Job Title: Flutter Developer for Card Game Mastery App (Mastermind Poker & Blackjack) Budget: $1,500 – $2,000 Project Type: MVP (Minimum Viable Product) Platforms: iOS & Android (Cross-platform) Overview: I am seeking a developer to build "Mastermind Poker & Blackjack," an educational trainer app. The app helps users master game theory and mathematical strategy through interactive "tests" and real-time AI feedback. This is NOT a gambling app. No real money is used. It is a logic-based training tool. Key Deliverables: 1. Blackjack Training Module: - A gameplay simulator where the app compares user decisions (Hit, Stand, Double, Split) against a provided Basic Strategy JSON matrix. • Immediate visual feedback (e.g., a "Red Flash" or "Leak Warning") when the user deviates from the math. 2. Poker Pre-Flop Trainer: - A drill-based interface showing 2-card hands and table positions. • Users must decide to "Raise" or "Fold" based on GTO (Game Theory Optimal) charts. 3. Mastery Testing System: - Logic to track "Streaks" (e.g., "Pass 25 hands perfectly to unlock the next level"). 4. Subscription Implementation (Crucial): • Integration with RevenueCat to manage three tiers: • Weekly: $4.99 (Must include 7-Day Free Trial) • Monthly: $12.00 • Yearly: $135.00 • Must include a "Cancel Anytime" button in the user profile that links to App Store/Google Play settings. Technical Stack Requirements: • Frontend: Flutter (preferred) or FlutterFlow. • Backend: Firebase (for user progress, streaks, and ranks). • Payment API: RevenueCat for robust subscription management. • UI Style: Dark mode, high-tech, professional "Mastermind" aesthetic. Application Requirements: • Please provide examples of apps you have built with recurring subscriptions. • Explain how you will handle the "7-day free trial" logic on a weekly subscription. • Confirm you can work within the $1,500 - $2,000 budget for this MVP.
