Match making by your common interests.
In short: You take the first step of choosing your better half by matching your internet history with others' because your internet history and the apps you use can define you better than yourself if not the best.
You access internet unknowingly and genuine unbiased data is stored by your devices. If you have never used this internet usage pattern ever then this is the best possible way to use it.
Because when you chat or meet someone you will always get filtered data from that person and the same goes for you. Sometimes one may go even farther by telling lies in order to impress him/her.
Long explanation :
I think most of the services available are based upon mutual acceptance of how one's better half will look and how fair is he/she when you talk, chat or may even meet multiple times.
Based on your overall experience you might decide whether you should spend your life with that person.
I think you have to take such an important life's decision just on the recent data that you have generated in you mind (or simply an image of that person).
However I feel like you can hardly describe yourself (means your likes and dislikes) in few weeks to even months of togetherness.
Problem surfaces when you start knowing some more likes and dislikes about that person, which you do not like and can ignore.
If you share your genuine browsing data then patterns can be generated out it to match with others'.
I'm building the MVP. But it is better to share the idea and ask you whether you will try it or not.
