Project description:
"Phase 1 is a lean but future-proof MVP for a patent-pending acoustic app on iOS and Android. A full technical brief already exists and will be provided after an executed NDA; this posting only defines the outer boundaries of the MVP.
Core MVP Scope
• Account Flow — email-based registration and login
• Audio Engine — compute a proprietary base tone (details post-NDA), display a tone ladder, and play pure synthesized sine waves with tap-to-play and loop playback without audible latency or artifacts
• Performance — all audio must run in real time with efficient DSP and clean threading
Architecture Requirements
The codebase must be structured to allow later additions — new screens, a second computation mode using astrological inputs, and an optional ambient-audio layer — without major refactoring or rewrite. MVP is a single-screen experience, but must sit within a proper navigation stack from day one.
Design Direction
The interface should be intuitive and minimal: a clean home screen and one-tap access to the tone ladder. I will provide rough wireframes after NDA and welcome UI polish and motion suggestions.
Tech & Delivery Notes
• Native or well-supported cross-platform solutions are acceptable so long as audio timing remains precise
• Clean architecture, modular components, and DI patterns will be reviewed at code handover
• Git with meaningful commits and short milestone cycles is expected
Deliverables
Compilable iOS & Android repositories
TestFlight build + internal APK for review
Brief setup notes and high-level architecture diagram
Once the milestones are agreed upon, I will provide the complete technical brief so you can finalize timeline and cost." (client-provided description)
