Aplifit tracks two essential types of data: Heart Rate and Watts Data. Heart Rate Data: Aplifit monitors your heart rate during workouts, allowing you to gauge your exercise intensity and cardiovascular performance. This data is crucial for optimizing your training routines and ensuring you're in the right heart rate zone for your fitness goals. Watts Data: In addition to heart rate, Aplifit tracks watts data. Watts provide valuable information, especially during activities like cycling. It helps you understand your power output and efficiency during your workouts, making it easier to set and achieve performance goals. By collecting both heart rate and watts data, Aplifit offers a holistic view of your fitness metrics, empowering you to make informed decisions and progress towards your fitness objectives.
