Of all the Health app features introduced in iOS 16, the new Medications feature may be the most practical. According to the CDC, 48.6 percent of Americans take at least one prescription medication a day. Unfortunately, an NIH study found that 30 to 50 percent of patients don’t adhere to long-term medications — in other words, they don’t keep to their medication schedules. This is a problem that costs the healthcare system hundreds of millions of dollars per year. In iOS 16, however, you can log and schedule which medications you take and set up reminders on your iPhone or Apple Watch. You can also share your medication list with loved ones or healthcare providers.
