This is a website and it is also available as an app on iOS and Android. MyFitnessPal helps track your workout progress by calculating your calorie intake and managing your diet plan. Therefore, for those of you who are on a very strict regimen, it is great because you can input your entire daily intake. All you have to do is click at the diary and you can input all of your meals as well as exercises for the day and your water intake. The best thing about this is that it has such a large library of different types of foods. Say that you order a dinner plate at a popular chain and most likely MyFitnessPal already has all the nutritional content of that meal. So all you need to do is to look it up and add it. It calculates the nutritional content of fruits, vegetables, grains and all sorts of things. That’s what I really like about this app. If you have a heart rate monitor recording the heart rate statistics of your daily activities, then you can input that data into MyFitnessPal app. The app will adjust for how many calories you need to consume in order to meet your fitness goals. This is an awesome app for those of you who are on your weight loss journey or if you are an athlete and want to make sure that you are making progress or whether you are a bodybuilder and want to track your macros. If you are someone trying to gain weight, you can definitely use this app as well. The only downside of this app is if you get too caught up in every little number. You need not get stuck up on the numbers and you do not have to meet every single criteria.
