In the AI era, it is no longer so difficult to finance things from your own resources bootstrapped (except for promotion or hardware-intensive solutions).
I have always saved money and tried to do things myself (what I didn't know, I learned to do to save on financial costs).
WhisperLink is an iOS app built for real world noisy environments like cafés, bars, concerts, airports and crowded streets.
Instead of trying to fight background noise, it lets two people hear each other directly through headphones with very low latency audio.
It also includes a local Bluetooth/WiFi mode for nearby communication without internet, plus a simple nearby emergency mesh chat feature.
