Using it's proprietary technology, Dil Mil shows you potential matches to like or pass. Similarly, your profile is shown as a potential match to other users to like or pass. If two users like each other's profiles, they are matched and hence, are able to chat on the app.
All the heavy-lifting is done by Dil Mil. All you need to do as a user is, go through the single click sign on process and fill in 5 quick details (height, community, religion, education & career) to complete your Dil Mil profile. Once your profile is complete, you will be shown potential matches on the app and you can narrow down your preferences by selecting potential match filters to see specific types of potential matches if you like.
