Experienced iOS Developer Needed to Build a Wellness & Habit-Building App

I'm looking for a skilled iOS developer to build the App of a consumer wellness app in the sleep, focus, and habit-building space. About the project (high level): The app helps users build healthier daily routines using behavioral psychology, gamification (streaks, scores, badges), and positive reinforcement — all while working within Apple's platform rules (no jailbreak tricks, no fighting the OS). It combines elements of sleep routines, smart alarms, screen-time awareness, and an AI-powered coaching experience into one product. Full product details, wireframes, and feature specs will be shared after signing an NDA. This post intentionally describes the concept only at a high level. App scope (approximate): Bedtime routine flow with scheduled reminders, calming audio playback, and simple in-app sleep tracking Challenge-based alarm system (puzzles, motion tasks, QR scan, etc.) to stop the alarm Screen Time integration to monitor selected apps and daily usage limits, with an "earn more time" activity flow Daily AI-generated insights/coaching messages (via a third-party LLM API) Gamification layer: streaks, points, scores, and badges Subscription with dynamic pricing logic (via App Store in-app purchases) Clean, modern, calming UI Timeline: 3–6 weeks for full App Budget: $1,500 Required Skills & Tech Stack Swift & SwiftUI — native iOS development (this must be a native app, not cross-platform) Screen Time API — FamilyControls, ManagedSettings, and DeviceActivity frameworks (critical; please confirm hands-on experience) UserNotifications — scheduled and rich local notifications AVFoundation / background audio — audio playback for sleep sounds and alarms, including background modes Core Motion / pedometer — motion-based challenges (shake detection, step counting) StoreKit 2 — auto-renewing subscriptions, promotional offers, and discount/offer codes HealthKit (nice to have) — sleep data integration REST API integration — connecting to an LLM API (e.g., Claude or OpenAI) for coaching messages Backend — Firebase or Supabase (auth, database, analytics); propose what you'd use and why App Store submission experience — you've shipped apps that passed review, ideally ones using Screen Time or subscription entitlements. Ideal Candidate Has shipped at least 2–3 consumer iOS apps to the App Store Has specific experience with the Screen Time API or alarm/sleep apps (huge plus) Communicates clearly in English and provides weekly progress updates Comfortable working with a non-technical founder — you'll help translate product ideas into technical decisions Willing to sign an NDA before receiving full specifications How to Apply Please include: Links to 2–3 iOS apps you've built (App Store links preferred) A short note on your experience with the Screen Time API and StoreKit subscriptions specifically Your estimated timeline and cost for an App of this scope Your availability over the next 3 months
