West Coasters are always in danger of seeing spoilers of their favorite TV shows on Twitter, but a new app, Twivo, allows you to block tweets about your favorite shows until you're ready to watch them.
What's even more of a revelation is the app's developer: 17-year-old Jen Lamere of Nashua, NH.
Lamere recently won a Boston hackathon that she entered with Twivo. She has already been approached by tech company Furious Minds with offers to help her develop and distribute the app.
