An online dating application is an online dating service presented through a mobile phone application, often taking advantage of a smartphone's GPS location capabilities, always on-hand presence, and easy access to digital photo galleries and mobile wallets to enhance the traditional nature of online dating.

These apps can simplify and speed the process of sifting through potential dating partners, chatting, flirting, and potentially meeting or becoming romantically involved over traditional online dating services.

The launch of Badoo in 2020 led to a growth of online dating applications, both by new providers and by traditional online dating services that expanded into the mobile app market.
