house: keeping track of my daughter's allowance, and wanting a way to actually teach her about money instead of just handing it over. So I built her an app — a mobile-first, bilingual family allowance ledger. It is pure virtual tracking: no banking, no real money. I log her allowance with a reason, she sees her balance and savings progress on her own device via a QR code, and nobody has to remember what was promised.

As much as it is a tracker, it is a teaching tool. I use it to show her how saving toward a goal works, what interest does to money over time, and why a plan beats an impulse — the small financial intuitions I wish someone had drawn out for me early. It turns abstract ideas into something she can watch grow.

Under the hood it is React Native (Expo) on Supabase — Postgres with row-level security, Edge Functions, and realtime sync — with RevenueCat for subscriptions, PostHog for analytics, and a Next.js web dashboard. Privacy is a hard line: a child profile stores only a display name and an emoji avatar; no birthdate, no email, nothing COPPA-governed.

And it runs on the full spec-first system I write about — a locked PRD, a Kanban board, defined roles, and a rule that nothing gets built before the intent is written down. It is the clearest day-to-day proof that, in the AI era, the discipline upstream is what makes the execution downstream worth anything.
