Google Fit

The Google Fit app works with the system developed by Google in association with the World Health Organization (WHO). The system was declared as the most common and useful method to record and analyze human physical activity. The service doesn't need to be launched. You just install the application, create a profile, and then Google Fit works. The app can identify steps, running, and cycling. It also counts the distance in steps, the number of calories burned, and gives recommendations depending on your results. Thanks to the application, you will always be informed of how many miles you have passed, ran, or traveled.

According to the developers, there are two simple fitness indicators you have to analyze: minutes of activity and cardio training points. To stay fit and healthy, you have to move. For any movement, the user receives additional minutes of activity that motivate him to slightly change the mood of the day and make it healthier. For example, you can go up the stairs and not use the elevator, or go for a walk with friends instead of a meeting in a cafe.

The Google Fit app was designed by Google for Android devices.

MyFitnessPal

MyFitnessPal is one of the most popular calorie counters among Android and iOS users. In addition to its main purpose, the application also has another one. MyFitnessPal works as a social network where users can share experiences with those who have the same diet, lead a sporty lifestyle, and strive to achieve a perfect body shape. To start using the digital food diary, you must go through the registration procedure. It is not difficult to do this, because the service will ask you to enter the mail address and confirm it using the sent link. There is also a second way: you can log in via Facebook.

Entering both data and goal setting are the two most important parameters in MyFitnessPal nutrition log. Based on this information, the system generates tips, advice, and reporting. The service fixes the date of parameters entered and puts the indicators in graphs. They can be found in the Reports tab. Update your own parameters, for example, once a week, and with the help of charts, you can analyze your progress.

Your goals are set on a separate relevant page. Set how much you want to weigh and how many times you want to train. When you set the desired total weight, the system makes recommendations regarding the minimum or maximum calories consumed per day.

MyFitnessPal is available for both Android and iOS users.

321FIT

Last but not least. 321FIT looks like a simple music player, but instead of music, it plays exercises. The principle works this way: you choose and create music presets, and the app suggests a training program based on the music style. For example, if you created a heavy metal playlist, the app will suggest a hard gym training to gain some muscles.

321Fit works with Apple and Android devices.
