Tinder wants you to know that Tinder isnt just for hooking up. A big update to the companys iOS and Android app today lets you share moments, photos that expire after 24 hours, with everyone youve ever matched with. Founder Sean Rad tells TechCrunch that he hopes the new feature will amplify the less flirty behaviors hes seeing in the app. Tinder is also for finding advice in a new city, making new friends, and checking in with matches you might not have liked on the first time around, Rad says.
