Personal logging
Organize cycle and health logs, insights, trends, and settings in a mobile-first interface.
Healthcare / App case study
Ruby / FLOW_RUBY
An offline-first educational cycle-care prototype with pill tracking, local Dexie storage, a Capacitor mobile shell, optional single-tenant Supabase sync, and consent-controlled bring-your-own-key AI connections.
Offline-first educational health prototype
- React
- TypeScript
- Capacitor
- Dexie
- Supabase
01 / Overview
What it’s built for.
Keep core health logs usable offline while offering optional sync and consent-controlled external assistant connections.
Who it serves
People exploring personal cycle logs and pill schedules in a device-local companion.
02 / Features
Inside the app.
Pill schedules
Record taken or missed doses, inspect a recent streak, and show due or missed check-in alerts.
Optional connections
Use native bridges, configured cloud sync, or a bring-your-own-key assistant with category-level consent.
03 / Workflow
From task to outcome.
Complete onboarding and record personal logs locally.
Configure a pill schedule and record daily doses.
Review trends and informational cycle estimates.
Optionally enable configured sync or choose what context is shared with the assistant.
04 / Technical layers
How the pieces work.
React · TypeScript · Vite
Touch-oriented screens connect today’s logs, insights, trends, and settings.
Cycle engine · Dexie · IndexedDB
Core logs and tracking work on the device without a Supabase connection.
Capacitor · Native bridges
Android/iOS project shells contain notification, haptic, widget, and other platform integrations.
Supabase · BYOK AI transports
Cloud sync follows the documented single-tenant model; external AI context is consent-controlled.
05 / Limitations
What to keep in mind.
- Cycle estimates are informational, not contraception or medical advice.
- The shared sync schema requires owner-scoped authentication and RLS before public multi-user use.
- Source code and mobile shells do not establish physical-device acceptance or app-store release.
