Dating app

Looking to develop a dating app targeting groups of society members living in similar foreign land areas. The niche objective is make sure people from the same country who have migrated to different foreign lands link up depending on proximity from each other. For example single nigerians living in london can easily find others near them and link up. The application should also allow group videos so that members may invite other members from their home country to group calls and share experiences in the new different societies they are staying and possibly create connections.
