Hater is a mobile dating app developed for iOS devices, available on the App Store. If you?re new to online dating or are tired of Tinder, Bumble and the many others on the market today, Hater offers a new twist on the classic dating app. Instead of matching with a potential partner based on things you love, Hater takes things in the opposite direction. Match up with guys or girls based on the things you both hate and you?ll never run out of things to complain about together.
