iOS App (React + Capacitor + Supabase) — Fix Screen Time, Sync & Subscription Bugs

We have a live iOS app for families/parental control, built with React + TypeScript + Capacitor, backed by Supabase (Postgres + Realtime), distributed via TestFlight. Core flows work but are unreliable. We need an experienced mobile dev to fix the issues below and harden the weak areas so they stop recurring. Tech stack: - React + TypeScript (Capacitor wrapping a web app into native iOS) - Native iOS / Swift for Apple Screen Time (Family Controls / DeviceActivity) - Supabase: Postgres, Auth, Realtime - Subscriptions / paywall (in-app purchase entitlements) - TestFlight / App Store Connect What needs fixing & stabilizing: 1. Screen Time reliability — limits/blocking sometimes don't fire when they should. Need it to enforce consistently on device. 2. Subscriptions — the app sometimes prompts users to upgrade to Pro when they're already Pro (entitlement/subscription state is read incorrectly). 3. Signup & onboarding — account creation and parent-child linking are unreliable/confusing. 4. Data sync — tasks, parent dashboard, and realtime updates go stale or missing. For each: fix the root cause and stabilize the surrounding code against regressions. Engagement: Fixed-price, ~$1,000 total, split into milestones (Screen Time + subscriptions are the priorities). Full GitHub repo and a dev/TestFlight build provided to the selected candidate after vetting. Required experience: - Capacitor + React in production iOS apps - Native iOS / Swift, specifically Apple Family Controls / Screen Time APIs (this is essential — please confirm) - Supabase or similar Postgres + realtime backends - In-app purchase / subscription entitlement handling - Debugging on real devices and shipping via TestFlight To apply: Briefly describe (1) your experience with Apple's Screen Time / Family Controls framework, and (2) a subscription-entitlement bug you've fixed. Generic applications will be ignored.
