I understand what you mean by dating app based on events. I also understand that which features I need to add so that the app will be become a complementary with a perfect dating event based app. Hence I am suggesting to add " Facebook Find Friends Nearby" feature with your app since the main concern regarding a dating app are 'find nearby friends' and 'verification method'.
Facebook’s web and mobile apps have a new feature called “Find Friends Nearby” that, as the name suggests, lets you find friends and potential friends based on their proximity to your current location. For verification method in this app we will add 2/3-step ID verification that makes sure that you are connecting to the real & right person. The method should contain proper verification of the user’s id proof such that it ensures no fake profiles.
Specifications:
Users would be able to register via only Facebook
Users would be shown with their nearby matches on the application.
For a selected match, they can view their complete profile
Can send them an interest, wink at them or can initiate a private chat with the user
User can also add other users to their favorites list to browse later
They will also be provided with certain filters to view the other profiles in the app based on name, age, country, etc.
Invite their friends to the app and can publicly share their information on their profile, which can be viewed by any user of the app
Pls clarify all and pardon me if I am wrong.
