Hinted LLC is creating a mobile app that allows users to make personalized online wish lists and gift registries at local shops, addressing frustrations with traditional gift registries. Survey results show 88% of respondents are likely to use the app, with a target initial focus on wedding registries, which represent a $19 billion annual market in the U.S. The app is set to launch its beta version in Washington, D.C. in January 2014, with plans for revenue generation through transaction fees and a significant market expansion in 2015.
