Outdoor Run++ is a convenient and user-friendly iPhone app that allows you to track your outdoor workouts using your phone's GPS. Whether you're walking, running, biking, or even driving, this app provides you with accurate data on distance, time, speed, pace, and calories burned.

One of the standout features of Outdoor Run++ is its ability to display distance, pace, and speed measurements in both miles and kilometers. With a simple swipe on the distance label, you can easily switch between the two units, even in the middle of a workout.

Another useful feature is the app's mapping capability. Outdoor Run++ saves a map of your workout path and displays mile or kilometer markers along the route. You can also mark specific locations on your path, allowing you to track the distance and time it took you to reach each mark.

For those who engage in multi-section workouts, Outdoor Run++ has you covered. The app offers a "Start", "Pause", and "Resume" sequence to track your multi-section workouts. In the workout summary, you can view each section of your workout under "Workout Splits".

If you grant access to Outdoor Run++ to read your health data from the Health app (HealthKit), the app can also provide calorie calculations based on your "Date of Birth", "Sex", "Weight", and "Height" information. However, if you choose not to grant access, the app's functionality remains intact, except for calorie calculations.

Please note that continued use of GPS running in the background can significantly drain your battery life.

Overall, Outdoor Run++ is a reliable and versatile app for tracking your outdoor workouts. Its intuitive interface, mapping features, and multi-section tracking make it a valuable tool for fitness enthusiasts.
