feat(kairos): Kairos — personal life manager (iOS)

A native Apple app that brings time, money and habits into a single engine, able to answer “can I spend 30,000 on Saturday night?” from real balances, envelopes, due dates and goals.

Context

Budget apps count money, calendars count time, trackers count habits — none of them reason about all three at once. Kairos starts from a concrete question: can I afford this, given everything else?

What I did

A personal product, designed then built milestone by milestone:

Decision engine: four analyses (balances, envelopes, due dates, goals) combined into a weighted score, under two non-negotiable caps.
Money: envelopes, income split by percentage keys, savings kept apart from spendable money.
Time: tasks and habits to create, reschedule and keep, a “Today” screen and notifications.
Apple integration: SwiftData locally, CloudKit sync, calendar through EventKit, App Intents and iPhone and iPad widgets.
Generated design system: a single set of tokens (JSON, Swift, TS) and eighteen components, with snapshots of all four theme combinations and six CI guards.
A monorepo ready for Android and a backend: rules aren't shared across platforms, but their expected outputs are, which makes parity testable.
