How would you like to make a little bit of money from your smartphone -- emphasis on the "little"?

EasyShift is a free app for the iPhone, iPod touch, and iPad that lets you essentially be an on-demand secret shopper. You're assigned 'shifts' by product manufacturers who want people on the ground to go into stores and confirm that their merchandise is being displayed properly.

The pay rate for a shift is between $3 and $8 and the money is remitted to you via PayPal. Now, you won't get rich from this -- think of it like micropay for microwork -- but who couldn't use $3 toward a meal on the value menu at your favorite fast food restaurant?!

Meanwhile, if you're in the Android world like me, there's a competitor to Siri called Skyvi that I've found very impressive. Just like Siri, you simply ask the Skyvi app any question -- for example, where's the nearest burger place? -- and it replies to you with amazing accuracy. Skyvi is free for a limited time at the Google Play store.
