Harmony

Most habit trackers run on shame. A streak you can break, a plant that dies if you skip a day, a score that goes down. Harmony has none of that — no streaks, no shame, no plant pets, no score. The premise is the opposite: your habits are how you return to yourself, and one missed day should never read as failure.

The Bloom

The centre of the app is a soft radial visual called the Bloom — your week as a living flower, one petal per area of life. A petal grows as you tend that area and eases back when it goes untended. It reads a rolling two-week window, recalculated daily, so a single missed day barely moves it.

Two things shape a petal: how much the area matters to you (lower-stakes areas fill more readily, which pulls the eye toward the things you said matter most) and how each habit inside it is doing, weighted the way you choose. There are also Tugs — negative habits you want to ease off. They’re never scheduled; you just note them on the days they happen and they gently pull an area back, so a week honestly shows both the lift and the drag.

Under the hood

Harmony is a PWA: React + TypeScript on Vite, with Dexie (IndexedDB) as the source of truth on each device. Writes mirror to Supabase and, when offline, queue in a durable outbox that flushes on reconnect; live changes arrive over Supabase Realtime with focus/online/poll backstops and an authoritative pull on sign-in. Push notifications land within about a minute of the time you set, delivered by a separate Cloudflare Worker that signs VAPID + aes128gcm payloads with the Web Crypto API — no Node crypto dependency at all.

The one decision I’d defend hardest is keeping the scheduling and “drift” engine single-sourced in a shared package, re-exported as thin shims into both the web app and the push worker. The rule that decides whether a habit is due today has to be byte-identical in both places, or reminders quietly fire on the wrong days. Duplicating it would have been faster to write and a nightmare to trust.

Retrospective to backfill: the honest account of what the drift model got wrong before it settled — this is the interesting part and only I can write it truthfully.
