Radon - Share using Ultrasound

Changes 1.1c : Minor improvements

APK Description:

WHY BEAM TO ONE PERSON AT A TIME?
Skip QR codes or NFC, Radon lets you share to everyone nearby, as long as you have the app open. As soon as they open Radon on their device, they'll automatically open whatever you shared, on as many devices as you want.

WHY FUMBLE WITH CODES AND PAIRING?
Radon uses your sensors to broadcast links, so you don't need to pair or tap. As long as the other device is nearby, Radon just works.

NO NFC? NO PROBLEM.
Radon uses sensors you already have, and everyone else has including Wi-Fi, Bluetooth and Ultrasound. It does everything automatically, so all you have to do is tap share.
