App development for a app that works similar to Instagram

Outfit challenge Uploade picture of your outfit of the day and let you decide what category it belongs under. The category can be “party, sporty, high fashion, hipster, casual, beach, preppy etc” The picture will then be automaticly matched with another picture in the same category. Other users can then vote for what kind of outfit they like the most. When a user have voted between to pictures the pictures are separated again and matched with other pictures in the same category for a new round of voting for other users. After the user has voted on the picture a little symbol will come up on top of the pictures that shows how many positive og negative votes the picture has got. If the picture looses X times in a row the picture is out of the competition. Users have their own “homepage” like the one on instagram (Same layout / design template) Instead of seeing how many “likes” each picture has you can see how many wins they have. Users also have to have the opportunity to challenge friends in a fashion battle. By selecting a friend you can invite them to battle you in a specific category. For example “first one to get 100 likes in the “high fashion” category when the pictures are competing against each other “picture vs picture” Here you can see followers and battles won Its also has to be possible to see top lists of pictures that has the most number of wins in each category and the highest % number of wins in each category.
