1. Time Period — not sure what this refers to. Why is the maximum only 30 days or one month? I think some text to explain that screen would help.
2. Resting Heart Rate — I don’t know what to choose and there is no information or link to sources that could help decide.
3. Metrics and Goals — what time period are those goals over? Is that related to the Time Period setting? Or is it weekly? Why are there goals and toggles for “Vigorous Exercise” and “Moderate Exercise” in addition to the zone wise toggles? How do these overlap with the zones? Again, reducing the goals and toggles and/or adding text and/or reorganizing this may help (for example, “Vigorous Exercise” could just be a heading for zone 5 and zone 4, “Moderate Exercise” could just be a heading for zone 3 and zone 2 — I don’t know if this even makes sense).
As someone else said, an onboarding flow with explanations and choices for settings could really help (and the user could be instructed that if needed, they can change these in settings later).
Looking at my “Vigorous Exercise” number on the main screen, I don’t know if I should aim to increase it or not. Some guidance on what goals to aim for, with the caveat that the user should consult a medical professional to decide on exercises appropriate for them, would also be useful.
Edit: I see that there’s some information in the Help & FAQ and About pages linked from the i (information) button, but it doesn’t cover everything from my feedback above. I still think these should be in the onboarding flow and easily accessible again within the app (without opening a web page).
