6 Apps That Will Make You Skinny!

1. Nike Training Club Free: 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.
2. Zombies, Run! $7.99: This brilliant app submerges you in a highly interactive audio adventure. Co-created by award-winning novelist Naomi Alderman, the guttural breaths and rattling groans of the walking dead get closer, surrounding you on every side -- all you can do is run!
3. Fooducate Free: 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.
4. RunKeeper Free: 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.
5. The Snack App Free: 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.
6. Gorilla Workout, $1.99: Gorilla Workout has more than 40 routines that are targeted at specific muscle groups, including your abs, arms, or legs. With a mix of cardio and strength training, the app will help you shed excess fat where you need to most and build muscle elsewhere in a short amount of time.
