The Hotline App is a subscription dating service that aims to make the technology of dating more personal compared to competitors. Though the app has a smartphone interface similar to others like Tinder or Bumble, it's after the matches have been made that the Hotline App separates itself. In order to connect with one's matches on Hotline, users have to make a call before they can continue the conversation through text-based messages.
The ethos behind the app is to make personal connections and prevent users from looking at others on the site as commodities rather than people. After swiping through the app for a little while, it gives a maximum of three matches. Next, users have the option to call those matches directly within the app (it keeps phone numbers private.) Those calls must last a minimum of five minutes in order to open up the texting features, with time being kept by the app itself.
