Installed App Detection: how can i scan and list phones in the vicinity based on apps installed

Question

am building an app which intends to connect, using wifi direct, with users who have this particular app installed on their phones as well. I would like to know how this app installed in my phone would be able to only scan for devices with this particular app installed.

Basically I would like to filter out the phones in the vicinity (wrt wifi range) and display only those with this particular app installed.

Thanks!
