What's the best iOS app for tracking outdoor runs with GPS and sharing progress?

Map My Run GPS Running Tracker is designed specifically for runners who want comprehensive tracking of their outdoor activities. The app uses GPS technology to map running routes with precise distance and elevation data, while also recording pace, calories burned, and duration. For users looking to share their progress, the app includes social features that allow connecting with friends, posting workouts, and participating in challenges. Reviews indicate the interface remains straightforward even after years of use, with many users reporting it helps maintain exercise consistency. However, some users have experienced persistent issues with the friend-adding functionality, where sent invitations fail to register properly. The app syncs with various health platforms and wearables, making it practical for those already invested in fitness ecosystems. Audio feedback during runs provides real-time updates without needing to check the screen, which is particularly useful for maintaining pace during longer distances. While the free version covers most essential features, certain advanced analytics require a subscription.
