I am looking for a IOS app developer for waste sorting . It is a very simple app where 6 types of bins will be there and when someone drags and drops from a list of waste it gives a score. Also any new types of waste has to gone into a special bin for later sorting . Overall it should provide a score for correct sorting. There will be approximately 200 pictures to be sorted in 6 varieties of bins .
