2 links in one - depending on the user's device, it directs to the right one. How?

Question

Programming

The user sees a banner in the mobile version, clicks on it and follows the link corresponding to his device. If I went to iPhones, then to the app store. If from an android device, then in the Google market, for example.
What services exist? Google does not help in solving the problem.
Or how to solve it on your own?
Thank you.
