iOS/Android Bid Button backend development


I need to develop a an auction/eBay-like bid button in my iOS and Android app. The rest of the app is already developed. So is the server based API.

My developer could not program this part so that is why I am posting it on Freelancer.

The price of the item for sale has to be updated live in the app for all users in real time.


User presses Bid button.

Price of the item will raise with $1

All users will see the change in the price live in the app.

Thank you
