Handle - Consumer App
Budget: $5,000 – $10,000 USD
Handle — App Developer Brief
Handle is a social emotional intelligence platform that helps users train their communication skills through daily gamified scenarios, get real-time AI assistance in difficult conversations, and engage with a community of like-minded people.
Think of it as a gym for your social and emotional intelligence — you train daily, level up over time, and get real help when you need it most.
Core Modules
1. Arena — Daily Training
The main engagement loop. Users receive AI-generated scenarios representing real-life difficult situations and must craft the best possible response. An AI judge scores each response based on empathy, clarity, assertiveness, and effectiveness.
Key features:
∙ Infinite scroll feed of scenarios
∙ Categories: Business, Dating, Family, Social, Fitness/Competition
∙ Difficulty levels: Normal, Hard, Legendary (rare, random)
∙ Daily streak system with push notifications
∙ Weekly leaderboard per category
∙ Score history and progress tracking
∙ Share score/response to TikTok/Instagram natively
2. Shield — Real-Time AI Help
When users face a real difficult situation, they describe the context and receive 3 tailored response options generated by AI — assertive, diplomatic, or neutral.
Key features:
∙ Context input — who, what they said, relationship type
∙ 3 AI-generated response variants
∙ Response style selector
∙ Save responses for future reference
∙ 3 free uses per day, unlimited on paid plan
∙ Powered by Claude or GPT-4 API with RAG on communication psychology books and courses
3. Feed — Community
A scrollable feed where users share their Arena responses and scores. Others can like, comment, and save responses. Best responses surface to the top.
Key features:
∙ Chronological and ranked feed
∙ Like, comment, save functionality
∙ Filter by category
∙ Share to external social media
∙ Report/moderation system
Gamification & Retention Mechanics
These are critical — they are the core retention engine of the app:
Streak system — daily login and scenario completion maintains streak. Missing a day resets it. Push notification 1 hour before midnight if streak not completed.
Variable rewards — 70% normal scenarios, 20% hard scenarios with bonus points, 8% rare scenarios with large reward, 2% legendary scenarios with maximum reward and special badge.
Level progression — Bronze → Silver → Gold → Platinum → Diamond → Legend. Each level unlocks new scenario categories and profile customization.
Weekly challenges — complete 5 Business scenarios this week, achieve 3 scores above 80, etc.
Friend challenges — send a specific scenario to a friend directly via WhatsApp or iMessage with a challenge link.
Profile stats — total scenarios completed, average score per category, best score, current streak, rank among friends.
Self-Learning AI System
Every user response in Arena is stored and tagged with its score. High-scoring responses become positive training examples. Low-scoring responses become negative examples. Over time, the AI scoring system improves based on real user data — creating a proprietary dataset of human responses to difficult social situations that no competitor can replicate.
Tech Stack Requirements
Frontend: React Native — mandatory for iOS and Android from a single codebase
Backend: Node.js or Python (FastAPI preferred)
Database: PostgreSQL for user data, scores, responses
Vector Database: Pinecone or Weaviate for RAG implementation on Shield
AI Integration: Claude API or OpenAI GPT-4 API
Auth: Supabase Auth or Firebase Auth
Payments: RevenueCat
Push Notifications: OneSignal
Analytics: Mixpanel or Amplitude
Storage: AWS S3 for any media
Hosting: AWS or Google Cloud — must be scalable architecture from day one
Scale Requirements
Architecture must support scaling from 1,000 to 200,000+ active users without full rewrite. Clean, modular code with clear documentation. API-first approach.
What We’re Looking For
∙ Strong React Native experience with published apps
∙ Experience with AI API integration (OpenAI or Anthropic)
∙ Clean code, well documented
∙ Portfolio of previous mobile apps required
