Ultra Beam

This app can prove to be a replacement of NFC in non-NFC devices. It will enable you to send links, text, contacts, etc at a superfast speed by using ultrasound(which you cannot hear) from your mobile's speakers.
It requires No Internet, No Wi-Fi, No Bluetooth, only ultrasound.

Features
1.) Send contacts, text, youtube, play music and all other links within seconds.
2.) No pairing required. Its unique technology allows to send messages just by keeping the devices near and pressing the 'Beam' button.
3.) Send to more than one nearby devices at once.
4.) You can also use it in flight mode.
5.) Now you can send messages in any language or even emoji's(Non-English characters take double the normal time to send messages).

How To Use

1.) Open the app on both the devices, type the message and press 'Beam' button(this will broadcast the messages to all nearby(2-3 metres) devices).
2.) To send links or contacts ,just open the browser or contacts app, click share and chose UltraBeam after which message will be sent automatically.

So what are you waiting for! Just download this innovate app to share music, videos, movies(links) in no time...
Happy Beaming!!

Note:- Playing high frequency sounds does not and can NOT damage your speakers. It is equivalent to playing normal music(but you cant hear ultrasound).

This app is in Beta(development stage). As a result ,the app may have many bugs. I will soon resolve them in subsequent updates, however the process can be made faster with your cooperation. Therefore it will be highly appreciated if you send your valuable feedback which will help me improve this app.
Happy Beaming!
