Is there an app to help me stay fit? If yes, can you mention it?

There are lots of fitness apps around that can make you stay fit if and only you follow the instruction with a great deal of discipline, determination and dedication. however, I must say, just as the internet is accessible to anyone with a computer knowledge, so  can the information of it or any app be misleading. The best thing would be to dedicate a part of ur daily life towards fitness. could be walking, jogging or even investing in a gym membership and a personal trainer to be with you through your fitness journey. you might say gym and personal trainers are expensive, but that could be the greatest investment you'll ever make regarding your health. could save you lot more in finances and resources at the long run. after all. an healthy lifestyle boost self confidence, Health and promote long healthy life..

I hope this gives you a bit of answer..
