I have heard about one fitness app from friend which is providing many features. It is having calorie meter about almost all kind of food even for local food of my country. Not only calorie it can also tells about other feature of food like how much fat it contains and how much protein and other important thing it have. It can also track the daily food we are having and how much we need to cut out for losing weight. It is also having trainer option where trainer can guide us through video chatting. But we need to pay for it. But it should be reasonable charge. So what do you think? I haven't tried anything like this, but can it replace the actual gym and save money like that way?
