Buy Android Voice Chat App

I’d like to acquire a complete, production-ready Android voice chat application. My priority is group voice chat, and the build must already include admin controls (e.g., the ability to mute, remove, or otherwise manage participants within a room).

If you have a stable solution on hand, please share:
• a short demo video or APK so I can test real-time audio quality and latency
• a brief feature list confirming group chat and admin management
• the tech stack you used (native Android, Flutter, React Native, etc.) and any third-party services or SDKs it depends on

I’m not looking to fund new development; I want to licence or purchase an existing app with full source code and the rights to rebrand and distribute it. Documentation for build, deployment, and basic maintenance should be included so I can integrate it quickly into my ecosystem.

Once I verify the demo and code quality, we can finalise hand-over and payment in one straightforward milestone.
