Add More Health Tracking Features
There are a lot of third-party apps that integrate nicely with Apple Health. However, there are some that seem unnecessary and would be far more useful as features integrated into the health app itself. Apple added hand washing as a trackable data point when using an Apple Watch. It would also be nice to see them add options for logging water, food items, toothbrushing, and medications.
While there are apps that offer these, and some can be done using Shortcuts, having this as an aspect of the app would be far more useful. Especially medication tracking. Since Health information can be shared with medical professionals, it would be useful for known medications to be tracked. They could even add the ability to refill medications with Siri or straight from the Health app.
