Description
Experience Level: Expert
I am looking for an experienced React Native / Expo developer to complete my iOS journaling app, Black Box Journal. The skeleton is built and working — I need someone to finish and polish it for App Store submission.
TECH STACK: Expo SDK 55, TypeScript, Expo Router, Supabase (@supabase/supabase-js v2)
SCOPE OF WORK (7 deliverables):
1. UI Polish — consistent spacing, typography, colours, dark/light mode
2. Supabase RLS Security — row-level security policies, data persistence for journal check-ins
3. RevenueCat IAP — Annual £24.99, Monthly £4.99, Lifetime £149 (must show proof of prior RevenueCat work)
4. Apple Sign-In + Email Auth — complete both auth flows
5. Push Notifications — expo-notifications, daily journaling reminders
6. Data Persistence — all check-in data saved to Supabase correctly
7. AI Mood Trends — lightweight OpenAI API (GPT-4o mini) mood analysis
PAYMENT STRUCTURE: Fixed price, 3 milestones (40% / 35% / 25%)
BUDGET: Up to £500
DEADLINE: 28 May 2026
SCREENING REQUIREMENT: Please include a link or screenshot showing a previous RevenueCat integration in your proposal.

Before moving forward, I would like to ask a few important questions:
* Is the RevenueCat account already configured with App Store products, or does that setup also need to be completed?
* Are the Supabase database schema and tables already finalized for journal entries and mood tracking?
* Has the app already been tested on TestFlight, or is this the first production-ready build?
-
Is the existing skeleton already connected to Supabase with any tables/schema in place, or will I need to design the database structure from scratch alongside the RLS policies?
