I need an iPhone/iPad app. I already have a design for it, I just need it to be built. I am a serial entrepreneur who has successfully launched 3 software tools. - 2 apps and a chrome plugin. We are looking for an engineer for this project. This project is a mesh bluetooth application. Devices with the app can be recognized by each other. A "master" device connects to slave devices to use their speakers (with permission). The slave devices then play whatever sound the master device emits, in sync. The devices appear in a list and the "master" device control can be transferred to any device in the list (with approvals). In other words, this makes multiple iPhones/iPads operate as a speaker network to listen to music or conference calls/videos/movies/etc in the absence of an external bluetooth speaker.
