A fitness app is like a special helper that goes on your phone or tablet to help you get healthier and stronger. It's like a coach that helps you do exercises, eat better, and track your progress.
When you open the app, you can usually choose from different types of workouts like running, yoga, or weight lifting. Then, the app will give you instructions on how to do the exercises correctly and safely. It might also give you tips on how to make the exercises harder or easier, depending on your level of fitness.
Sometimes the app can also help you set goals, like running a certain distance or doing a certain number of push-ups. It might remind you when it's time to exercise or eat a healthy snack.
There are also usually tools in the app that help you keep track of your progress. You can record how long you exercised, how far you ran, or how many calories you burned. You can also record what you ate and how many glasses of water you drank.
Overall, a fitness app is like a little buddy that helps you take care of your body and reach your health goals!
