Marathumb is a free iPhone app developed by Wolverine World Wide Inc. It falls under the category of Lifestyle, specifically Health & Fitness. The app aims to challenge users to move their feet more than they scroll through their social media feed.

Upon downloading the app, Marathumb will monitor your step count and encourage you to beat the average national scrolling distance. By doing so, you can earn Saucony rewards. The challenge lasts for 6 weeks, starting on Monday, January 22.

The app allows you to check your stats, monitor your activity, and receive Marathumb Motivation to keep you motivated throughout the challenge. You can also share your progress with your friends, making it a fun and engaging experience.

Don't miss out on the opportunity to give your thumb a break and focus on moving your feet. Join the Marathumb Challenge by downloading the app today!
