    I have an Android and iOS app that tracks an user steps with Google Fit / Apple Health API, and it rewards the user with a coin based on the number of steps the user has gotten. It also uses a backend simple program to get and publish certain data to the app. I need to add functionality to both apps (the Android and the iOS version). I need to add an option to pick a sport (from a list that the app should show), and let the user start and stop a timer. When the user stops the timer, and based on the sport the user had chosen, it will give him a number of coins. Please, have in mind that this is a very simple project, and I'll have an appropriate maximum budget.

    I want to integrate into my system a webscraper interface, whereby my customers determine what to scrape (usually their own website). They don't need to be running scrapes or seeing the data, but they should set up 'what to scrape', and then we take it from there. If you have suggestions or white label software i'm also open to that. Hope that makes sense! Thanks.
