Apple Health. I find it incredibly useful for several things as I have a Watch that is passively tracking vitals and activity at all times, but the medication logging and reminders is particularly useful.

To play devils advocate, is it possible these permissions are just placeholders until the app is actually released?

People asked Apple for this, and when they obliged, it sold so terribly that retailers literally could not give them away. Unfortunately, it seems those who actually want smaller phones are a vocal minority
