Startup Idea : Spark

I have an idea to create an app that allow people from all over the world to meet each other or maybe more. the app connects to Facebook, Twitter and Instragram. Users can upload pictures and create a mini bio, what they are looking for in there perfect man/woman or there idea of a perfect Date. users who are also searching can search by name or just filter there preferences such as age, cast, height, religion and so on. Users can chat and send/receive messages and images. if you like a person and they like you back you get notified otherwise it was just not meant to be. you can also make your like public or private. also users can block each other. The Idea behind this is to make it a simple easy to use app for all the single people in the world. Originally this idea was tailored to be similar to Single Muslims.com but an app. Again this could be a website or an app or both. Please let me know what you think and if you are interested in this idea.
