JoinTheChallenge helps you live a healthier lifestyle and invites you to try our app, with your first 30 days FREE! We made the easiest app for tracking your food, water, exercise, steps, and weight, while giving you the feedback you need. Our advanced traffic-light food rating system gives you immediate feedback on your food choices, and even lets you see entire restaurant menus (largest health rated menu database with over 66% of U.S. restaurants), with every item rated, when you are eating out.


“The smartphone app, incorporating the [traffic-light] system, has the potential to improve nutrition; reduce the risk of developing diabetes, hypertension, heart disease, and stroke; and improve public health.” – A study of JoinTheChallenge’s system published in the Journal of Diabetes Science and Technology

- Green Rated Foods: the most healthful and nutritious foods with the lowest calories, calories from fat, total fat, saturated fat, cholesterol, sodium, and carbohydrates.
- Yellow Rated Foods: medium healthful and nutritious foods with 35% more calories than Green rated foods.
- Red Rated Foods: the least healthful and nutritious foods with 60% more calories than Green rated foods.

- Water Tracker: Use our water counter to track how much water you’ve been drinking and reach your goal of 8 cups (64 ounces) of water per day.

Great way to stay on track

This app makes it easy to track daily intake and makes eating out easy. Easy to use and quick entry. Water tracker is great too!

Old and limited

Restaurants for my "location " we're out of date or closed, food menu had 3-7 item. The items I would never even eat. Ratings for common sense items. Very disappointed will be deleting right after I submit this.

Amazing concept!

Living in a city like NY and trying to lose weight is a huge struggle. Always on the go and this app helps keep me in check and make the right choices while still living my life.
