Snapchat, the social service that bases its model on disappearing messages, updated its app this week to provide the option of making messages reappear. The update also includes new photo lenses and trophies for completing tasks. “Snapchat began letting U.S. users replay three messages for 99 cents, the first time the company has charged for any feature in the free program,” The Wall Street Journal reports. “With more than 100 million users logging on to Snapchat every day, those cents could begin to add up.” The move could also prove beneficial to Apple, since the company typically receives 30 percent of in-app purchases.
