In our modern lives, mental and physical health is an increasing concern. Using apps and sensors on our iPhone and in accessories we can connect it to, there are many ways in which your iPhone can assist you. iPhones can count the steps we take as we carry them with us. Workout apps can offer training and encouragement to keep ourselves fit. They can give us an outlet to journal our thoughts. Recent additions include mood tracking and mental health assessment questionnaires which assess our danger of anxiety or depression. Meditation apps like headspace can provide numerous mindfulness tools. There are also books and podcasts which our iPhones can help us find and access. We’ll take a whirlwind tour of all of these and hopefully provide enough information to get people started.
