Many health apps also provide personalized recommendations and reminders to encourage users to maintain healthy habits. These apps often include features like step counters, calorie trackers, and guided workouts. Some may even connect with wearable devices, such as fitness trackers or smartwatches, to provide real-time data. Popular examples of health apps include MyFitnessPal, Fitbit, and Headspace, each catering to different health-related needs.
