I'm a sucker for deals. I singlehandedly discovered this drugstore eye cream that works just like La Mer; I'm the queen of designer finds at thrift stores; and I'm all over Groupon like smoked gouda cheese on a whole wheat cracker.

And my latest dollar stretcher? These 7 fitness apps.

These 7 apps have the latest in GPS, motion sensor, and bar scanning technology to give you the tools you need to get in the best shape of your life -- without draining your wallet. See them now.

NIKE TRAINING CLUB, FREE

Sure, Adriana Lima and Rihanna have amazing bodies. They also have amazing personal trainers. And now we can, too. Thanks to Nike Training Club, you can get exclusive workouts from celebrities like Lea Michele, athletes like Shawn Johnson, and even from Rihanna's personal trainer, Ary Nunez. With access to 85 custom-built workouts, these drills build on the fundamentals of strength, cardio, interval, and core training to help you tone your body like an A-lister. With the audio instructor and video demonstrations available at all hours of the day, it's like having a personal trainer at your beck and call.

FOODUCATE, FREE
When it comes to losing weight and being healthy, it's not only about decreasing the quantity of food you eat, but increasing the quality of your foods, says Zoe Diana Draelos, MD, PA, board-certified dermatologist in High Point, N.C. While it's easy to figure out what's healthy in the vegetable aisle (uh, everything!), when it comes to packaged foods, things get a bit dicey. We're smart enough not to believe all "healthy" and "low calorie" claims on packages, but who has time to stand in the canned foods aisle for 20 minutes trying to make sense of the nutrition labels? Enter Fooducate. Simply scan the product's barcode with your phone, and you'll instantly know the healthfulness of the food with Fooducate's letter grade.

RUNKEEPER, FREE
Do you decide that you're going to run, yes run, a full three miles -- but end up walking the whole way? That's when a personal trainer yelling at you through a megaphone would come in handy. But if you don't have the funds for a human trainer, why not opt for a digital one? RunKeeper uses the GPS technology in your iPhone to track your fitness activity, giving you comparable results to those expensive GPS watches. The app tracks how far you went, how long it took you, your pace, and how many calories you burned. You can even enter your target pace, and the app will coach you (through your headphones) on whether you're ahead or behind. Genius.

THE SNACK APP, FREE
After carefully counting all your meal points and conforming to the gym rat lifestyle, you may have moments when you just need a freaking sugar fix. Instead of running to Mrs. Field's or Krispy Kreme (and binging on a dozen in the shameful darkness of your car), click open the Snack App. With hundreds of snack options, you can satiate your craving responsibly by choosing a 50-, 100-, or 200-calorie snack in the category of your choosing: salty, sweet, cheesy, or even sinful. Each snack suggestion comes with a nutritional breakdown so that you're aware of how much you're consuming even in your moment of weakness. And the app will also show you exercise options to burn off those calories if you're feeling post-binge guilt.

LOSE IT!, FREE
You know that sage advice about keeping a food journal? And how you never follow it? Logging in your food and exercise regimen is now made easy thanks to this handy dandy app. Aptly named "Lose It!," more than 85 percent of the app's users report that they've lost weight. With this app, you can find foods that you buy at your local grocery store or order at a restaurant and log it into your "journal." It tallies up your calories for you, while keeping track of your nutrient intake, including your protein, fat, and carbs consumption. You can also plug in your exercise routine, and the app will automatically deduct the calories from your overall daily caloric count.

POINTS CALCULATOR PLUS, $1.99
Jennifer Hudson swears by Weight Watchers; you and half your office attend the WW meetings together. But any WW convert knows that the program doesn't work if you don't accurately keep track of your points. Introducing the new Points Calculator Plus. This app tallies up your food points for you -- no need to carry around a bulky calculator and deal with the slight embarrassment of whipping it out in a posh restaurant. What's more, you won't ever have to question the point value of your meals. You can quickly search the food item in question with the app's database, which will spit out the point value immediately. Counting made easy.

SLEEP CYCLE ALARM CLOCK, $0.99
Did you know that your body burns calories while you sleep? For example, a 120-pound person burns about 408 calories with eight hours of shut-eye, which has to be the easiest and most relaxing way to lose weight in our book. That is, until the alarm clock goes off smack in the middle of your "cruising on a yacht with George Clooney" dream. Then you're just tired and cranky. We feel the most tired when we get woken up during a REM cycle, which is when our brain is in its deepest sleep. By using the accelerometer in your iPhone to monitor your body's movement, this app will wake you up at the most optimal time to give you the most rest (and burn the most calories). Now, you can finish your George Clooney dream in peace.
