Activity Guide
Activity Guide shows how active you've been during the day. It also tells you how much you need to do to reach the global recommendations for physical activity. With practical guidance like 'walk for 50 minutes or jog for 20 minutes' you can choose how to reach your daily activity goal. Meet your goal faster with more intense activities or stay active at a slightly more moderate pace throughout the day.
Activity Benefit
Activity Benefit tracks all your active choices during the day and shows how they help you stay healthy. It'll reward you when you've done enough and make you move if there's still a bit missing from your daily activity goal. Activity Benefit gives you daily, weekly and monthly feedback, because the more you move, the greater the health benefits. You can check Upon how you're doing either from your mobile or from the web.
Smart Calories
OwnCal is the most accurate calorie counter on the market. It calculates the number of calories expended during a training session based on your weight, height, age, gender, your individual maximum heart rate (HRmax) and how hard you're training.
Heart Rate Zones
Select and monitor the intensity of your training easily with heart rate zones and follow heart rate based training programs. The default heart rate zones are based on your maximum heart rate: very light (50-60% HRmax), light (60-70% HRmax), moderate (70-80% HRmax), hard (80-90% HRmax) and maximum (90-100% HRmax).
EnergyPointer
If you want to improve your fitness or burn fat, EnergyPointer is an easy-to-use feature that visually shows you what the main effect of your training is so that you can focus on what you want to achieve.
Training Benefit
