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

<!-- Nav order: Home, Products, About on page A; About, Home, Products on page B -->

Why it matters

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

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.

<!-- Same nav component, same link order, on every page -->

Repeated navigation must appear in the same relative order across every page it's used on.

Outcome

On a pharmacy app's prescription-refill form, this barrier is gone for people who navigate by memory and routine — they no longer have to work around this.

Who is affected

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