RunFit is a lifestyle app designed for iPhone users, developed by Mathieu Savaria. It focuses on tracking and displaying your weekly running and walking progress on your Apple Watch faces. The app offers a simple native design, supports various complications, automatic data refresh, and more.

With RunFit, you can easily monitor three key weekly metrics: distance covered, running time, and quality time. By resetting the data every week, users can start fresh and track their training progress effectively.

The app also allows users to compare their current week's training with their past history, indicating progress with up or down arrows. RunFit ensures privacy by saving weekly data securely on iCloud and supports various workout apps that integrate with the Health app, ensuring compatibility and convenience for users.
