Lark Chat (Free)
Looking for a less tedious way to track your daily diet? Instead of searching through a huge, confusing database, just speak into your wrist and Lark will log your meals and sleep patterns for you. And don't worry about keeping track of all your fitness data—exercise is automatically tracked by your Apple Watch's built-in motion sensors. The app uses artificial intelligence to create your own personal health coach, so you can get feedback tailored specifically to you and your habits 24/7.
