Every year you make them, and every year you break them.
Will power can be hard to come by, but applications that help you lose weight, get fit, quit smoking and accomplish countless other goals are just a click away.
Here are 10 apps that might help you stay on track.
It's among the most often repeated – and most often abandoned – resolutions.
But losing weight can be made a little easier with a free iPhone app from the developers at FitNow, Inc.
Let's say you want to lose 20 pounds in time for a summer vacation, the app will calculate the daily calorie allowance that will get you there.
The app also includes a comprehensive database with the caloric values for thousands of food items, including meals on fast food restaurant menus. Once you've set your weight loss goals, you enter your daily food intake and exercise to make sure you're not exceeding your daily limit.
So you can't afford a personal trainer? For $1.99, you can get one that fits in your pocket.
One of the most popular applications in the App Store, iFitness will suggest illustrated workout routines to keep you in shape.
Flabby arms? Touch "arms" on the menu and find the best exercises. Worried about your abs? The program will suggest a routine.
It will also keep you honest. You can keep a log of what you've done, get an idea of your progress and even generate graphs of your results to keep you motivated.
Nagging friends can't get you to do it, but maybe an iPhone app will.
My Quitline is a free application that links users to a the National Cancer Institute's quitline where you can speak to a live coach. The app also includes a live text feature to get advice on quiting.
Launched in April, it was developed by The George Washington University's School of Public Health and Health Services (SPHHS) and the National Tobacco Cessation Collaborative (NTCC), with support from the National Cancer Institute (NCI).
If you're a results-driven person, check out Quitter. The free application tracks how long you've been smoke free and calculates the amount of money you've saved as a result. Just type in the cost of a pack, the number you smoked each and the day you went cold turkey.
Especially after a season of spending, who doesn't want to save?
If this is your resolution of choice, take a look at Mint.
The free iPhone application helps users track and manage spending. It shows you how much you spend, how much you make and doesn't even require you to key in transactions. It automatically syncs with your bank account and alerts you when you're low on cash or credit or when it spots unusual activity.
If you've resolved to get more sleep in 2010, check out Pzizz. The oddly-named application is on the pricey side -- $9.99 – but it's among the top-rated Medical applications in the App store in several countries.
The company behind it (Pzizz Technology Limited) says it cures insomnia by playing unique soundtracks each time the app is used. Users can also set the amount of time they want the relaxing music to play.
If you want to get organized but don't know where to start, download Personal Assistant.
The application comes in free and paid ($6.99) versions and turns your phone into a one-stop shop for all of your online accounts. Credit cards, bank accounts, cell phone minutes, frequent flier miles, Netflix queues and more can be monitored from the one account.
Though the free version is comprehensive, the paid version gives you extra security, real-time flight information and an ad-free experience.
Shopping responsibly always sounds like a great thing to do – until you get to the store. But the Good Guide iPhone app simplifies the process considerably. The free application provides ratings for health, the environment and social responsibility for more than 65,000 products. All you have to do is use the iPhone's camera to scan the products' barcodes, and information about ingredients, company controversies and more will display on the phone's screen.
When it comes to beating stress, it sometimes seems like the more you try, the harder it is.
But a new application from the Mayo Clinic will give you a clinically-validated approach to improving focus and relaxation.
For $4.99, Mayo Clinic Meditation provides a short training video on meditation concepts and then leads you through 5 or 15 minute meditation programs.
Using musical chords and soothing images, the application helps users slow breathing and reduce stress. It also offers tips for staying focused and calm that can be shared with family and friends.
Make 2010 the year you get out of the house to lend a hand.
With Catalista, a free iPhone app launched in September, you'll be able to find opportunities to volunteer with local nonprofits around the country. The application lets you search by areas of interest, location and available time and lets you track hours volunteered.
It includes more than 250,000 opportunities and gives users the option to request opportunities if there aren't any listed in their area.
Finally, if your goal for 2010 is to stretch your mind, the App store has plenty of options for you.
If it's your vocabulary you want to improve, check out Word of the Day (All-in-One). For $0.99, it aggregates words of the day from many popular online sites, from Merriam-Webster to the Urban Dictionary to even the National Scrabble Association.
Or if your interests are more general, the App store includes free apps from the Louvre Museum, NASA and Technology, Entertainment and Design (TED) conferences.
