Not safe for kids under 18
OkCupid is a dating app where users can upload and browse profile pictures and bio descriptions. If two users “match”, they can directly message one another. An introductory message can be sent even if the other user has not reciprocated a liked profile. Sexual/Mature content is likely.

In-depth breakdown

Minimum Age Requirement
Messaging Capabillities
After users “match” by both approving of the others’ profile/bio, they can send direct messages.
Location Sharing
Location is used to connect users within a certain radius and cannot be turned off while using the app.
Parental Controls
None, though Apple and Android parental controls could be used at the device level.
OkCupid markets itself as unique by having users answer questions to help filter who they connect with (as opposed to users choosing who they connect with based off of a few pictures). It also bans profiles for nudity/explicit content. Has an incognito mode so your profile is not viewed. Owned by The Match Group (Like Tinder,Hinge, and Match).
