Domino's Pizza

Cost: Free

For fast-food pizza lovers, the Domino's Pizza ( DPZ) app is the quickest way yet to order the company's pizza for delivery.

After entering your delivery information into the app, you can browse Domino's complete menu of pizzas, pastas, sandwiches, etc. Once you select a pizza, you choose from a pre-made pie (Pacific Veggie or Philly Cheese Steak), or design your own. You pick your size and crust style, then customize the pie with cheese, sauce, meats and veggies.

You can also specify what to put on each half -- say, mushrooms on the right, sausage on the left.

The best part of the app: a pizza tracker that lets you follow your pie from the oven to your doorstep.

From the time we ordered our pizza via the app, it took around 30 minutes for it to reach TheStreet's office.
