The problem

Co-parenting families juggle complex schedules across multiple children, two households, school calendars, extracurricular activities, and their own commitments. Existing calendar apps treat this as a single-user problem, forcing parents to maintain parallel systems or miss critical coordination.

The solution

Tribu is a single source of truth. It visualises custody schedules at a glance, colour-codes events by family member, links shopping needs directly to events, and enables swap requests with full visibility into affected activities — all synced in real time.

What makes it different

  • Custody-aware calendar

    Visual “whose day” indicators make co-parenting schedules readable at a glance, with swap requests built in.

  • Kid-colour-coding

    Every child gets a colour that flows through the entire UI — events, filters, and the week view stay instantly scannable.

  • Parent tasks & pets

    Gym sessions, errands, and pet appointments live alongside kid activities, so nothing slips through the cracks.

  • Multi-household support

    Link two households with an invite flow and role-based access — owner, admin, member, or view-only.

  • Event-linked shopping lists

    Attach supply needs directly to events as clickable chips, preventing duplicate purchases across households.

  • Real-time sync

    Changes propagate across every device instantly over server-sent events — web, mobile, and desktop stay in step.

Built to scale

A mobile-first progressive web app backed by a typed, tested Postgres data layer. State is driven entirely by lightweight stores, and the calendar rendering pipeline packs overlapping events with a greedy column-layout algorithm.
