DULUTH-Need a last minute Father's Day gift idea? Why not go digital? Workers at Duluth's Verizon Wireless store saying some nice app ideas might be "Grill guide" (a huge library of how to cook over the coals) or even "The Carpenter App" (putting different tools on your cell phone).There’s also “Golf GPS Tracker” that lets app users estimate distance on the links. "There's a free app and a paid version,” Ryan Aho with Verizon Wireless said. “The paid app has more courses but it does have like five of the local courses in the free version." There’s even a twist on a classic gift with “The Pocket Watch” app.
