JUSTMOVE is a free lifestyle app developed by RaceRunner Inc. for iPhone users. The app allows runners to compete against others around the world, making their daily runs more exciting.

The app offers two types of races - real-time and flextime, where runners can compete against others on their everyday running routes. Runners can also create their own races and invite their friends or running partners from anywhere in the world to compete.

JUSTMOVE also lets you track your activity through your profile, providing in-depth analysis and statistics about your performance in each race. You can track your overall pace and all-time distance to see your improvement. The app also allows you to show off the medals you earn by placing in the top three in global races.

With the free run feature, you can track your marathon training, whether it be walking, jogging, or running, and keep track of your distance, pace, and calorie burn to see how you will stack up during your next race. The app is integrated with Apple Health, syncing all your walking or running done with Apple Watch, and can also sync with Garmin, Suunto, and Polar devices. You can even add them to virtual races.

Overall, JUSTMOVE is a great app for runners of all levels who want to add a bit of competition to their daily runs and track their progress.
