Default NFC Proximity app for Galaxy S4 i9500

Hello,

Just went thru this link http://forum.xda-developers.com/show...32&postcount=1 and it seems like a neat idea to me.

Wanted to know that has anybody worked on , or such an app already available for Galaxy S4 i9500. Would love to try it with the NTAG203s I have.

Requested please to port it if not already available.

Thanks.
