WASHINGTON POST – Nov 28 – Hinge is the latest dating app to add time limits; after a match, users have 24h to start a conversation or the match disappears. If they start chatting, they have 14 days before their conversation vanishes. Bumble also puts a 24h limit on matches; JSwipe matches disappear after 18 days if no one says hello. “Time limits give users that extra momentum to meet up in person,” thinks Eli Finkel, a social psychologist. Hinge saw a 70% increase in chats started, and a 50% in how often matches exchanged phone numbers.
