Mobile App Dev + Backend

THERAWORLD – Mobile App Developer (iOS/Android) + Backend (AI Voice / Real-time / Production)

I'm building THERAWORLD, a premium emotional wellness app (not a basic utility app).

This needs to feel cinematic, calm, premium, and polished — with strong UX flow, voice interaction, and scalable backend architecture.

I am looking for a developer (individual or small team) who can handle:

• Mobile app development (iOS + Android)
• Backend/API integration
• AI/voice integration (real-time or near real-time)
• Production-ready builds (not prototype-only)
• Weekly sprint workflow

What THERAWORLD includes (Phase 0 MVP)

• User onboarding + personalization
• Guided support flows (emotional wellness sessions)
• Voice/audio experience (speak + listen)
• Personalized recommendations / session logic
• Basic progress tools (check-ins / routines / journaling)
• Clean premium UI and smooth transitions
• Scalable backend foundation for future features

Important

This is a premium experience product.

I am not looking for a basic app clone or generic "Calm-style" screens.

I need someone who understands:

• UX polish
• animation/micro-interactions
• latency and real-time voice behavior
• clean architecture for future scale
• how to ship production apps

Required workflow (must agree)

• Weekly fixed-scope sprints
• End-of-sprint demo
• Payment after sprint acceptance
• Code committed to my GitHub repo from day 1
• TestFlight + Android APK builds during development

To apply, answer these 4 questions clearly (required)

1) Shipped app proof (most important)

Send 3 live mobile apps (App Store / Google Play) you personally worked on and confirm your exact role on each:

• UI/UX
• iOS
• Android
• Backend
• QA/testing
• Store release

2) Voice / AI experience (real work only)

Have you built a real-time AI voice feature inside a mobile app (not just text chat)?

If yes, explain briefly:

• Push-to-talk or live streaming?
• Tools/services used (OpenAI, ElevenLabs, WebRTC, LiveKit, etc.)
• What part you personally built

3) Premium UI quality proof

THERAWORLD needs a cinematic, calm luxury feel with polished flow.

Share 2 examples (apps/screens) that show:

• premium UI quality
• polished animations/micro-interactions

4) Sprint + code ownership confirmation

Can you work with:

• weekly fixed-scope sprints
• demo at end of sprint
• payment after acceptance
• code in my GitHub repo from day 1

Please confirm yes/no and any notes.

Bonus (not required, but helps)

• Experience in wellness / coaching / mental health / habit apps
• Experience with audio/streaming performance and latency optimization
• Experience designing or implementing premium motion systems
• Experience with Firebase / Supabase / AWS

Notes

Please keep your response direct and specific.

I will prioritize people who show real shipped proof, clear technical thinking, and a professional workflow.
