My posts got deleted on almost every social platform I used. There's hardly pure speech freedom anywhere.
This app would at least allow the possibility of your voice to be heard by those who want to listen, no matter how it sounds or how little the chance is. No wifi or internet needed, just pure bluetooth. There's no plan to use any encryption, as those who dare to speak out won't mind being found.
I did some tests with the current prototype and it works within at least 30 feet in the house, with walls in between. Hope it works better in open spaces. Yet to try other scenarios like when cars are waiting at traffic lights, passing each other, or in one moving vehicle, train or even plane.
Please see the test document, with hand-written Chinese design draft.
