Mobile Navigation Order That’s Inconsistent With Itself

3.2.3 — Consistent Navigation

Scenario

Setting

A pharmacy app's prescription-refill form

What’s wrong

Mobile nav ordering diverging from itself across pages (not vs — desktop — across pages in the same presentation).

Example

A tester reviewing a pharmacy app's prescription-refill form finds this: mobile nav ordering diverging from itself across pages (not vs — desktop — across pages in the same presentation).

Why it matters

People who navigate by memory and routine, including many with cognitive or low-vision needs. The practical effect on a pharmacy app's prescription-refill form: they lose confidence they're in the right place.

How to test

Compare mobile navigation order to itself across different pages (not vs — desktop): inconsistency across pages in the same presentation fails.

How to fix

Repeated navigation must appear in the same relative order on every page in the set.

Outcome

That one change on a pharmacy app's prescription-refill form means they move confidently between pages.

Who is affected

People who navigate by memory and routine, including many with cognitive or low-vision needs.
