iPhone apps

Hello, I would like to know who can make a app for the watch, I bought the brand new watch, it allows the Uber app on the watch but not the Lyft app, I live in a area that has no UbersI would really like to have the Lyft app, this is a serious question, please let me know, I don’t like carrying my phone all the time when I go out, that’s why I bought the watch.
