The editable fields
From the Profile tab you can edit, each in its own quick sheet:
- Name — tap the Name row in the Profile group.
- Units — metric or imperial, applied everywhere instantly.
- Energy unit — kcal or kJ.
- Height — entered in whichever unit system you use.
Units, energy unit and height live under Profile → App preferences → Measurements and units. The Email row in the Profile group shows your email; tap it to copy.
Changed elsewhere, on purpose
Two numbers people look for here live in Body Metrics instead, because they're measurements, not settings: your current weight comes from weigh-ins, and your body-fat percentage from body measurements. Log the new value there and everything that depends on it updates.
What stays fixed
A few setup answers currently have no editor: birth date, sex, daily activity level, exercise frequency, and cardio experience. They feed the baseline formulas — the initial expenditure seed and your automatic water target — and creating or editing a program doesn't re-ask them.
The honest reassurance: their influence fades by design. Your expenditure is measured from your real data rather than recomputed from those answers, so a stale activity level from months ago isn't steering your targets — your logging is. If a setup answer was genuinely wrong and it bothers you, support can help.
