This holiday season was one of the busiest for Apple's App Store. Millions of people activated their Android and Apple devices for Christmas, and their first stop was the App store for both systems. On Christmas Day alone 242 million apps were downloaded according to market research firm Flurry.

If you were one of the lucky ones who received a new iPhone for Christmas, then you might be wondering what apps you need for your new phone. Or you might be looking for apps to help you stick with your New Year's resolutions. Here are the top five apps you should have on your iPhone.

Lose It

Any iPhone user who's looking to lose weight this year should have the app Lose It! in his or her iPhone. This free app will let you track your food intake and tell you what foods affect your daily caloric limit most. The app also informs you about exercises that will reduce those calories and give you recipes for healthy foods. The app is even a great motivator, because it encourages activity by giving badges for healthy activities and eating. Lose It! allows lazy users to share their progress through their social network to let friends goad them to make their daily limit. Lose It! is a great app to lose those love handles and lead a healthier lifestyle.

Flipboard

The new iPhone version of the popular iPad app has been so in-demand that it reportedly crashed the company's servers as 1 million users downloaded Flipboard in its first week. Flipboard is a digital magazine that is personalized to your own interests. The app creates a stylized magazine from content gathered from your social networks like Facebook or Twitter. The app fills out the magazine-like view with content tailored to your reading history. It's one of the best content viewing and sharing apps for the iOS.

Mint

If you're looking for an app that will help you stick to your budget this year, you don't need to look further than Mint. The app lets you add your personal information, including bank accounts and credit cards, to let you track your spending. Mint also creates a budget based on that information and even reminds you about bills to pay. It's a safe and easy way to keep track of your finances.

Evernote

If you're a forgetful person, you need to have Evernote in your iPhone. The app will let you create notes of things you need to do and stores important files for safekeeping. You can create text, audio and photo notes and sync them to other devices. You can even mark notes as "favorites" for easier access.

Lookout Mobile Security

Apple may not suffer from the same amount of malware that Android systems deal with, but it doesn't mean that you should completely forget about mobile security. Lookout Mobile Security, the security software that's been protecting Android and Blackberry users for some time, released a version for iOS in October of 2011. The iOS version lets you find your lost iPhone, back up your contacts, and manage your settings to avoid your phone from connecting to unsecured Wi-Fi networks. Lookout for iPhone also warns if the device is jailbroken or if it doesn't have the latest operating system updates installed.
