Looking for a good calorie counter for your Windows Phone? One that will sync with an online service? Have we gotta deal for you.

For a limited time only (until the end of August 2011), the Windows Phone app Calorie Tracker-LiveStrong will be free. As the title implies, Calorie Tracker is part of the Lance Armstrong foundation and normally runs $2.99 over at the Marketplace.

LiveStrong has a searchable database of over 625,00 foods and will display the nutritional information (calories, protien, fat, sugars, carbs, etc.) for each. If you need to find and track the calories you burn during workouts, Calorie Tracker will do that too. Everything can be tracked on your phone and synced with free online service at Livestrong.com, The Daily Plate.

So if you're dieting, need to keep track of what you eat or track your workouts Calorie Tracker is worth checking out. Especially during this freebie offer. You can find Calorie Tracker here (opens Zune) at the Marketplace.
