For example, if you use the phone's camera to pan around your surroundings, the application will tag businesses in your area and give you the option to learn more about them.
If you take a picture of a book, the app will generate links to compare prices and preview the text.
Have you ever wanted to control the music on your computer from across the room? If so, check out Gmote.
The relatively new app turns your Android-powered cell phone into a remote control so that you can run movies and music from a distance.
Not only does it let you select play, pause and rewind and adjust the volume, it also lets you choose what to play.
For the Droid user looking to stay fit and get some fresh air, Cardio Trainer is as essential as running shoes. The free app records your outdoor workouts, including running, walking, skiing, horseback riding, kayaking and skating. It uses a built-in pedometer and GPS technology.
It can also keep track of indoor activities on a treadmill, stationary bike, ski machine or track. Cardio Trainer automatically pauses and resumes as you stop and start moving.
Want to run four miles, burn 400 calories, or race against your record time? Cardio Trainer will help you do all three.
(Note: you must pay a one-time $2.99 fee for Weight Loss Trainer and Race Against Yourself after free trials for those services expire.)
Do you get embarrassed when your phone's ringer goes off during class or while you're in a meeting?
Meet Locale. The award-winning application lets you assign specific phone settings to different situations.
If you don't want your phone to ring while you're at work, you can manually enter your office's address, or use a touchscreen map, to set up a no-ring zone around your workplace.
The app even allows you to set it so that calls from family members and other VIPs come through no matter where you are.
You can also use the application to provide location-based reminders, such as charging your phone when you walk through your front door.
It might take some time to configure the settings to your liking, but once it's done you won't have to think about it again.
Finding restaurants, bars and coffee shops is a cinch with the free Yelp app.
Yelp figures out your location using the Droid's built in GPS, then tailors recommendations based on what you're searching for, whether you have in mind a particular eatery or just a type of cuisine.
It also has categories to help you fine drug stores, banks, gas stations, and even sales and special offers from businesses listed on Yelp.
